ral-registers

This crate contains an MMIO abstraction that uses macros to read, modify, and write fields in registers.

For example, several fields on a register can be updated (without changing the other fields) using:

// Modify some fields on GPIOA.MODER without changing others.
modify_reg!(gpio, GPIOA, MODER, MODER1: Input, MODER2: Output, MODER3: Input);

// Check a condition on a field.
while read_reg!(gpio, GPIOA, IDR, IDR3 == High) {}

// Read and write the entire register word value.
let port = read_reg!(gpio, GPIOA, IDR);
write_reg!(gpio, GPIOA, port);

This crate contains register code originally written in stm32ral, extracted for easier use in other projects.
