hello guys

im not very good with programing

I built for my son a custom ride on car powered by flipsky vesc 6.6 plus with 2 x 3250w motors . it runs on 24v batteries for now

i need some help programing the vesc. i probably need a custom firmware or something

the car needs to run PPM and ADC for safety reasons or at least switch betwin them without having to program the input every time thru a switch

Can any one help me with this? i am happy to pay 

i think someone over on the skateboard forum is requesting some mods to the current control mode and i think it does make a bit of sense but requires some tweaks.

basically they still want current control, but when they apply 50% of throttle they don't want the motor to turn more than 50% of no load speed, but they also want the motor to coast as they release the throttle.

i think it can be done in current control if the % throttle not only sets the motor current command, but also sets a limit to the duty cycle at the same % as the throttle.

does vesc support step/dir to control the motor?I want to build a CNC machine.thanks.

I've been working to implement OTA update for my custom hardware which has Arduino connected to UART. The Arduino has pre-loaded VESC firmware .bin image. I figured out most of the communication protocol and I can send commands to VESC and receive data back. The communication protocol has two packet types: below or above 256 bytes. The package type and length of the package is identified in the header of the packet and CRC is added to the end.

Hello All,

Like many others, I'm going down the path of converting a car alternator to give me a cheap but chunky BLDC to drive a kart.

Alternators are great for this: big solid frame, bearings and shaft, cooling fans. Just all-round heavy duty and built to last.

So far I did a quick proof of concept with a BMW/mini alternator rated to 110A and it was no problem at all, spinning up beautifully on a small RC ESC I had. With this quick success, I'm ready to move forward and build a heavy duty VESC to drive it hard and see what it can do.

what is the highest battery current the 6.6 firmware will allow? (per motor)

Hello everybody!  I faced a problem: when I use control type "Duty Cycle" and throttle (control type ADC) has full stop position, driver draw current nearly 0.1A (sometimes generate 0.1A). This current creates holding torque.

But I want to ride free-wheel on my bike. I saw the answer by Benjamin in this topic:

Hey there, 

i am running a custom application for an e-bike using Hall signals as well as an ADC input for a Potentiometer.

This is all working great but i want to use UART for a Bluetooth module together with the custom application.

Is there any possibility to start the UART application in the custom application?

Hello,

I am designing a small IPM motor and I need to select a controller for the motor. I am thinking of using VESC® 6 MKIII.

I have a few questions and just want to make sure if VESC is right for me and if it supports everything I need.

I tried to find the answers myself, but not sure if those answers are correct.

Anyhow, I would be grateful if someone can answer to following questions (or to confirm my assumptions):

1) Does the VESC support sensorless FOC with MTPA (maximum torque per ampere) control?
