This project demonstrates how to bring up the JD9365-based MIPI DSI display and GSL3680 capacitive touch controller on the JC8012P4A1 board using Arduino.
- 10.1" JD9365 800x1280 MIPI DSI LCD display
- GSL3680 I2C capacitive touch support
- Backlight control via PWM (GPIO 23)
- Display updates using Arduino_GFX + ESP32-P4 DSI peripheral
- Touchpoint visualization (draws circle on touch)
- Basic Wi-Fi connectivity
- Board: JC8012P4A1 (ESP32-P4-based dev board)
- Display: JD9365 over 2-lane MIPI DSI
- Touch: GSL3680 over I2C
- Backlight: Controlled via PWM on GPIO 23
- Optional: Camera support (not yet configured)
| Function | GPIO |
|---|---|
| LCD Reset | 27 |
| Backlight | 23 |
| Touch SDA | 7 |
| Touch SCL | 8 |
| Touch RST | 22 |
| Touch INT | 21 |

- Add double buffering or frame sync to reduce tearing
- Integrate camera (if supported)
- Optional: Add LVGL support with input & widgets
