To convert voltage levels from microcontroller from programmer to the programmed microcontroller we use 74hc Here are three archives containing hex-files and drivers for Windows. So, just build it and load one of three firmwares. Adding check value of target cell memory in word mode isp. Anthony Van Herrewege Rating: Inversion sequence actions give the same error too.

When J3 is short the frequency is 20 kHz, when open – A new Com port will appear, check your Device Manager. I used a low current LED diode with a 1k8 resistor, if you will use standard diode, you shuld use a lower value resistor.

Programming microcontroller We need another programmer to programme the AVR in our programmer.

You might need the “low frequency” programming when internal oscillator of the controller the one you are about to program is set to kHz. He adopted those three firmwares for one hardware. Oleg maintains no homepage for the project.

To use it with Arduino go to Anthony Van Herrewege Rating: New USB device strings: In any way target program work is right. I’ve already written about USBasp, so I’m not gonna do it again. The microcontroller is clocked with 12Mhz crystal with 22pF capacitors.


The image on the left is Oleg with his paraglider, he contributed this example project: An Arduino compatible prototyping board, so simple that it can easily be built on breadboard! But programming and verification only one tool always OK.

On pin 9 is a CLK signal, that can be used to programme the microcontrollers with the fuse bits set to external clock. Finished programmer The microcontroller requires a socket, so we can programm it if we fail in first try like I did or for a firmware upgrade.

Change the name also URL address, possibly the category of the page. If you want to discuss contents of this page – this is the easiest way to do it. Something does not work as expected? Reset pin is pulled up to 5V with a 10k resistor and protected against interference with nF capacitor. The Printed Circuit Board for this programmer is a quiet compact one sided board.

Edit History Tags Source. I aavr make the PCB, why should I? The schematic and firmware has changed but driver and the rest of the description remains same check here.

Once the microcontroller of our programmer has been programmed, we can finally use our programmer. Remove it after loading and place jumper J2.

Append content without editing the whole page source. So any program should support this programmer my gues. So, just build it and load one of three firmwares. It can be used to program devices such as CPLDs.
