I have Flipsky 75100 75V 100A controller, and reverse button there works something strange - it does not reverse, just slows down rotation. And problem is that this issue is inconsistent: when VESC is connected to USB, reverse button works as usual.
here is video with demontration of the problem.
It turns out that this bug is only with "Duty cycle Reverse Button" mode. Looks like that Duty Cycle has this problem. With "PID Speed Reverse Button" I see, that there is sometimes some forward movement in the very beginning of REVERSE ENABLED move, but then it starts to reverse, but in general it works much more better. Still, I had some time tuning parameters of PID, throttle curve etc.
