@Jeremy-Frederick, can you specify which ESC you are asking about?
The PWM pins on the ModalAI ESCs (which have the pwm signals on a connector or test pads) are bi-directional, and yes they could be used as PWM output. However, a firmware change is required and enabling PX4 to send out PWM signals is another change
We were considering enabling this feature but it is not yet implemented. Can you please provide more information about your requirements?
what type of PWM signal are you trying to send ? min/max range, update frequency, (is it one shot, or just preriodic)
how often are you planning to update the value of this PWM signal?
how many PWM signals do you need?
what is the source for the control of PWM signal in your application (RC or something else?). The reason why I am asking, the ESC would need to receive a serial data packet from voxl_esc driver in px4, so somehow that pwm output information would need to enter the voxl_esc driver.
