Randall converted an Arduino into AVR chip programming hardware for use with AVRDude. The project programs AVR tiny13 and other tiny AVR chips using an Arduino.
He provides code and instructions to implement the Atmel AVR910 In System Programming protocol. I ported the Atmel AVR910 In System Programmer protocol to the Arduino. Now I can write programs to my ATtiny2313 and tiny13 chips. The Arduino sketch is available for download here. It works with the AVRDude programming software. This article will show how to use the Arduino to upload a program to the tiny13. The first step is to download the zip, extract the.pde file, then load it into the Arduino IDE, and write it to the Arduino.
Next we can hook up the tiny13 chip. This example shows how to make use of the Watchdog and Sleep functions provided by the ATMEGA168 chip (decimila). These functions are useful if you want to build low power consuming devices operated by battery or solar power.The reduced power consumption is achieved by through a intermittent operation of the system.In case of Arduino your main loop will be executed once before the system is put into the sleep mode. After a few seconds t the watchdog wakes the system up and the main loop is executed again. The ratio between main loop execution time and watchdog time determines the amount of power that will be saved.When we assume that the time to measure a sensor and making some decisions will take 10 millisecond and the watchdog is set to 8 seconds the on/off ratio is 800 which extends the battery live time by this factor. If you are looking into wireless communication between two Arduino modules, this project might be helpful. It uses low costs RF transmitter and receiver from Electronics-DIY.com to establish radio link between two Arduino boards up to 500 ft.
While question-and-answer exchanges make up the bulk of the items featured here, also included are journalistic profiles of the director at work and essays Frankenheimer himself wrote for magazine audiences.
Data can be transferred serially at the maximum rate of 2400 bps. The schematic shows how receiver and transmitter is hooked up to two different Arduino boards. When wiring the receiver / transmitter you only need to give them power / ground and then a pin for the TX (serial transmit) or RX (serial receive) pin.
I also wired a button to the Arduino doing the transmitting, and used the LED on pin 13 that is built into my Arduino boards on the receiver so I could test this setup. The test app just flashes LED on the receiving board when a button is pressed on the transmitting board. Arduino Sine wave Generator using the direct digital synthesis Method.Here we describe how to generate sine waves with an Arduino board in a very accurate way. Almost no additional hardware is required. The frequency range reaches form zero to 16 KHz with a resolution of a millionth part of one Hertz! Distortions can be kept less than one percent on frequencies up to 3 KHz. This technique is not only useful for music and sound generation another range of application is test equipment or measurement instrumentation.
Also in telecommunication the DDS Method is useful for instance in frequency of phase modulation (FSK PSK).The DDS Method (digital direct synthesis).To implement the DDS Method in software we need four components. An accumulator and a tuning word which are in our case just two long integer variables, a sinewave table as a list of numerical values of one sine period stored as constants, a digital analog converter which is provided by the PWM (analogWrite) unit, and a reference clock derived by a internal hardware timer in the atmega. To the accumulator, the tuning word is added, the most significant byte of the accu is taken as address of the sinetable where the value is fetched and outputted as analog value bye the PWM unit. The whole process is cycle timed by an interrupt process which acts as the reference clock. Further details of the DDS Method are described in web of course. This is versatile development board for AVR microcontrollers ATmega48/88/168.
It is good for testing and debugging embedded programs. It has many built-in peripheries connected to microcontroller so you can use them without soldering. ATmega microcontrollers are produced by ATMEL and they include a lot of features: I/O, Timers, PWM generators, ADC, RS232, TWI, SPI, Analog Comparator, Oscillator, EEPROM These microcontrollers are very versatile, easy to program and easy to use. This is the reason why I like these microcontrollers and why I decided to make development board for them. The LM35 of National Semiconductors that is used in this project is a precision centigrade temperature sensor, which has an analog output voltage.
It has a range of -55ºC to +150ºC and a accuracy of ±0.5ºC. The output voltage is 10mV/ºC. The output voltage is converted by the AD convertor of the AT Mega8. The temperature is displayed on an LCD module.
