My question is:
Is there a difference between the NANO and MEGA that would account for ST7735 displays working on NANO and not working on MEGA? I'm using the same pins on both....
Pin 8 is RS (RS/DC)
Pin 9 is RST (RES)
Pin 10 is CS
Pin 11 is SDA
Pin 13 is CLK (SCL)
The displays have slightly different labels for the pins (hence the labels in parenthesis).
I'm relatively new to Arduino and just bought two 1.8in TFT LCDs from different manufacturers.
I am having problems getting them to work on my Arduino MEGA 2560.
After experiencing failure with the MEGA using both displays and 2 different sketches, I finally decided to try the displays and sketches on a Nano.
Both displays work with both sketches on the NANO but not with the MEGA.
I'm using Adafruit_GFX and Adafruit_ST7735 libraries.
Im guessing there is a difference between MEGA and NANO that I am overlooking or that my MEGA has some problem....
Thanks in advance.
