UART Accel/Gyro/Mag data

Hey everybody,

I've looking for a solution to obtain the accel/gyro/mag data from VESC using UART on a linux machine

At the moment I can see needed values using VESC tool in IMU Data using com port, but when I am trying to read this com port without vesc tool - no data at all

I've found several similar subjects in the forum, but no clear answer

 

Thanks in advance,

Help calibrating a hub motor

Submitted by Tin_Man_0 on Thu, 2019-12-26 01:17

I have an ebike hub motor, direct drive, and for some reason the wizard isn't calibrating it correctly. It sounds like a Harly motorcycle engine when running and has no power or speed. I know next to nothing about these types of motors, or electronics for that matter. I've attached some screenshots of my manually and slowly rotating the wheel. I can put ones of it running "full speed" if that's better. From looking at the charts, I suspect something to do with the rotor position or the sensors might be off...

Position control with Hall and A/B encoder

Submitted by jo.rauchfuss on Tue, 2019-12-17 04:12

Hi all

I am trying to control the position of a valve, using a BLDC motor with hall and encoder(A/B) feedback.

The Motor needs to turn 26 revolutions from Closed to Open valve. There is no absolute sensor on the motor, only relative A/B encoder and end-stop, in each outer position of the valve.

I can spin the motor without any problems, but I cannot get position to work, I feel that the documentation is lacking some information about this subject. I see that multiple people got it to work on Youtube, but they are using different sensors.

Two VESCs with servo-out firmware

Submitted by _saeed_arabi_ on Fri, 2019-12-13 22:22

I need your help. :)



For a robotics project, I want to use two VESCs to power two motors. I also need the VESC ​flashed with the servo-out firmware since the steering of the robot will be controlled using the PPM cable of the VESC. My plan is to first flash both of the VESCs with servo-out firmware, then assign a slave mode to one of them and finally connect them via canbus cable. Then, connect the master VESC to the onboard computer of the robot. Does this setup work?

 

Thank you for your help. :)

missing Analog Throttle failsafe

Submitted by bosko on Thu, 2019-12-05 16:47

Hello,

im user of VESC 4 and here is my setup.

im using ADC + UART

I use Analog Throttle (ADC1 , 3.3v, GND)

I use Bluetooth (5v, GND, TX , RX)

When i power VESC all is good, motor spinning, but when i remove Analog Throttle from VESC, motor rotate with FULL SPEED.

Is there any FAIL SAFE for that ? 

I want to STOP MOTOR if i remove Analog Throttle jack not to FULL SPEED.
