Hi Trampas, It was great to see you subscribed to the list. Welcome!
First, thank you for the donations of gear for Saturday's fundraiser. Together with the stuff I donated Nick and I raised $672 for two NC First Robotics teams (PyroTech and TerrorBytes) going to the world championship this week in Houston.
If you want a couple of the Seeed display boards to experiment with I can arrange that.

Arduino is great to get something working quickly but Arduino libraries in my experience are full of bugs, err 'features'. Hence If you want to create something stable it is best to use arduino code and libraries as educational examples. If there is an interest in this LCD I will order one and make up a sample project and tutorial. I even have some spare Cortex M0+ boards (ATSAMD21) I can provide to those interested, so everyone is using the same processor.

Their ILI9341 driver (and/or how their GFX library works with it) has changed over the years and in some subtle and this has caused it to stop being compatible. So the first URL is useful but the second is problematic. -Pete On 4/18/22 14:58, Trampas Stern wrote: I think this is the Seeed one: https://wiki.seeedstudio.com/2.8inch_TFT_Touch_Shield_v2.0/ It appears to use the *ILI9341 *driver chip. The ILI9341 chip is what you are talking to via the SPI interface to turn pixels on and off. Adafruit has some examples and tutorials on how to use the ILI9341, note the adafruit lcd/board is different, but process should be similar: https://learn.adafruit.com/adafruit-2-8-and-3-2-color-tft-touchscreen-breakout-v2/spi-wiring-and-test Here is the ILI9341 datasheet: https://cdn-shop.adafruit.com/datasheets/ILI9341.pdf I have used the ILI9341 (as well as several other LCD controllers) on past projects, so if anyone needs some help I will be happy to help. If there is enough interest I would not mind setting up an online(zoom) tutorial session. In general if anyone needs help solving hardware or firmware problems, please let me know and I will do my best to help.

Could you point us to the web page(s) you found the firmware resources on? I've poked around the Seeed github site and don't see this. Or is it in their wiki?
