VESC Firmware

Hi, I'm trying to modify firmware to hold position of motor when duty cycle is below 10%.(FOC with AS5047)

I am a mechanical engineer, so I'm not sure where to begin.

First, I cloned original bldc folder.

From mcpwm_foc.c 

Original code

Hi,

I was trying to upload a customized firmware(simply adding servo ouput from can-bus signal) on my VESC6 mk5.

I followed the instructions from bldc github (https://github.com/vedderb/bldc).

I tried both vesc_tool_3.0 and vesc_tool_3.1, but the results are the same "The selected file is too large to be a firmware."

Does anyone have the same problem? How do you solve it? 

Not sure if this is the right forum, and I'm getting ahead of myself here as I've not even powered on a single controller.  I have the fsesc 6.6 based on a stm32f405.  Rather than a skateboard though, I'm controlling a dual motor device with a dynamic moment of inertia.  (Sounds cooler than it is).  I want to adjust the commanded speed on the fly based on the angular position and the statically changing moment of inertia, thus giving me a constant angular momentum mode.  

I am running a VESC6 MKIV from trampa board with the app mode in ADC and UART mode.  I have connected an arduino to read (and log) data from the VESC, but UART communication is failing.  No matter what I try, the VESC is only sending 0's to the arduino data.  Does anyone know how to fix this?  Thanks!

Hi everyone,

I am testing a BLDC motor with VESC HW4.10 hardware version. I am flashing the firmware Version 5.03 into VESC using openocd.

Problems are

1. Motor changes it's direction when the throttle is rapidly rotated from zero to higher value. No problem occures when the throttle is taken smoothly.

2. When the throttle is held at very low value, motor vibrates but does'nt rotate. when i monitor the Rotor position it changes rapidly from 0 to 360 degrees as it changes when motor runs properly.

3. Motor starts with a jerk.

Hello. I had some background programming in embedded systems, but I'm new to VESC programming. I've done an application very simple, but now I plan to make an application more complex, so debugging is a must. How do you debug an application? There is a dev tools console in VESC-Tool, and communications via USB between VESC and VESC-Tool, so the printing should not be an issue. How is it made? How can I print from VESC application so the result is written out in VESC-Tool console??

Thanks in advance,

Diego

Hello,

I am writing my own application in C++ for running Trampa VESC 6MK V. In my program, I manage to integrate functions for running motor and reading parameters, but I can not integrate function for writing motor configuration from default XML file. 

What I did, I took and connected function (from vesc tool) in next order:

I am currently working on a winch with multiple ESC. As I need to go forward and backward, I send positive and negative commands over CAN to VESC. to go forward, no problem.

Problem is for backward motions, it does not works really well , the motor can go backward but with it's maximum allowable current... Does somebody already face this issue? How does you solved it ?

Would someone have a link for me?  New to this.  Im using the newest mac version, just bought it last week

Hi, I have a question, is it possible to upload a vesc to the motor driver which is based on stm32, it only has measuring resistors that measure the current from the battery, how does it look with uploading such a software, is there any pinout to define for it to work? Any of you guys tried something like this? Controller: Sabvoton ml60 in the programmable version, of course. Thank for answers!!
