Problems Compiling Firmware

Submitted by LB94 on Tue, 2022-11-29 00:08

Hi,
I have been working with the VESC project for a short time and now I wanted to write my first own application. For this I followed all instructions of the Readme (https://github.com/vedderb/bldc) to compile the BLDC firmware on my Windows PC. However, I get the following error message every time I type 'make fw_60' or 'make 60' to compile the (original/unchanged) firmware:

VESC Tool Reporting RPM Different from Scope

Submitted by bayetan on Wed, 2022-11-02 15:39

Hello All,

I/m running VESC FW 5.02 and FS Dual 6.6 with an ABI Encoder on motor with 21 Poles.  The eRPM reported by VESC Tools is about 60 eRPM higher than value measured using a Logic Analyzer (using period of the Index channel).  That ~60 eRPM difference remains at higher RMP as well.  And the "Sensorless ERPM" on the Encoder Tab is set to 25,000.  I realize that's a small difference but I'm trying to control to very small speed and would like to know if anyone can get me some help resolving it.

eRPM reported by VESC Tools is 8000 eRPM

DRV835x

Hello, I am looking to design a VESC board for a Onewheel. I am trying to follow the VESC_6 schematic as best I can, but due to part shortages and the high voltage of a Onewheel battery, I have to make some changes.

The most major of which being that I cannot use the DRV8301. I noticed that the DRV832x is supported by VESC, does this mean the DRV835x is too? As they are basically the same chip with different supply voltage ratings?

Thanks!

Dual motor control on VESC6 / 6.00.58

Submitted by jediengineer on Mon, 2022-10-10 19:21

I need to be able to control 2 motors simultaneously using VESC for an RC vehicle. I'm currently using an STM32F407 and VESC firmware version 6.00.58 to do this. Right now, I can get one motor at a time to spin, but I can't figure out how to get both to spin simultaneously at different speeds or directions. 

The software has a flag for enabling dual motor support, and we can control two motors, but not simultaneously independently (simultaneous run, independent speed/direction). Based on that I designed around the STM32F407 using the VESC6_Plus schematic.

Cruise Control Questions

Submitted by piopi0 on Sat, 2022-09-24 03:56

I'm running a VESC6 on the V5.3 firmware. My throttle is set up as "ADC + UART" and I am using "Current no reverse Brake Center". According to this post I should be able to use a button connected to PPM to use control cruise control. However, despite trying pull-up and pull-down button configurations connected to PPM I've had no luck getting the feature to work.

Does anyone have any information regarding the feature? It seems like support may have been removed in newer firmware or limited to the NRF controller?
