eepyOS (WIP)#

eepyOS is a barebones, application-specific, single-tasking operating system in Rust for my Touchscreen E-Paper Input Module for the Framework 16, designed to allow safe execution of user programs. Currently a major work in progress.

Summary of crates:

  • eepy - eepyOS kernel
  • eepy-sys - library defining the kernel's syscall interface and binary format and providing safe abstractions
  • eepy-derive - proc macro crate for eepy-sys (the name is a misnomer as it doesn't actually contain any derive macros, but it's too late to change now)
  • eepy-launcher - the userspace component of eepyOS which handles the launcher UI
  • eepy-gui - barebones UI library for eepyOS applications based on embedded-graphics
  • eepy-example-app - example userspace application for eepyOS
  • eepy-serial - library crate for the USB serial interface
  • eepytool - CLI tool for interfacing with the input module over USB serial
  • elf2epb - utility for converting ELF binaries to eepyOS's binary format
  • fw16-epd-bsp - Board Support Package for the Touchscreen E-Paper Input Module
  • pervasive-spi - Bitbanging driver for the 3-wire SPI protocol used by Pervasive Displays e-paper panels, such as the one on the Input Module
  • tp370pgh01 - Driver for the specific display used on the Touchscreen E-Paper Input Module (display only; touch is handled directly in the kernel)
