General discussion

Dear all, for a personnal project i try to command the throttle of my vesc with an arduino. I plug on the arduino a DAC that i link to ADC1. Until here everything is fine. But impossible to spin the motor.

With a traditional thumb throttle is working fine. With my DAC is not.. I check i have 3 V in output and parameters ins VESC tool is ok.

Do somebody have an idea of where is the issue? The arduino is powered by the 5V of the hall signal. so i just plug the ADC1 command to the DAC.

Thanks for your help! 

Hey,

I'm new here and have a question: Is there any way to configure the VESC so that it will try to hold the current ERPM while a button on the remote is pressed?
Or alternatively if that's not possible: Can the throttle position be mapped to ERPM? (instead of the usual current or duty cycle control)

Hello everyone,

I have 2 large outer runner BLDC motors which I want to test in back-to-back setup. The setup consists of the motors connected to each other with adapters and a torque sensor in between. Motor A is connected to a 51V battery and motor B has 42V input connected via two different VESCs (SIX MKIV and SIX). The VESCs are connected with a CAN bus.

I cannot seem to find the ID required to implement a heartbeat on our system. We are restricted to CAN protocol only.

This question has been asked and answered,  but something does not make sense at all. 

So I had a cheap normal controller on my DIY scooter with a cheap 1000w 10inch outrunner motor. 

My DIY battery is "rated" by me for 36A. Its a 17S 6p NCR18650 pack. 

So my top speed was 48km/h with the cheap controller.(GPS speed)

I installed my first ever VESC ( Flipsky 75100V2Pro) and WOW. Sooooo smooth and silent. Lots more torture after turning up the motor current way to much. 

Hi, I was wondering if anyone has a schematic diagram of the VESC 75/250, I'm unable to find one myself online

I am using a 3shul vesc CL1000 v4with a sotion mg138d motor with encoder. I'm using a 72 volt 38 ah battery. 

I finally got everything together on my garage built go-kart and soon to be running into a few issues.

1st - when I run motor setup with a generic motor and the large option the detection just times out. I don't do any of the advanced settings but if I try to fill out any of the advanced settings it still does not work.

I am trying to display the current speed on a ST7735S SPI display using an arduino D1 Mini Pro as an intermediary and a VESC FSESC Mini V6.7 Pro. I am trying to follow this video VESC LCD Display - YouTube as a guide however he uses an I2C display what would i need to change if I'm using a I2C LCD display.

Currently building an electric surfboard, Im using a 100/250 VESC, 65161 Flipsky waterproof motor, 18S battery pack (75.6Vdc peak) . Currently redesigning my cooling system and want to use a passive heat sink located at the rear bottom of the board near the motor. The battery pack is in a waterproof case located at the top front of the board for weight balance reasons, this would result in the cables between the ESC and battery pack being about 1.5 meters apart.
