CYD Deskpad (xtTouch/ESP32/CheapYellowDisplay)

I loved the original model, but I had to make a few tweaks! This version is specifically modified for the xTouch/ESP32-2432S028, also known as the Cheap Yellow Display.

Features:

• Cherry MX Switches: Equipped with holes for 4 Cherry MX switches, providing a satisfying tactile input experience.
• Sturdy Build: Uses 4x 12mm M3 screws to secure the faceplate to the base, keeping everything tight and stable.
• Expandable Interior: Plenty of space inside for additional components like a battery and speaker—perfect for expanding your setup.

Note: Limited Display I/O Solution

The display's I/O is limited, but you can still connect the 4 buttons easily by following these steps:

1. Tie one lead of each button to ground.
2. Connect the other lead of each button with different resistors (1kΩ, 5kΩ, 10kΩ, and 15kΩ respectively).
3. Combine all outputs and connect to IO pin 21 as an input.
4. Use analogRead() on pin 21 to get values between 0 and 4098, allowing you to effectively differentiate between button presses.
