ESC Brushless MESA PWM 6i25+7i76

Hmm, looks like I made a custom bitfile for 7I76 with just one 1 PWM per card (where stepgen 4 usually goes)

I forgot to tell, i use 7i92 ethernet board with 7i76 card.

You can probably run your ESC using a stepgen. You need to set it to velocity mode to get a fixed-frequency output to suit the ESC then alter the step-length to give the required pulse length.

However: The pulse-length is a HAL _parameter_ not a pin, so can't be directly connected in HAL. You would need to use (as an example) a custom M-code that issues a "halcmd setp hm2_7i92.0.stepgen.04.step-length NNN" command.

Thanks, I solved with this way. I use fix PWM duty cycle, because this is a braking mechanism for turret on lathe.
