Re: Motor doesn't spin, only squeaks (FOC with encoder)

C5, C6, C7. Thanks rew

And for the resistors ? I guess I should remove R8, R9, R10 and leave the pull-up resistors..

FOC in speed mode + FOC with encoder

Hi guys, I am trying to control a brushless motor of a robotic arm with the VESC. I am stuck with some problems, I would love to have your help and feedback on where I am now. 1) The FOC control (sensorless and with hall sensors) does not work in speed mode. I have segmentation fault everytime I lau...

Re: Motor doesn't spin, only squeaks (FOC with encoder)

Hi Christian,

I am stuck with a similar problem. So I would like to know :

Which capacitors and resistors (# of the components on the attached schematics) did you remove to make it work ?
Did you do other hardware changes to make it work ?

Re: Impossible to flash

hey rew,
thanks for your reply.

I actually flash a kinda blank code into the VESC with cubeMX using a STLINK, and I should have toggled some IO pins.

Now I use STLINK to flash the VESC program but that does not still work..

Have I toggled some pins that disable flashing it again ?

Impossible to flash

Hi guys, I recently wanted to try a personal code on the STM32 of the VESC board, so I flashed an "empty" code on the STM32 generated with CubeMX and Keil-uVision. Now, it is impossible to flash the bldc-firmware back. Is there a chance I burnt my chip ? Is it possible to flash a code wich...

"Encoder support is not enabled"

I have a brushless motor with encoder specially made for electric skateboards and I want to control it with the VESC. I downloaded the bldc-firmware, bldc-bootloader and bldc-tool, and followed the whole tutorial. But I am stuck with FOC control with encoder.. I followed the youtube tutorial of benj...
