Crate apu_pcengines_hal

A safe wrapper around the direct memory interface of the APU2+ hardware.

This is a typesafe zero-cost abstraction over raw pointers. To adhere to rusts safety there are runtime checks and all pins must be returned with Mapping::free_pin

use apu_pcengines_hal::{MappingResult, APU_LED1, APU_LED2, APU_LED3};

fn main() -> MappingResult<()> {
    let mut map = apu_pcengines_hal::init()?;

    println!("init done: {:?}", map);

    let led2 = map.get_pin(APU_LED2)?;
    println!("led2: {:?}", led2);
     
    let mut led2 = led2.into_input();
    let val = led2.get();
    println!("led2: {:?} = {}", led2, val);
     
    let mut led2 = led2.into_output();
    println!("led2: {:?}", led2);
    led2.set(!val);
     
    map.free_pin(led2);
    Ok(())
}
