You need a HID gamepad device to test the project. I put my test code for the MCU(ESP32) in the package already. If you use your own MCU, you should config the right HID input and output report.

For this example, I can control the motor's speed and the color of LED ring, and the device will upload the motor's speed and TH sensor data.

This package had been tested on Unity 2019/2020
