VESC Firmware

Need fast start fast acceleration firmware 5.2 how to change?

Hello,

I am working on a project to control the VESC from a Arduino (ESP32).

I am controlling it in current mode.

I'd like to control the acceleration force (FOC current PID Ki/Ki) from the UART.

but ... is it possible to control it from UART ?

A quick study on the VESC code, it doens't seems to allow that.

Any idea ?

Thanks !

Hi, I'm using vesc50A for my robot project using CAN communication.

When I get the tacho_value from CAN status (config. CAN_STATUS_1_2_3_4_5), sometimes data doesn't updated.

I'm reading the CAN status data 50Hz and the "CAN status rate" of VESC is 50Hz. The motor has 10pole, and 5.4 gear ratio, Hall sensor.

Hi, I'm new to VESC. I am thinking of using VESC in my robotics application. Up to this point in time, I've been building smaller robots (~3 to 5 lbs; ~1.6 to 2.4kg). I've been using BLHeli32 ESCs which (as most here already know) were developed foremost for the quad-copter community.  I now want to build larger robots and need sturdier/larger ESCs and motors.  In my application, I have a need to update the ESCs at a very high rate. The BLHeli32 ESCs have a protocol, dShot1200, which I've been using, and this protocol can support update rates as high as 32kHz.

Hello, I've been searching for some documentation for the vesc source code, but to no avail.

I've been digging a bit through the functions in mcpwm.c like the ISRs and the like, but without documentation it's hard for me to understand their purpose / use.

Is there any documentation online that im missing regarding the code (maybe even just a design of the software / flowcharts etc..)?

Appreciate any help there is! thanks :) 

When I use file https://github.com/vedderb/bldc/blob/master/build_all/100_250/VESC_defau... for firmware update through VESC tool, everything works fine.
But when I make build on Windows or Ubuntu and update firmware with my file from /build_all/100_250 folder, connection error happens and then I restore VESC through ST_LINK.

I think something wrong with build, what it could be?

Need firmware for hardware Flipsky v4.12  50A first update firmware after bootloader or no?

Need help please¡¡¡

Correct firmware?

Many thanks¡¡¡

Hi All,

After flashing the latest firmware 5.2 to my self developed board, I do not get a connection to the USB port.

Interesting enough the USB port comes alive only after I send a few messages over the CAN Bus.

Initially and after power off/on, the red en green light flash twice each 2 seconds. After sending the CAN messages, the green LED is lit, but very dimmed and the red LED flashes twice each second.

After this I have a "ChibiOS/RT Virtual COM Port" available and the VESC Tool connects to the drive over USB.

Hi, i have a old 4.12 vesc. The vesc works since 2017 with FW3.29.

Today i want update to 5.02. My steps below (Ubuntu 20.04 & STLinkV2:

git clone https://github.com/vedderb/bldc.git bldc-firmware

Edit conf_general.h ->
#define HW_SOURCE "hw_410.c" // Also for 4.11 and 4.12
#define HW_HEADER "hw_410.h" // Also for 4.11 and 4.12

make upload

** Programming & Verified OK **

But now i cant connect to the Controller.

Hi, my vesc flipsky 4.20 dual has 5.1 firware, all work OK. Now installed 5.2 or having problems with one of the engines, my question how can I reinstall 5.1 from my phone app, thanks
