Hello, I have decided to learn how to use the pico by attempting to create an EINK typewriter. The project goals are outlined in GitHub here
In short, my idea is to use the following hardware:
- pi pico
- usb HID host in pico for keyboard input
- battery power on VBUS GPIO PIN
- EINK SPI screen
- Realtime clock to maintain time while powered off
The software would accept keyboard input from a usb keyboard and type it on the eink screen. Additionally, the typed characters would be written into a file in the onboard 2MB flash storage. Ultimately, i'd like to arrive at some kind of VIM type editor but that would come later.
Later on down the road, if things pan out, I'd like to add some form of wifi networking to send/receive documents and bluetooth keyboard support.
I'm looking for advise as to if my design is possible and/or any good!
