Set up platformIO
To use all Flash and PSRAM from the ESP32-S3-devkitc-1 with 16MB flash and 8MB PSRAM, copy the file esp32-s3-devkitc-1-n16r8v.json (within the main folder) to C:\Users\<user>\.platformio\platforms\espressif32\boards\.
Otherwise use board = esp32-s3-devkitc-1, but in this case only 8MB flash and no PSRAM is used.
To use all Flash and PSRAM from the ESP32-S3-devkitc-1 with 16MB flash and 8MB PSRAM, copy the file esp32-s3-devkitc-1-n16r8v.json (within the main folder) to C:\Users\<user>\.platformio\platforms\espressif32\boards\. This is NOT done here as in this case the automatic build process on github fails. Instead the required board parameters for this board are defined within the device.ini file. Unfortenutel the define for using the complete 16MB causes a crash for some reason. So still 8MB flash are used. The FW still fits in this size.
additional branches
Two branches are included:
- support for Raspberry Pico 2: most instruments are not running due to less memory. Use instead a board with PSRAM, but this has to be tested in future
- rework of the StandbyAttitudeModule: for Airspeed and Altitude no additional sprites are used anymore. Check how it looks on the display! Some improvements could be also done for the AttitudeIndicator...
Flashing the ESP32
Download MobiDude and extract the content to e.g. your Desktop. Start MobiDude.exe, choose your your bin file, ESP32 as board, COM port, and press Upload
Caution! Your bin file must contain merged
Backlight Pin
As at least one Pin must be defined for a device and the pin for the backlight is not required for the TFT lib, this pin is now required to be defined in the Mobiflight Modules device dialog. Make sure this pin is properbly defined, it was Pin 13 for the ESP32 and Pin 0 for the Pico.
Known Bugs
- When deleting a display in the connector and defining a new one, the ESP32 crashes. This will give an error uploading fails. It's due to the TFT library. I haven't found a way to de-initialize the lib (it's simple not supported).
