I’m looking at what is the best way to connect the A-Star 32U4 Micro to the new 2.2" 18-bit color TFT LCD display from Adafruit. The pinout for the A-star has fewer pins than the normal Arduino.
That TFT LCD display from Adafruit uses SPI to communicate. You should be able to use the SPI pins on the ISP header on the A-Star to communicate with that display. You might find the diagram below helpful for using those pins (we will try to add this to the user’s guide soon).
The numbers on those three pins correspond with the Arduino pin numbers.
Thanks will try this out