In this example the thermometer has a range of 0ºC to 40ºC and a resolution of 0.5ºC. If you want to have a readout in Fahrenheit you can use the LM34.
With this circuit you can control two unipolair stepper motors in full step mode via the RS232 serial port of your PC. A terminal program such as Hyperterminal can be used to control the stepper motors. The stepper motors can be driven one at a time.#Drives two unipolair stepper motors in full step mode#Accepts commands via the serial port of your PC.#Can be used with any OS that has a standard terminal program such as Hyperterminal.#Drives stepper motors up to 24V, 500mA#Power supply.12-24 VDC. The ATMEL AVR programmer works with the Windows program 'Ponyprog' which works under 95, 98, XP. And can be found at board the AVRs that can be programmed are those in the schematic.
Download Program At90s2313 With Arduino Lcd Tv
For other members of AVR family or the rest programmable ICs that Ponyprog can program, there is the J1 connector (CON10) which allows expanding the programmer's hardware. See Ponyprog's site for other's ICs Ponyprog circuits.
The JUMP1 jumper is there to connect the crystal's circuitry to the 8-pin AVRs or to disconnect it. Some AVRs have internal RC oscillator and an external XTAL is not allowed or needed.
Here's AVR programmer for programming AVR microcontrollers such as the AT90S1200 via the parallel port. AVR programmer is extremely simple. IC1 provides buffering for the signals that travel from the parallel port to the microcontroller and vice versa. This is essentially everything that can be said about the circuit. The two box headers (K2 and K3) have the ‘standard’ ISP (in system programming) pinout for the AVR controllers.
The manufacturer recommends these two pinouts in an attempt to create a kind of standard for the in-circuit programming of AVR microcontrollers. These connections can be found on many development boards for these controllers. The software of AVR programmer carries out the actual programming task. The AVR family of `micro-controllers' (uCs) have their own, non-volatile memory; your program and data are safe, even if all power is lost.
These chips also contain most of what is needed to program them. If you connect an AVR to the parallel port of a PC loaded with the right software - a `programmer' - then PC and uC will happily talk each other through the procedure. Uploading a program to the chip takes just a few seconds and very little hardware.
It can even be done while the uC is `in-circuit', sitting in the apparatus you want it to control. A program already in the chip can be erased by the same `programmer'; there is no need for ultra-violet light or a special power supply.
A bootloader enables download of hex-files directly into the flash-memory of a PIC or other microcontroller. The bootloader receives the user program via the PIC's UART and writes it directly to the program memory (self programming). This feature greatly speeds up the development process, because the chip remains in the target circuit and need not be moved between the target circuit and the programmer.When no bootloader is installed, all memory in the PIC can be utilized for user programs. That is 4 K for the 16F873 (0x000 to 0xFFF). Installing a bootloader means, that some part of the memory is occupied by the bootloader. The user can download his program into the remaining memory space. The bootloader in figure 1 occupy 256 words (0xF00 to 0xFFF), that is 6% of the memory in a 16F873.
The disadvantage of loosing 6% memory is little compared to the advantage of fast program download and more friendly development routines. Build a digital clock that turns AC load on/off through relay with preset time. The clock is based around 7-segment LED display with multiplex connection and AT89C2051 microcontroller. It is nice to be used as the display for clock controller. So I spent my weekend built the board. Below are the pictures for outlook and internal.
The board is quite small. The output has small relay for 0.5A AC load. The program clock.c was written in ‘C’ language and was complied by Micro-C Compiler from DunfiledDevelopment Systems. The memory model is TINY. The hex file of clock.c suitable for downloading by Easy-Downloaderis clock.hex.
CodeLock AVR electronic combination lock is realized with Atmel AVR microcontroller AT90S2313 or ATtiny2313. Program in hex code is 2 kB long. User code is consisted of 1 to 4 digits. If you buy the chip than user code is consisted of 1 to 8 digits. If the code is entered in the correct sequence, then after 1 second the relay and the electric striker (in the door) switch on for 1 second and then switch off again.
