Display Keyboard

This project is the hardware design and software for a USB keyboard with an integrated touch display.

Hardware features:

• Mechanical keys.
• FeatherS2. This is a ESP32-S2 based embedded development board.
• 2.8" LCD capacitive touch display.
• 0.91" vertical OLED display for volume display.
• Volume control knob.

The FeatherS2 conforms to the Adafruit Feather requirements, and allows for the possibility of replacing that MCU with another Feather with little (if any) PCB rework.

Hardware Design

Design is done in KiCad. Files are located in the pcb directory.

Software Requirements

• ESP-IDF
• VS Code extensions (optional)

Getting Code

git clone https://github.com/jack-mumford/display-keyboard.git
cd display-keyboard
./make submodules

Note: This project makes use of new features (USB) of the ESP32-S2 and requires ESP-IDF v4.3.

Building

Do this after opening a new terminal window:

. $HOME/esp/esp-idf/export.sh

Build and flash to the attached ESP32-S2 device as so:

./make flash

Configuration (GPIO pins, etc.) is stored in the sdkconfig.defaults file. This can be changed using menuconfig as so:

./make config
