Hi,
I've been struggling today with a Teesy-4 and a ST7789 240x240 1.3 Inch display without a CS pin.
Whatever library I try, I don't get an image, only a vague gray background.
I use the standard SPI0 pins 11(SDA) and 13(SCL) and pin 8(RES) and 9(DC) and of course the power pins.
Can somebody explain to me which library to use and give me some sample code without code for any other display in it or al kind of test in it.
All I need is the setup for this display and an *.ino file with Hello World example.
None of the libraries I found have such an example...
used this library: ST7735_t3-master
used this library: Arduino_ST7789_Fast-master
And this library: Adafruit_ST7735_and_ST7789_Library
I am grateful for all the help,
Bram