User code can be changed via 3x4 matrix keypad. Keypad for CodeLock can be bought at local electronic shop.Initial user code (1234) is set up with a jumper. The jumper must be inserted before the voltage (12V) connection. The jumper must be removed after 2 beeps (after 5 to 15 seconds).
Few years ago we control the lights in the garden with a automatic-timer-switch, very nice but when the evening gets longer or shorter we had to adapt the timer each week. In that time I came in contact with programming microprocessors so my first project was born. The first garden timer was a simple 1 output.
The timing was controlled by the PIC and every month I had to change the minutes. So back to the table and design the second garden timer able to control 3 relays - left, mid and right side of the garden. It provided also 4 modes: – always off – always on – from dusk to dawn – from dusk to timer and the timing was dedicated to a RTC DS1307. All remote controlled projects from this site can be controlled with remote controls which use the RC5 protocol, like the TV-remotes from Philips.When all buttons from such a remote are in use then you could make a remote control by yourself.Your own build remote control with only one button or maybe you want to build a remote with more then hundred buttons.It is possible, however, you need the PIC Basic compiler from Crownhill seeing that everyone has his own wishes and you have to fill in which button sends which RC5 code.
The JDM (or Ludipipo) seems to be among the most popular PIC programmers used - and rightly so: it is simple, cheap and easy to build, can be run with the free and excellent IC Prog software by Bonny Gijzen, and will program pretty much any PIC microcontroller on the market.However, an issue has arisen lately with some of the new PIC's, eg PIC12F675, 12F629, and some others with an internal oscillator.When these chips are programmed the first time, everything goes fine. However, if you later try to read or re-write to them, they read as blank and cannot be written to. The problem only occurs when the PIC has been programmed for INTOSC and MCLROFF, but even in this situation sometimes it will re-program OK - there seems to be some other dependence on the program which has been loaded as well.
This is a simple serial based JDM2 PIC Programmer for programming PIC18F chips. The Programmer is powered by the RS-232 port and it works with RS-232 levels at only ±3V.
The programmer is supported by PICPgm and WinPic programming software. Calculates and displays L and C from oscillation frequency using reference components.This instrument requires two precision components: A precision capacitor and a precision inductor. You only need to start with one precision component, either the reference capacitor or the reference inductor, and using this meter, you can select or adjust the other precision component.In my case, I used a pretty high accuracy BK Precision inductance/capacitance meter and sorted through piles of inductors and capacitors to find those that had the lowest error. I then used those parts, a 1 millihenry inductor and a 0.01 microfarad capacitor, in this meter.The basis of this project is several similar projects on the world wide web and some magazine articles before the world wide web was a common means of information interchange. Unfortunately, I am not able to determine the originator(s) of the concept, but I suspect that it is as old as radio.
Another project on my web site, LC Determination by Resonant Frequency Measurement, measures the resonant frequency of an L/C circuit, but the hardware stops at the frequency measurement. It does not proceed to calculate the unknown inductance or capacitance.
To program some AVR microcontroller unit (MCU) you will need an AVR programmer. The better way to do that, is to buy some development kit like STK-500. This kit have the advantage to give you serial port, LCD connector, SRAM socket, 8 switches, 8 LEDs, connectors for all of the ports of MCU and more, to one board. I suggest to beginners, to start working with STK 500 or some else development system, it will help them very much.For the people that are want to program only one piece of AVR, to make some circuit from this site and they don't want to spend money for any development kit, the solution is this ultra low-cost AVR programmer.

We will fix it as soon as possible.PIC Controlled Relay DriverThis circuit is a relay driver that is based on a PIC16F84A microcontroller. The board includes four relays so this lets us to control four distinct electrical devices. The controlled device may be a heater, a lamp, a computer or a motor. To use this board in the industrial area, the supply part is designed more attentively.
