Absolutely brilliant video and a wealth of knowledge. Thanks so much for sharing. All works as posted :)

13:18 you have forgotten to refresh the code when ever the red pointer moves. It rubs out degrees.

Do you have a recommendation for a program or app that will convert jpg or bmp image files into arrays for use with microcontrollers and TFT displays? All the best ...

Welcome return to a great channel...
Hope you are well?

Any chance sometime you could do a micropython/ circuit python version of this guide please?

11 MONTHS since last video on this channel :(

It would be great to do a project that takes an analogue input from a sensor or potentiometer and displays a scaled value on a gauge display.

Great video!! Hope to use this round display and Pico to make operating clock faces for my HO scale railroad. Can I simultaneously run more than one display using the Pico SPI signals? I'll need either two or four clock faces for my building tower. All the best to you ...

Im having trouble getting the display to work, could you share any information about what firmware is needed for the Pico ? Do you need precompiled firmware with the driver already installed, or can the driver be installed manually with the micropython firmware ? Any help would be appreciated! Great Video otherwise.

hi. my lcd screen has 20 pin. how do I connect it to arduino ? The seller provided information on each pins but that's everything

Have the Arduino people fixed the IDE so that it can use COM ports? My Pico disconnects at the outset of the upload with this error: "Cannot Perform port reset: 1200-bps touch: opening port at 1200bps: Invalid serial port"

you should write ‘round’ in the headline instead of ‘roud’ ;)
