Hi,

I am trying to port VESC firmware on STML4 controller with more recent version of ChibiOs.

I am using STM with frequency of 120MHz with one ADC which can work on 120MHz,  I am using only foc control and have an issue with current control and current measurements.

When I try to start motor with current control current is constantly increasing until ABS_OVER_CURRENT fault is triggered, also when I start motor with duty control and turn on real time data motor current is fluctuating a lot.

My team is currently using the new VESC hardware at UC San Diego for autonomous vehicles. We're collecting training data by driving around a track with donkeysim, and we've been running into this issue when attempting to make turns from time to time. This is the error that comes up when the donkeycar software crashes.

Hi again!

Hello,

(not beeing an expert in this topic,)I am currently working with a already given setup of two single Flipsky FSESC4.12  with 50A connected via CAN-Bus (parent child compound) to power a electric skateboard. There is an implemented inertial measuring unit that sends acceleration data to the parent via UART for further processing. Additionally, I have a Bluetooth low energy module connected to the child but it was only used for setup reasons since now.

Hello,

My friend and I are students at the University of Michigan and we are trying to create an electric longboard for our embedded systems class. We have decided to get an off the shelf VESC for our project and are having some issues determining whether or not we will be able to interface with one. For some context, we are working with a budget of $1000 dollars.

Hello,

Im working on my dual boat motor for my fishing boat. Yesterday I connected the motors for the first time. The motors in Flipsky 65111 and ESC is FLIPSKY Mini FSESC6.7 PRO 70A.

I have run the FOC wizard and it detect the motor and everything is working. However at low RPM the motor runs pretty hard and it is impossible to run it at low rpms. See the video:

Is this expected or can I adjust anything?

Hello,

I am using the Spintend VESC 75/100 v1 (FW 5.3) on an escooter.

I drive the VESC with an ESP32 APP with CAN bus. It uses the COMM_SET_CHUCK_DATA message at 30Hz to give orders (so, little delay).

It works really great... except one thinkg (sometimes scary) : when I press full brake, it never react the same way.

Sometimes, it brakes strongly & instantly, sometimes, there is a delay (~200-500ms) with really low braking force (even if brake is pressed at max during this time), then it apply full braking force.

Hello VESC Community!

I'll take my chance today :)

I am looking for a co-founder for a project related to VESC-based controllers.

Hey yall,

I'm trying to set up this ESC (link) with two motors. I have this flipsky remote connected to one of COMM ports over UART. I'm only able to get it to control one motor at a time (depending on which side of the ESC i plug it into) but not both. 

Hello, 

I am new to brushless motor control so forgive me if my question is incomplete or basic. I am currently building an autonomous race car on a 1:10 scaled car chassis. I am wondering if I can use 2800KV sensored motor with Vesc6 Edu for rpm control. 

My robot has:
