VESC Tool helper for VESC based onewheels

Version 0.1.12 - 2024-10-14

This tool will help you find the key values to configure your board in VESC Tool, depending on your controller, batteries, tire and motor. To get started, select the components used in your board.

Controllers

Batterypacks

Batteries

Tires

Motors

VESC Tool Config

Next, run Motor Detection, calibrate the IMU, install the Refloat package (or Float Package if you care more about haptic buzz than LEDs), and configure your board using the following menus and values in VESC Tool.

If you are wondering what all these parameters are for, check my parameter tool, which aggregates all help texts from VESC Tool and some common packages.

Scan…	Scan BLE until you can connect to your controller (top right button)	CONNECT
CAN scan	Your controller connects through a VESC Express module, so now you have to scan the CAN bus to connect to your actual VESC (on mobile, the button is on the bottom right)	Scan CAN Bus

Finally, you can play with the LED setup in Refloat, install Floaty or Float Control, and apply your favorite tunings for ATR etc.

Corrections and additions

This is work in progress. Getting all the info to make this tool function is quite a lot of work. If you look at the compare tables, you'll still see quite a lot of gaps. If you know details that I don't have in my tables yet, be it individual parameter values, corrections, or complete components, please download one of the component files below, edit it, and mail it back to me. Please indicate the fields you corrected with a light red background color, and stuff you added with a light green background color - that would save me a lot of time. Thanks if advance for your help!

Open Source

The VESC Tool Config Helper is an open source project, published under the MIT license, with some minor additions. It is meant to benefit the Onewheel Vesc Builders for free, and I invite everyone to contribute, either in our Facebook group, or per e-mail (see above), or soon also on github. I already set up the project on github, where I will upload most files asap. Exceptions are the PHP file that generates the HTML for this page, and the project database that generates most of the JSON used here. The contents of that database are not secret, (add ?pretty=1 to the url to get better readable json code), but at the moment, I'd like to keep control of those 2 files. As soon as the software is a bit more stable, I'll probably add that to the repository as well.

Warning

If you look at the compare tables, you'll see that we still have many data gaps. I don't want to guess values, so for those gaps, we mostly use the defaults from VESC Tool. VESC Tool however is not specifically made for balance boards, so those defaults may not always make sense in our community. For some parameters, I overrule the VESC Tool defaults with our own. But the only thing that really helps is if we have complete information directly from the manufacturers. If you have connections to them, please send them to this page, and let them fill in the Excel sheets for their products (see above).

PS. Most battery info comes from NKON for consistency. NKON is also the place where I personally buy my batteries. Huge choice, good prices. I'm not affiliated to them in any way.
