Setting PID gains (and other config parameters) over CAN Bus

Submitted by TheCuriousRobot on Thu, 2022-12-15 22:03

Hi,

I'm using 3 VESCs for a 3-wheeled driving robot, and have all of them wired up over CAN Bus.
For configuring and setting parameters with VESC Tool I am able to use a USB connection into only 1 of the VESCs, which detects and writes all of the parameters over CAN to the others

For control, I have an STM32 board that sends speed and position commands to all 3 VESCs over CAN.

VESC and T500 Thruster - Problems obtaining right speed

Submitted by SIGURD on Tue, 2022-12-13 13:45

Dear all,

I hope that someone can help clarify some things for me regarding the use of the VESC. 

I am using the HD60 VESC and the newest firmware (6.0). 

I am powering it at 24 V from a mean well DPU3200 power supply.

I am using the VESC for an ROV project where I would like to obtain some feedback from the ESC, this is provided by the VESC, which also allows me to use CAN as communications which is also preferred. 

Balancing Throttle

Submitted by kstuck on Mon, 2022-12-12 22:31

Thanks to everyone who makes the VESC possible.

It never ceases to amaze me the things I find that a VESC can control and the commnunity around the VESC project is amazing.

I was wondering if there been any thought to adding throttle control in balance mode?

This is not needed if you are doing a one wheel type skateboard but makes thing much easier if you are building larger diameter balancing wheeled vehicles that you sit on and ride.

Kill Function - Analogue Input

Submitted by austrobots on Sat, 2022-12-10 12:19

Hello. I am intending to use the analogue input as a kill switch for my VESCs. I was hoping to pull AD1 low with a 5k resistor to ground an then enable it with a 5V input from an Arduino (via a safety lanyard switch).  I can not see in any documentation what the "high" value is for the analogue input. Will 5V be high enough to pull it "High"?