To minimize the effects of the ac line noises, a 1:1 line filter transformer is used. This project uses a Microchip PIC microcontroller, a serial EEPROM and a thermistor to create a temperature recorder.The temperature is measured and stored at user programmable intervals; this can be from 1 second to 256 seconds. The time interval is set by programming it and the start time into the EEPROM.Most of the time the PIC will be asleep and the EEPROM IC is inactive. This gives a very low current consumption of approximately 50 uA or about 1 mAh per day.The EEPROM used is 32kBytes which can store up to 32,000 measurements. This could be one measurement every 30 seconds for 11 days for example.The combination of thermistor and analogue circuit gives a range of between about -40 °C and +100 °C although the linear range is between about -10 °C and +40 °C. This project is based on ideas from Rickard's electronic projects page and David B. Thomas VCR Pong.
However, I have developed the simplicity even further, eliminating most of the external components. Using microcontrollers with internal 4MHz clock generator there is no need for the xtal. The 12f675 part also operates on wide voltage range, and the regulator can be removed.For game controller, I plan on using the old Commodore 64 style paddless.
They include firing buttons, which I plan on using as power switch and game reset. 16F675 has a low power sleep mode with 1nA current consumption, so I plan on using that to switch off. This clock timer uses a PIC16F628 microcontroller to display 3 and 1/2 digit time and control an external load. It can be programmed to time from 1 to 59 minutes. The clock includes a calendar with leap year and optional daylight savings adjustments. The timer output can be set from 1 to 59 minutes and manually switched on and off.
The clock also has a correction feature that allows an additional second to be added every so many hours to compensate for a slightly slow running oscillator. The oscillator uses a common 32.768 KHz watch crystal and the frequency can be adjusted slightly with the 24pF capacitor on the right side of the crystal. This is an alarm clock I built.
It was very effective during the sort time I used it, because I programmed it to play a very annoying tune through a speaker. I actualy started to wake up before the alarm went of, so other people int he house didn't wake up from the anoying pitches it played.The Jal sourcecode is available on my download pageFeatures. Timekeeping using the pic's timer0 interrupt. 4x20 hd44780 compatible backlit lcd, displaying the time in big numbers (4x4 and 4x3). Alarm sound tune using pwm.
computer interface for synchronizing time with the web. (maybe battery backup (in case of a power outage.)). The new PIC18F2550 Project Board was designed as the development platform for student projects.The board featuresMCU: PIC18F2550 with external xtal,ADC: one channel 0-2.5V sigma-delta converter, Linear Technology LTC2400/LTC2420,6-channal 10-bit ADC 0-5V,Display: Two connectors for text LCD or GLCD,USB: onchip USB port with type B connector,Power supply: onboard low dropout regulator, rechargeable battery,Code programming: 10-pin header for In Circuit Loader.The board platform is suitable for developing the microcontroller based instrumentation. Students may build the signal conditioning board, plugs it to PIC project board, develops the code and programs it with loader cable easily.
Pinguino is an Arduino-like board based on a PIC Microcontroller. The goal of this project is to build an integrated IDE easy to use on LINUX, WINDOWS and MAC OS X. This is a simple 40 pin PIC development board as described in RadCom for November 2009. It is designed for a PIC18F4550, but it will work with other 40 pin PICs like the PIC16F877A. It has no bells & whistles attached. No buttons, LED, LCD ICSP etc.
All of the PIC pins are easily accessible so that you can add any features you need. This board has been tested with the Vasco PUF and the Pinguino USB bootloaders. For a long time I needed a good programmer pussy, even if it is programming, so from time to time the application gets where it is used. So I decided to build the programmer. I chose between a couple of projects from different authors, but eventually won PICkit2. Microchip released the schema directly in the user manual for the programmer.
