Paul i noticed you have tracked the board for an icsp port. Can i build a cable and program the device in circuit? If not i can build up a simple programmer on a piece of stripboard like this:
AVR Programmer
I think my problem is the starter is not drawing enough current to cause the micro to recognize the lem so it just keeps increasing the pwm duty. I have another monster forklift motor that i call the "warp13" which i'll use for the next batch of experiments when i get the more powerfull igbts. That will draw enough current.
I am quite good at pic micro assembler code just never made the leap to c. Are the atmega devices flash or otp? The clock is ticking!
