2022-01-14 (F) Weekly Summary

I made hole templates on painter's tape and drilled the sides of the lunchbox to match. I should have just cut the large central hole and added the mounting holes afterward. I cut the first data port free, mounted it with three inches of wire off the back, and planned to use solder sleeves to reattach, but I decided to wait until I had a way to support the faceplate first.
MIDI ports drilled

I built a plate with bolts sticking up and placed it in the bottom of the lunchbox so my faceplate could rest on it. Next, I removed the MIDI connectors and installed them on the outside after reconnecting. I still have to check all my connections, but otherwise, I'm done building the first instrument panel.
Construction complete

I lucked out when it came to connecting my operators. I estimated a 12.5% chance of getting everything connected properly, and I happened to get it right the first time.
Screen and pot working against the odds

I figured out my problems with the button array. One issue was declaring pins correctly, and the other roadblock was recognizing rising edges, which was trickier than when each button had a unique input. I showed the button presses on the serial port.
Recognizing buttons

I ran into issues storing instrument names in the non-volatile memory. I did this because processor memory is precious, and I don't want to fill it with text. Even though I spent most of the day twisting it out, I didn't fix everything, but I constructed a preliminary screen that shows all the instrument choices.
The words I want

The code that reports instrument names broke the display again. I was trying to pull variables from an array I created to divide notes into beats neatly. I struggled with the messy code and settled on a workaround that displayed sentences like "1 note every 2 beats."
Play rate from a switch() statement
