Hello,

What i need is to programm 10..20 pcb´s with atmega88PA-AU simultaneously via ISP interface, how to that?
I have the Diamex ISP programmer. Can it work if i connect all ISP of the boards in parallel?

Best regards

By the time you posted this, you could have done it on single programming!
Communication would not be OK and you probably overload your programmer.

Hello hgrueneis,

At the moment I program every pcb "Atmega88" one after the other
My question is for a future, if i have to programm a higher quantities of pcb's. Is there a way to programm trough ISP up to 20 micros at one time, i don't want preprogrammed controllers

Regards

Because the programming devices have a communication to the MCU to be programmed, there is no way to program 20 (or two) in parallel. Communication between chip to be programmed and programmer would collide.
If you want 20 to be programmed at a time, better get 20 programmers!

PS.: unless somebody has a better understanding of it!

The only way I can think of a solution is following.
Have 20 programming plugs, which you can switch electronically with a multiplexer and program them one after the other. You would still have to see if they verified correctly.
