Pinpointing ST7735R LCD Errors with White Color Full Screen

Hi guys,

White color full screen has been an incredibly helpful analyzing issues with my ST7735R LCD screen during my Arduino project. By using whitescreen, I was able to confirm that the display hardware is functioning correctly and pinpoint when the screen goes completely blank and blinking during operation.

I’m a bit new to engineering, electronics, and Arduino, so here’s a breakdown of my project. I’m modifying an old nerf gun to be powered by a pneumatic piston. The piston primes the gun and shoots darts farther. Additionally, I have added an IR camera and a regular camera, and I’m currently figuring out how to interpolate the IR camera data.

I’m using a standard Arduino Uno for this project, nothing off brand. When I run basic example code for the 8x8 display mode, everything works fine. However, when I attempt to use the interpolation example code, my ST7735R LCD screen goes completely unresponsive.

I have already checked all connections, and everything seems to be in the correct place. However, I’m not experienced enough with coding to figure out if there is an issue with the example code itself or something else I’m missing.

Has anyone faced a similar issue with the ST7735R LCD screen, or can anyone suggest ways to resolve this? any suggestions?
