usb-display-device

Programms to use adafruit display as usb display with linux

BUILD

nix build .#componentName

COMPONENTS

display

rp2040 firmware to drive adafruit sharp memory display over spi displaying static frame as first prototype

###usb_echo rp2040 firmware to echo back data received over usb from host computer used as second prototype to test usb data transfer

###usb_echo_driver linux driver counterpart to work with usb_echo sends hard coded data packet over usb on data received logs it to dmesg

usb_display (not sure on data transmission protocol)

rp2040 firmware to drive adafruit sharp memory display over spi displaying frame sent over usb from host computer

usb_display_driver (not implemented yet)

linux driver counterpart to work with usb_display sets up relevant components for linux drm subsystem to work with wayland etc. reads out framebuffer and sends data over usb to display (rp2040)

TODO

• go over first prototypes again
• define protocol to send framebuffer or adafruit sharp memory display commands
• implement basic driver using hard coded framebuffer data
• read into drm subsystem to implement components for framebuffer driver
