[KurtE]

One other thing... When you say flicker, is the display actually working, but not working well, and only readable when reset?

Maybe it is because the SPI transfer code to update the screen, is not fast... Read that as

Wonder if I should make a version of our Teensy version of the ST7789 library like I did for the ILI9341 as discussed in the thread:

Adafruit_ILI9341 and SPI library issues on GIGA board

Note: This is related to the thread: However, thought maybe better to not diverge that thread, to discuss issues with SPI and the Adafruit library. As mentioned in the other thread, I am able to get their graphics test example to run on the GIGA, using the bitbang version of SPI. That is using the constructor: #define TFT_DC 9 #define TFT_RST 8 #define TFT_CS 10 #define TFT_MOSI 11 #define TFT_MISO 12 #define TFT_CLK 13 Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_MOSI, TFT_C…

Edit: Oops, don't remember if I made it work for UNO R4... Did for GIGA and Portenta
