2023-02-20 (M) EWC_Box Functioning screen

I played around with different settings to find what I could break and what I needed to keep intact. I connected the "RESET" pin to voltage, and it functioned yesterday, so today, I joined it to an IO point and turned it on, but it failed. The screen worked if I pulled that pin high and waited ten milliseconds before sending a command. "CS" and "DC" worked with any IO point, so I gathered the screen has a finicky startup routine. I took this knowledge to the EWC_Box enclosure and ran the same demo sketch with the updated pins and delays, but I saw something when I pressed the Arduino's reset button. I tried a few things, and it worked well after I removed power to reboot the system. The startup routine is as touchy as I feared. More importantly, the screen works.

I added a feature to my encoder testing program that sent a signal to Serial2, my MIDI port, whenever I turned a knob. I tested the faceplate's MIDI port with a homemade module. The voltage and signal wires were reversed because a red light activated. I desoldered the wires and put them into the correct order. The tester showed a green light this time, so my port works, but this does not indicate if my synthesizer works.
