LPC55 HAL provides a high-level interface to the features of these LPC55 family of MCUs, which is safe, convenient and efficient. It leverages Rust's type system to prevent common mistakes, such as attempting to use an uninitialized peripheral; these will be caught by compile-time errors.
This library implements the
embedded-hal, a collection of traits intended to abstract
over platform-dependencies, allowing firmware and drivers to be quite portable.
It also implements the
Moreover, this library is compatible with the Cortex-M implementation of RTFM, a concurrency framework supporting preemptive multitasking with minimal footprint.
Very much work-in-progress!
Current peripherals that mostly work:
- I2C, SPI, Serial (with all pins)
- USB FS device
