To be honest, I haven't programmed any drivers yet either. Though, today I received my AVRISP MKII programmer from DigiKey. Maybe this weekend I'll try flashing the program from the thread I linked in my previous post. The driver I'll first try this on is a NANJG 105C with 8x 7135 linear drivers (2.8A @ 100%).
The driver from this thread uses 4x 7135 linear drivers (1.4A @ 100%) and gives 5%, 30%, and 100% outputs, which I think would be pretty good for general use. It also looks to be an Attiny13A, which could be reprogrammed in the future.
