I purchased a Waveshare 3.5" TFT (LCD) display and cannot get it to work in the IDE 2.2.1 using C/pico I'm running Win 10 with 32Gb of memory. Despite the fact they say they have C demo code for it, they don't.
I have read the post back in 2021 but I'm pretty sure this is a new display even though it uses the ILI9488 driver.
I can get my pico to run simple programs (Blink, ASCII Table, etc.). Waveshare support on this product is useless as all they say is "See the demo" which I've been over a hundred times. I suppose one of the SPI pins could be bad, but I don't think so, plus I can see the backlight on the display.
If someone has any experience with the pico with C on any TFT display, I like to hear about it.
Yes, multiple times. I've followed the C instructions and I cannot get it to work. If you have a C version working, please send it to me. I'm starting to think I may have a bad display.
Well, I'm back on the Pico 3.5" Waveshare display issue and nothing's changed. However, your U2 clue made me pay more attention and I noticed this at the end of the compile:
Sketch uses 113596 bytes (5%) of program storage space. Maximum is 2093056 bytes.
Global variables use 11316 bytes (4%) of dynamic memory, leaving 250828 bytes for local variables. Maximum is 262144 bytes.

I don't have a Drive I. Clearly I"m not understanding something here. I'm trying to compile the example: UTFT_Demo_480x320.ino
