2023-02-25 (Sa) EWC_Box More screen problems

I wanted to start creating visuals for the device, but my screens stopped working. I made all the necessary changes and followed all my findings, but I could not get the one in my enclosure or my spare hardware to work. This was getting old. I tried the same steps to isolate the problem by manually triggering pins and physically connecting terminals, but nothing worked. I deleted and reinstalled the drivers, but the best I could manage was a faint screen image and a clear view if I held the reset button.

The problem may have come from the 5V signals on several pins, while the rest of the module used 3.3V. When I connected the main power to 5V, I saw vibrant colors, but the picture was jittery, so I would wager overvoltage harms the chip. I soldered pins to a four-channel level shifter and added it to the system. I fed two inputs from an Arduino, but they worked best when I tied them to Vcc or GND. I did all the experimenting on a small solderless breadboard.
