Really appreciating the guide!
The example ‘Draw shapes on the Display – Code’ gives an error stating ‘OSError: transfer on deinitialized SPI’. This is because display.cleanup() is executed twice. The easiest way to prevent the error is to remove display.cleanup() above the try: statement.

Probably worthwhile to mention >
If you have a not fully filled 90deg rotated screen : change the rotation argument of the Display function in main.py from 90 to 0 (or 180).
If you have red and blue colors swapped : change the bgr argument of the class Display constructor (init) in ILI9341.py from True to False.

Great info again
How do you use the img2rgb565.py tool ?

Hi.
You just need to upload a new code using Arduino IDE.
If you’re using the Pico, you need to press the BOOTSEL button on the board at the same time that you connect the Pico to your computer so that it goes into bootloader mode. Everything is explained in this tutorial: https://randomnerdtutorials.com/programming-raspberry-pi-pico-w-arduino-ide/

Sara

But I would like you to cover how to uninstall MicroPython and go back to programming with the Arduino IDE. I have been unable to uninstall it from my raspberry pi pico.

Thanks for all you do.

$60 Micropython and LVGL open source ESP32 computer with touchscreen. See how they successfully integrated LVGL with micropython.

Bei der Konvertierung anderer Bilder in raw habe ich Probleme.
