<br>
<p> It was great to see you subscribed to the list. Welcome!<br>
</p>
<p><span dir="ltr" style="margin-top:0; margin-bottom:0;"> 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.</span> </p>
<p> <span dir="ltr" style="margin-top:0; margin-bottom:0;"> If
you want a couple of the Seeed display boards to experiment with
I can arrange that.<br>
</span></p>

sums up Arduino and Arduino libraries in general! </span> <br>
<br>
<span dir="ltr" style="margin-top:0; margin-bottom:0;">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. </span> <br>
<br>
<span dir="ltr" style="margin-top:0; margin-bottom:0;">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. </span> <br>

<span dir="ltr" style="margin-top:0; margin-bottom:0;">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.</span> <br>

<br>
<span dir="ltr" style="margin-top:0; margin-bottom:0;">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:</span>

<br>

<br>
<br>
<span dir="ltr" style="margin-top:0; margin-bottom:0;">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. </span> <br>
<br>

general if anyone needs help solving hardware or firmware
problems, please let me know and I will do my best to help. </span>

<br>
<span dir="ltr" style="margin-top:0; margin-bottom:0;">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?</span> <br>
