Hi,
would anyone want to help and write a program for a high voltage programmer that will work on the board provided in the attachment? I made this board based on the work from Kai Bader, and the sketch included is an example based on the work of Paul Willoughby.
Reward is either 5 printed circuit boards made by Elecrow or one fully populated and tested board made by Elecrow based on this schematic.
Looking forward to your replies,
Erik

So, you're making something like this?

Similar but with a difference: my project is a Arduino shield too, but with 5 sockets. The full range of ATtiny (85/45/25/15/13: 8pin, 84/44/24:14pin, 26/261/461/861: 20pin, 2313/4313: 20pin too but different pinout, and the ATmega328: 28pin.
It is based on a project by Kai Bader, but since he has no time to finish it we agreed I could make a pcb; the programming is nowhere yet so therefor my request.
Rgds,
Erik
The pcb layout is not final: any changes required by software can be implemented. For example I had provided MISO, MOSI and SCK to be interconnected. If however other pins are required for example for SDI, SII, SDO and RST then the hardware can be changed.