On the Internet there are multiple versions of the programmer, it's usually cropped version of the log analyzer features, UART terminal, etc., 12V inverter is a modified version of it and control the MOSFETs, unlike bipolar transistors used in the original design. And it also showed that becomes due to the switching inductance feta leave. Finally, I chose to use the original scheme, although it is quite complicated and the parts used in our country can not normally buy, but my problems with finding parts easily solved. I bought a transistor, the 16F2550 PIC and a few other things, resistors and fry the rest I bought from 'us'. The price is pretty high, unfortunately, moving it around and 600CZK, the main prize and two processor makes the EEPROM.
Below we describe the involvement and put into operation. This is a PICkit 2 MPLAB compatibile Programmer. It is a low-cost development tool with an easy to use interface for programming and debugging Microchip’s Flash families of microcontrollers.
The full featured Windows programming interface supports baseline (PIC10F, PIC12F5xx, PIC16F5xx), midrange (PIC12F6xx, PIC16F), PIC18F, PIC24, dsPIC30, dsPIC33, and PIC32 families of 8-bit, 16-bit, and 32-bit microcontrollers, and many Microchip Serial EEPROM products. With Microchip’s powerful MPLAB Integrated Development Environment (IDE) the PICkit 2 enables in-circuit debugging on most PIC microcontrollers. In-Circuit-Debugging runs, halts and single steps the program while the PIC microcontroller is embedded in the application. When halted at a breakpoint, the file registers can be examined and modified. Here is a very simple project of controlling a small DC-motor (taken from an old personal cassette player) with ATmega8. The ATmega8 is having three PWM channels, out of which two are used here. PWM waveforms are fed to MOSFET (RFD3055) H-bridge.Here, direction is controlled using a two-position toggle switch and speed of the motor is controlled by two push-buttons, one for increasing the speed and other for reducing.The schematic is geiven here (click on the image to enlarge):When switch SW1 is closed, OC1A channel is active which will feed the PWM signal to Q1 & Q4 MOSFETs.
The OC1B pin will remain low keeping the Q3 & Q2 in OFF condition. When SW1 is toggled to open position, OC1A pin will become low, making Q1 & Q4 OFF and OC1B will feed the PWM signal to Q3 & Q2, resulting in the change in the direction of current flow through motor.
Hence, motor rotation direction will change.The speed is controlled by Push-buttons S2 & S3. Pressing S2 will increase the speed in fixed steps. Similarly, pressing S3 will reduce the speed in fixed steps. I believe that the 'JDM Programmer' is cheap and very useful PIC Programmer. However, since 'JDM Programmer' cannot control VDD, the algorithm 'VPP before VDD' is inapplicable.
Programming to the latest device from this reason may go wrong when using CONFIG settings as 'Internal oscillator' 'MCLR OFF'. These devices are given power from the 'JDM programmer',and execute program code. An error may come out by verification, or it may become impossible erasure and become impossible re-programming. In order to solve this problem, I designed a programmer based on the 'JDM programmer.' Since this programmer was made of resistors, capacitors, and diodes, I named this the 'RCD Programmer.' 'Hardware settings' of IC-Prog are the same as the 'JDM programmer.' The PCF8583 is a clock/calendar circuit based on a 2048-bit static CMOS RAM organized as 256 words by 8 bits.
Addresses and data are transferred serially via the two-line bidirectional I2C-bus. The built-in word address register is incremented automatically after each written or read data byte.
Address pin A0 is used for programming the hardware address, allowing the connection of two devices to the bus without additional hardware.The built-in 32.768 kHz oscillator circuit and the first 8 bytes of the RAM are used for the clock/calendar and counter functions. The next 8 bytes may be programmed as alarm registers or used as free RAM space. The remaining 240 bytes are free RAM locations. Here is 0 to 99 minutes relay timer using PIC16F628 microcontroller and 16 character LCD display. The microcontroller is PIC16F628A running at 4.0 MHz clock using an external crystal. An HD44780 based 16×2 character LCD is the main display unit of the project where you can watch and set the timer duration using tact switch inputs.
