Hey I have the 12 pin ST7789 display but instead of using the 7 pin module display I am trying to connect the bare 12 pin display itself. I used this library to upload the Hello World sketch to my Arduino and it works fine on the 7 pin module version of the display. However when I wire up the 12 pin the screen flashes white before going blank.
Here are my connections:
All 4 GND of display: GND on Arduino,
LEDK: 3.3V Power,
LEDA Arduino GND,
VDD: 3.3V,
D/C: D7 on Arduino,
CS: GND,
RES: D8 on Arduino,
SDA: SDA on Arduino,
SCL: SCL on Arduino.
Since this works with the module version I assume it's a wiring issue. Anyone else here able to use the bare 12 pin screen with Arduino? Appreciate any help I can get, thanks.
