I am learning to use your METRO 328 and 2.0" 320x240 Color IPS TFT Display with microSD Card Breakout. I have successfully compiled your suggested Adafruit_ImageReader test for Adafruit ST7789 320x240 TFT Breakout for Arduino. Thank you for providing all of the initial training documentation.
I am compiling with Tools/Board: "Arduino Uno". I see that Sketch uses 29204 bytes (90%) of program storage space. That does not leave me much room for my future code.
Is there a Metro Board library that I need to install?
Thank you very much for your help.

Re: Metro and 320X240 Color Display
Good job getting things going so far.
The Metro 328 is Arduino UNO compatible so you do not need to install a board specific library.
There are newer models of the Metro that are M0 and M4 based. They have a great deal more memory and would be the way to go if you plan on driving a LCD display.

https://www.adafruit.com/product/2488The METRO works great with the Arduino IDE, and runs the ATmega328P at 16MHz so it is shape and pin-compatible with Arduino UNO R3 shields and boards. You can use this with the Arduino IDE (both desktop and cloud version) by selecting 'Arduino UNO' in the Boards menu.
