USB-HID dongle for SlimeVR tracker over ESP-NOW. Runs on M5AtomS3.

SlimeVR USB-HID dongle for trackers over ESP-NOW

This is a USB-HID dongle code for M5AtomS3. The sensor data is received over ESP-NOW.

SlimeVR server v0.12.0 rc.1 introduced USB-HID sensor support. This code uses this feature.

Not tested well.

USB接続の無線ドングルのコードです。M5AtomS3で動きます。センサーからはESP-NOWでデータを受信します。

SlimeVR server v0.12.0 rc.1 ではUSB-HIDのサポートが追加されていて、それを利用しています。

十分にはテストされていません。

  • Use my fork. One direction transmission (sensor to dongle; no pairing)
  • https://github.com/verylowfreq/SlimeVR-Tracker-ESP-ESPNOW
• M5AtomS3 (ESP32-S3)
  • Should be work with generic ESP32-S3 board (except NeoPixel on GPIO 35)
• Arduino IDE / Board: arduino-esp32
  • NOT the board library provide from M5Stack

How to build / ビルド方法

1. Open the .ino file.
2. Tool -> USB Mode: USB-OTG, Upload Mode: USB-OTG
3. Verify
4. Upload
5. Reset M5AtomS3 manually

Known issues / 既知の問題
