VESC Firmware

Just as a heads up, we created a pull request to add our virtual motor support code.

With our virtual-motor branch you can engage a virtual motor using the vesc terminal and start playing with it.

More info and fancy screenshots in the Pull Request

Maybe someone finds it useful and can't wait for Benjamin to review it.

Hi,

I already mentioned one issue here: https://vesc-project.com/node/859

EDIT: NVM there are additional issues with the timeout code. There are several wait loops that will fail if the WDT is never initialized, those also need ot be commented out. Mod can delete this.

Hi,

I have a Flipsky 4.12 hardware based mini VESC. I did a git pull on my clone of the bldc firmware repo, and then changed the configuration files to uncomment the following:

> #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

When I load the firmware, however, I have no USB VCP. 

Any ideas what might be wrong? Did I miss a source config step? If I use hardware 60 I do get USB VCP, so I know the board is fine.

Hello,

I'm currently trying to develop a 60kW motor drive for Emrax 188 motors. I'm in the very early stages of the design process, building a basic block diagram and researching specific part numbers. I've taken a majority of my inspiration from Marco's 150kW VESC design.

Dear all,

i have a Problem with a custom app and FW 3.53:

This is the Custom app Thread

Hello everyone,

Does the firmware support standard CAN where the id uses 11 bits? It seems that the comm_can.c file uses "comm_can_transmit_eid" and never uses "comm_can_transmit_sid".     
 

Hi All,

I am currently using the VESC in a robot application which uses mixing to control the steering. The issue I am having is on standard remotes the mixing method basically makes the corners go beyond 100%. This triggers a failsafe on the VESC as the pulse is out of range causing the robot to stop.

I am trying to modify the app_ppm file to mitigate this however I am unsure where this is contained.

From reading the source I thought this section would be responsible for limiting ranges in servo_dec.c.

Hello folks,

I'm new to this forum and before asking my question I'd like to say that this project is amazing.

I am planning to control a PMSM with 5 pole-pairs.

So if I want to have 20000RPM (for example) I'd need a sine-wave of (20000RPM*5pole-pairs) / 60seconds = 1.666 kHz right?

I was wondering, where I can find information of the maximum possible sine-wave frequency (or the therefore needed pwm-frequence of the fets).

Does anybody have a link / hint for me ?

Thank you!

Dear Guys,

we build a self balancing Scooter with 2 brushless motor and control them with 2 VESC.
We control the VESC with an Arduino Mega over PPM signal. but now we facing some problems. 

I need continuous incremental position control for my robot. I'm using this fork of vesc-FW, where tlalexander, raess1, and greymfm have added support for position control with AS5047P absolute encoders.
