This is the default core used in the Domino4 eco-system.
The core is built around the ESP32-WROOM-32 module from Espressif. Future versions of this core will be using newer version of the ESP32 chipset.
- To program the Domino4 cores using Arduino, install the board files using the doumentation from Espressif
- Please read the notes regarding upload/transfer speed when using the PPU.
- Settings:
- Board: Choose the
ESP32 Dev Module - Speed: Max 460800 bps
- Port: Chose the port where your PPU is inserted. If you cannot see the port, the check out your PPU installation
- Board: Choose the
- Download the MicroPython firmware from micropython.org
- It is recommended to download and use the (Mu Editor)(https://codewith.mu/en/download)
- You can use the Mu Editor to upload the MicroPython Firmware.
