I have HW 4.12 SW 3.40 VESC from maytech.
using it with pxhawk, I, controlling it with PPM signal, the vesc and pixhawk looks OK, but the signal read at VESC is not correct.
the px4 is sending 1.5ms(checked it.)
but the vesc is reading around 1.3ms~
I can change the start and End value, but the real problem is that
I want to control 3 vesc with 1 pixhawk output pin, and it changes when I connect multi VESCs.
anyone can guess why this happening?
> check when the BEC 5V IN is connected, not connected, only one connected.
(or maybe someone know how to modify the px4 firmware)
Always use CAN, never Y-PPM. Make sure to start up your VESCs simultaneously to avoid that the CAN chips will fry. They just need to be connected to the same power source / switch.
Y-PPM causes ground loops!
