I made a logical order to wire my components, starting with the most complicated and working down. In the case of my encoder, I had to make sure it was a certain distance and position from my board. I didn't add conductors for the keyswitches yet.
Wiring underside
I had some inspiration to write down my ideas for different screens. Each screen will represent a group of commands. For example, I could have a mouse emulating screen to control the cursor or a media control screen to play/pause, search, and change volume.
Proposed screens
I removed the analog code from my program, and I realized that was most of what I'd been focusing on. Between the infrared detection and pressure-sensitive finger rods, I lost a lot of time. When I tested my discrete keyswitches, I saw a lot of noise, but it calmed down when I held a pull-up resistor across the terminals. I'll update the circuit.
Pull-up resistors needed
I updated the circuit with pull-up resistors, but the problem didn't disappear. When I viewed the analog values, they looked steady, so I changed the code to recognize acceptable levels, then assigned arrow keys and moved a cursor around while wirelessly connected.
Changing cursor position
I wrote the encoder function that can differentiate between clockwise and counter-clockwise rotations. With previous microcontrollers, I had trouble because I wasn't using interrupt programming, but the ESP32 was fast enough that polling worked.
Screenshot of encoder testing
I gave on the encoder's pushbutton and removed the code until I can install physical pull-up resistors. I spent my time creating layers or sets. For example, one called "Arrow Keys" will type a different arrow when I press a button, and "Media control" can change volume and play or pause. These functions appear on the screen, and I can change them with the rotary encoder.
