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.

   I think that pretty much sums up Arduino and Arduino libraries in
   general!

   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.

       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:
           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.

           Thanks
           Trampas

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



               https://wiki.seeedstudio.com/2.8inch_TFT_Touch_Shield_v2.0/





               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?

               Pete
