apu_pcengines_hal
A safe wrapper around the direct memory interface of the APU2+ hardware.
Installation
With cargo (or rustup) from git
sudo apt install build-essential
git clone https://gitlab.com/dns2utf8/apu_pcengines_hal.git
cargo build --release --example leds
sudo ./target/release/examples/leds
Download nightly from gitlab:
The CI builds the binary on the main
branch on every commit.
You can download the leds example program from https://dns2utf8.gitlab.io/apu_pcengines_hal/leds or use these commands:
wget https://dns2utf8.gitlab.io/apu_pcengines_hal/leds
sudo ./leds
lib.rs
:
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(())
}
