Experimental · All profiles compile · Physical display testing is still needed.

Edit the code in Arduino IDE+

One .ino file for the selected board and display, with all project code inside. The flash button above needs no setup; use this when you want to change the code.

↓ Download .ino
  1. Install the ESP32 core: in File → Preferences, add this Additional boards manager URL, then install this version in Boards Manager.
  2. Install these libraries in Library Manager:
    • Choose these in the Tools menu:
    • Open the .ino (Arduino IDE offers to create its sketch folder), click Upload, then open Serial Monitor at 115200.

    If the upload says "No serial data received": hold BOOT, press and release RST, release BOOT, then upload again. Upload Speed 115200 can also help.

    No port, or a blank display?+
    Try a USB data cable, close Serial Monitor, and hold BOOT while plugging in USB. Release BOOT and try flashing again.
    Modules may need different inversion or SPI settings; change them from the device web page. An offset ST7735 image or an SH1106 OLED needs an adjusted profile and a new build.
    The installer offers installation and erase options. Erasing flash deletes saved settings.
