VESC Original Hardware

Hi! I designed VESC6 MK5 custom board using VESC6 MK5 schematic and all functions work well without any problems and both VESCs use 5.3 version Firmware.

But I tried to control two same boards using CAN communication but I cannot communicate two boards using CAN communication.

It seems the master VESC6 MK5 cannot find the slave VESC6 MK5 when I scan CAN device using VESC tool, I use VESC tool 3.01 version and it shows local CAN device only.

Problem Summary: Using Trampa VESC75/300 in a heavy robot that needs to be able to operate at temperatures down to -20C. Below about +20C the VESC will not run the motor smoothly at high torque/low speeds for some period of time after the VESC is turned on. For 20C this lasts about 1 minute. For lower temperatures this can be many minutes of poor performance making the robot drive very badly. Once the system is warmed up it functions smoothly with great torque and power.

Hi,

I am creating a (FOC-)model of my VESC6 driven RC-car in simulink. My simulated responses are not yet the same as the physical responses of the car (the simulation reacts slower). And now I am wondering wether the the PID gain values as displayed in the VESC-Tool are for a continuous-time or discrete-time controller. And if they are for a discrete-time controller, which sample frequency is the VESC6 using?

Currently I have copied the PID gain values from the VESC-Tool to continuous-time PID blocks in simulink.

Hello friends, I'm new about VESC and as you can see from the topic I've been struggling about getting RPM data from the VESC 4.12. I want to get it via UART and my receiver is a STM32 MCU. I couldn't see any examples that I can follow about STM32 (there are some examples on Arduino). So can you suggest me any solution about that?

Hi everyone, we recently got our VESC 100/250s in and I can control our motor through the VESC tool just fine. I've been trying to find some information on how to send commands to the VESC over CAN but haven't had much luck. I tried to mimic what I saw online from a couple of different projects but to no avail. (https://dongilc.gitbook.io/openrobot-inc/tutorials/control-with-can, ht...).

Hello Makers,

I found original 100250 could handle only 180A in a hot day. I have ventilated cooling with big radiator..

To improve performance, I milled copper block...

Hi all,

I intend to connect an AS5047 encoder to my VESC 75/300. The baseline connection is clear to me, however, I have some questions (don't want to risk to burn my VESC):

- is it mandatory, to swap the resistors R1 and R2, if I want to connect it with my VESC? I found a description, where it is stated, that for the 3.3V operation voltage, the VESC has, R2 has to be populated and R1 has to be removed on the AS5047 pcb. Is this really mandatory or only optional for higher accuracy?

Hi guys , I've one answer. 
I've seen the schematic for vesc 75300, but anyone know what upgrade that schematic need for support 20s? 
The original chip INA240 can support max 75v I've seen, any solution? 

In the documentation section there are links to the VESC ESC hardware reference designs. Is there an existing BMS hardware reference design? If not, I would like to work on developing one.

The software repo description lists EXACTLY What I would want to add to a BMS. https://github.com/vedderb/vesc_bms_fw/blob/main/README.md

Hey Guys,

I just started my journey into the Vesc universe with a HD-60 and my first setup on PC Vesc Tool 3 is running good so far. But form the start I was wandering how can I connect to my Internal Bluetooth. I simply cant see it using the scan Button on my Vesc App ( using Androit 11)
