Rust library for accessing the physical address space using /dev/mem similar to busybox devmem

Installation

Add ddevmem to your Cargo.toml:

[dependencies]
ddevmem = "0.2.2"

Example

use ddevmem::{register_map, DevMem};

register_map! {
    pub unsafe map MyRegisterMap {
        0x00 => rw reg0: u32,
        0x04 => ro reg1: u32,
        0x08 => wo reg2: u32
    }
}

let devmem = unsafe { DevMem::new(0xD0DE_0000, None).unwrap() };
let mut reg_map = unsafe { MyRegisterMap::new(std::sync::Arc::new(devmem)).unwrap() };
let (reg0_offset, reg0_address) = (reg_map.reg0_address(), reg_map.reg0_offset());
let reg1_value = *reg_map.reg1();
*reg_map.mut_reg2() = reg1_value;
