Unfortunately, the Adafruit library doesn't play well with this
display. 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.

I think this is the Seeed one:

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.
Thanks

It was the Wiki and was V2.0- brain fart on something else I was

All worked well for me even with the very latest Arduino iDE (.19)

The displays from the hamfest are V2.0 but I'm excited this more
recent stuff is compatible. 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?
