Rust on microcontrollers

• Minimal blinky
  • Barebones blinky example i.e linker script to main
• Minimal buildsystem
  • Initial cargo-make framework to have configurable build options i.e extending cargo
• Minimal controller peripheral
  • Use bindgen to transform .c architecture and chip files to .rs
  • Create l0 and l5 workspace layers
  • Add architecture, controller and startup files in l0
• Minimal Drivers
  • Write GPIO and USART drivers for high level application usage
  • Added l2, l3 and l4 workspace layers
  • Added bitflags utility library in l2 via crates.io
  • Added driver interfaces, gpio, usart drivers in l3
  • Added led and button modules in l4
• Minimal Interrupt
  • Configure interrupts from high level application code
  • Updated l0 l2, l3 and l4 workspace layers
  • Updated l0 with user interrupt considerations
  • Added heapless library to l2
  • Added USART buffered traits to l3

• Minimal Async Basic
  • Forked from Minimal Interrupt
  • Configure Interrupts and main loop with rust cooperative async/await
  • No executor/waker implementation. Just basic polling functionality

• ARM Cortex M4

TODO, Add more eventually

• STM32L475xx
• LPC4078xx
