This repository hosts the code for an Arduino-based project that enables you to view statistics from your VESC (Vedder Electronic Speed Controller) on an I2C LCD screen. The project is designed for electric bikes (E-bikes) and is inspired by Tom Stanton's VESC E-bike.
The code allows you to monitor various stats about your E-bike in real-time, including speed, power, current, temperature, and more. It's a great tool for E-bike enthusiasts who want to keep track of their bike's performance and health.
The project uses a VESC 6 to control the E-bike and an I2C 4x20 LCD screen to display the stats. It also includes an optional Python-based LCD emulator for testing the LCD display functions without needing an actual Arduino or LCD screen.
The project requires the following components:
Optional components include (adjustments to Ebike.ino may be required):
- DS3231 I2C Real Time Clock
- Buck Boost Converter
- 10k at 25°C NTC Thermistor (Adjust B value in
Ebike.inoto your sensor!)
This is the circuit schematic I am using, feel free to use it and modify the way it works!
The main Arduino sketch for the project is Ebike.ino. This sketch controls the behavior of the E-Bike, including reading data from the VESC and displaying it on the LCD screen.
The lcdem directory contains a Python-based LCD emulator. This emulator can be used to test the LCD display functions without needing an actual Arduino or LCD screen. The main scripts for the emulator are Ebike_good.py and lcd.py.
Ebike_good.py is a script that simulates the data that would be sent from the Arduino to the LCD screen. It sends data to lcd.py, which emulates the LCD screen and displays the data.
If you encounter any bugs, please feel free to open an issue or make a pull request. Thanks!
