<p>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.<br>

<div>It appears to use the <b>ILI9341 </b>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:</div>

<div><br>
</div>
<div>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. </div>

<p>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?</p>
