Tachometer problem:
Orginal tachometer has a dutycycle of 33/256 and dont like signals other than that. I run the old open source-code (r027) and I made a sucessful change in it to make it work. but I will upgrade to newest firmware soon..
Is it possible to make a new constant which define the duty of the tach signal in the firmware?
oscilloscope picture of tach signal:
1000rpm 2ms/div
1000rpm 10ms/div
3000rpm 2ms/div
