I have soldered MPU 9150 onto my ESC - How can I confirm that it is working?

Submitted by delond on Sat, 2018-07-14 15:05

Hey,

 

I have soldered the MPU 9150, but because of the footprint of the chip it is impossible for me to know if I soldered it correctly. What would be the best way to test it. Is there a function in the VESC tool that will help?

 

Thanks

FOC and very low speeds

Submitted by verbeek on Mon, 2018-07-09 16:17

I try run a BLDC motor from a hoverboard with VESC. My challange is to run the motor very slow, about 10rpm.

I started with FOC using the integrated hall sensors. Fine but it is not possible to rotate the motor really slow.

I attached an AS5047 encoder because I thought that the resolution of the hall sensors is probably not sufficient to let the speed PID controller work properly.

With the AS5047 is see the following

setting duty cycle to about 12% (no PID) rpm is swinging between 600rpm and 800rpm.

I have a mountain board with trampa motors 12s battery and trampa Vesc going off-road ie a golf course lots of grass making the setup work much harder than on tarmac the motors get hot and leave me standing still ,is there settings I can adjust with the Vesc tool to prolong my ride time on the golf course and other off-roading or should I stick to tarmac

can't communicate with arduino nrf

Hi!

I an trying to send command to the Vesc6 via the built-in nrf chip with an arduino+nrf. With the following configuration on vesc and arduino,  the vesc receives nothing.

configuration :

power : 0dBm

speed : 1mpbs

crc length: 2 bytes

no ACK

retry delay 1500us

retries 5

address : 0xc6c700.

does someone have an arduino code working for this setup vesc> nrf+arduino ?

I want to etablish communication even with arduino as receiver and vesc transmitter.

Thanks!

 

 

Motor only running in reverse

Submitted by obex_mike on Mon, 2018-06-25 16:25

Hi, I've got a Trampa mountain board with 136kv motors, vesc6's and 12s zippy batteries which I've just set up. Due to lack of a CAN cable I'm just setting up the 1 vesc for now. After much confusion I've got the motor and controller configured (sort of) but when I accelerate the motor is just running in reverse. I've tried inverting the motor direction in the app but this has no effect... can anyone help?
