BS 40A - Motors "hammering"

[ashankaei]

Hi,

I tried to flash the Blue Series 40A, with bs40 and bsnfet and they both have an issue. When I turn on the motor(s) they do some sort of hammering as if they want to go CW and CCW in different cycles.
I checked my wiring and used different ESCs, Motors and Batteries they look O.K.

My guess is that, the phases are not following each other but I'm not 100% sure! Did this problem occurred to you before?

Hello! That sounds mostly like perhaps the wrong pinout. 40A is likely not bs_nfet but is likely bs. Did you get this working in the meantime?

Had the exact same issue with bs40a today. With bs_nfet I could hear the FETs switching but the motor was not running at all.

@sim- Are you referring to the XnFET and XpFET pins?

@ashankaei @sim- Turns out the pins are different. Here is a fix #128
