Example project for ODROID-GO using ESP-IDF on PlatformIO
- LCD driver from ESP32 IoT Solution based on Adafruit’s Library for ILI9341
- GPIO buttons support through button component
- D-pad (ADC) support
- Sound driver (speaker)
The D-pad is connected to IO34/35 and uses analog multiplexing. It might be possible to poll the ADC from the ULP to generate interrupts.
