Sorry Mattaus, I didn’t want to sound like I was disagreeing with you. Any questions I asked were not rhetorical, they were because I want to know! I’m mystified by the failures. Am I correct in saying that the buck driver should not be damaged by an open circuit condition?
1) I think we can use the prescaler to easily set PWM to 150Hz or 300Hz.
2) MiniDRV does not have LVP, would you consider JonnyC’s firmware ?
3) OK
4) OK
5) OK, don’t need EEP file though
x) do you want an e-switch firmware or a clicky one?
