Crate mmreg 

mmio Library API

This crate provides safe, concurrent access to 32-bit memory-mapped IO registers via /dev/mem. It is designed for use in CLI tools, controllers, and logging utilities that need direct register access.

Example Usage

use mmreg::{read_register_at, write_register_at};

// Read a 32-bit value from a physical address
let value = read_register_at(0x4000_0000)?;

// Write a 32-bit value to a physical address
write_register_at(0x4000_0000, 0xDEADBEEF)?;
