VESC Firmware

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.

Hello,

I am having trouble updating my original VESC 4.12 to a newer Firmware version (desired version is 3.31).

In short: Updating the firmware over the VESC-tool or through flashing the newer firmware directly on the chip with an st-link, results in no led blinking and the VESC not being recognized as USB-device and consequently not being able to connect with VESC-tool -> basically bricked.

Information soon