There are three tact switches connected to RB0 (Start/Stop), RB1 (Unit), and RB2 (Ten) pins. You can select the timer interval from 0-99 min using Unit and Ten minute switches.
The Start/Stop switch is for toggling the timer ON and OFF. When the timer gets ON, a logic high signal appears on the RA3 pin, which can be used to switch on a Relay. The circuit diagram of this project is described below. This is simple to build AVR programmer for Atmel microcontrollers from AVR family. The microcontrollers must support serial programming. AVR programmer is connected to a PC through the RS232 serial interface and can be used with the PonyProg or Avrdude software programmer. AVR programmer is quite simple and it is based on the SI-Prog from the author of PonyProg software.AVR programmer can be used for programming Attiny13, Attiny26, Attiny2313, Atmega48, Atmega88, Atmega168, Atmega16, Atmega8 and it works very well.
I also use the programmer with desktop computer, laptop, with and wihout USB-to-RS232 adapter and it works in all cases. Build a simple data recorder for solar energy lab. The Recorder uses a calculator solar cell as the input sensor and a Multimedia Memory Card for nonvolatile data storage.The device used for measuring daily insolation has been developed. The device was built with a PIC18F458 and the 128MB Multimedia Memory Card, MMC.
The solar radiation is measured by a calculator solar cell. The PIC chip interfaces the MMC using SPI mode.
The interval between samples is set to one minute. The firmware detects the memory card, assigns the file name and begins recording automatically. The LCD displays the file name, current sample and real-time ADC data. With the MMC flash technology and a cheap media card reader, the devices will be able to record huge amount of data and quick data uploading to the PC.
I wanted to share my project of modifying the temperature sensor project and turning it into a thermostat with ATmega168. I added a digital output to drive an LED to 'warm' the temperature sensor when the current (actual) temperature falls below the desired temperature.Two push buttons come in as digital inputs one to ramp the desired temperature up and the other to ramp it down.The logic is simple bang-bang control to turn the LED on and off based on the relationship of actual temperature to desired temperature. It simulates a thermostat in heater mode. The LED is off when the current temperature is above the desired temperature and turns on once the current temperature falls below.
In this tutorial you will learn how to build a simple serial 16x2 LCD display that is controlled via Arduino board by only two wires. The magic behind is done by the PCF8574 chip, an I/O expander that communicates with the micro-controller by using I2C protocol. The PCF8574 is a quick and easy solution to extending and adding output/input ports to Arduino. The chip connects to a standard I2C bus and adds an additional 8 output ports. A total of 8 LCD displays can be connected to the same two wire I2C bus with each board having a different address.
USB AVR Programmer for Atmel AVR microcontrollers. USB AVR Programmer is made of an Atmega8 and few components. The programmer uses a firmware driver that makes this programmer attractive to many amateurs.Another thin why this programmer is so popular is because it is officially included and supported in WinAVR.Once again lets see what this programmer is made off and how to set it up.The core of USB AVR Programmer adapter is Atmega8 microcontroller clocked by 12MHz crystal. Soldered board is ready to be connected via simple USB cable with B type connector (Computer side needs A type of connector).
Resistors R2 and R6 are current limiting resistors, that protect computer USB port. Resistor R7 helps computer to recognize device as LS (Low Speed). Diodes D1 and D2 indicates about data transfer. Header SV1 is compatible with STK200/300 just 4 and 6 pins are used for RXD and TXD (may be used for other purposes).
The MCP9700, MCP9700A, MCP9701 and MCP9701A Temperature Sensors from Microchip offer exceptional performance for the low price. Each have different temperature ratings and accuracy parameters. MCP9700, MCP9700A, MCP9701 and MCP9701A sensors are available in different packaging and are very simple to interface with. Vdd, GND and Vout are all that are required. You should check the datasheet to get a better idea of the parameters for the device you decide to use, though keep in mind that the user module listed below will automatically calculate the temperature depending on the device in use. The meaning from this design is to build it in -i.e.
