Hello, I am looking into VESC as the base hardware and firmware design for a 4 in 1 ESC PCB for use in a custom quadcopter. I have designed BLDC ESCs in the past that used propreitary firmware. I like the open source nature of the VESC project.
I would like to know what I can slim down on the hardware to fit 4 ESCs on one board. Can I drop the current sensors for the 3 phases?
Hi,
All I know is that the mcpwm_foc_hall_detect() function is used to calculate the initial Angle of the sector corresponding to the HALL sensor. The results are stored in hall_table[].
For the details, there's something in the code of mcpwm_foc_hall_detect() that I don't understand：
//--------------------------------------------code section-----------------------------------------------------
// Forwards
for (int i = 0;i < 3;i++) {
Hello, I am new to VESC and currently have troubles controlling my VESC with the CAN-BUS. I am using a sparkfun CAN-BUS Shield connected to an Arduino to send CAN messages to VESC for it to move the FOC motor.The arduino is able to send CAN messages to the VESC. On the VESC tool, the CAN analyzer idicates that the VESC is receving the CAN message. However, the motors don't move at all. An example of a CAN message I am sending over to the VESC is:
Extended ID: 0X00000900 , Data: FF FF F1 A6 0 D 0 B4
Hi,
i have a problem with Vesc 6.0 mounted on cablecam. After some time (havent understood why yet) the Vesc doesnt send anything ro motors.
i am controlling it through serial port and I am using VescUart library. I send Duty Cycle command and I read all the parameters.
When the Vesc stop working (no more motor control) it still gives me temperature readings through serial port.
I tried to connect Vesc Tool runnung on PC via USB-c and if I send reboot command it start working again.

Hi Guys,
I'm working on a robot project and plan to improve the torque control function by adding inertia to the control system, as my understanding, the accurate output torque should add the acceleration * inertia part. and i have to had a stabled speed signal to get the usable acceleration signal.
Hola alguien puede ayudarme en español gracias tengo varias preguntas
I see that VESC is CAN enabled, but I cannot find much (any) information regarding the CAN protocol on this websites documentation section. I apologized if I've missed it!
Hi, I'm trying to get the wheel speed over CANBUS - I have a Trampa Vesc 6 mk5, with an Ozo BROU-AGRI-2019 wheel. I can see that the CAN_PACKET_STATUS message has RPM but
this doesn't seem to tie back to approx speed (measured using a stopwatch and wheel radius!), even after accounting for the detected gear ratio.
Please can someone help explain what I'm doing wrong...and if there's an easier way of getting speed data out through the CANBUS?
Secondly, is there a way of getting Hall sensor data out through the CANBUS?
Thanks!
Hey all,
New to VESC, I'm trying to use two hoverboard motors with my dual vesc 4.12, motor detection seems to work mostly, however the motors vibrate and don't spin. , my settings look comparable to others I've seen online, and the motors work fine on the stock motherboard.
But when I try and co tell them either with forward / back buttons in vesc tool, or with pwm signals from my RC remote, they just make a horrible noise and sort of vibrate.
Attached is a video of what manual signals sound like:
