This crate provide as simple to use and safe abstraction of the GPIO's available on the Raspberry Pi 3. The GPIO configuration requires access to MMIO registers with a specific memory base address. As this might differ between different models the right address is choosen based on the given ruspiro_pi3 feature while compiling.
To use the crate just add the following dependency to your Cargo.toml file:
toml
[dependencies]
ruspiro-gpio = "0.4"
Once done the access to the GPIO abstraction is available in your rust files like so:
```rust use ruspiro_gpio::GPIO;
fn demo() { // "grab" the GPIO in a safe way and use the provided closure to work with it // as long as the closure is executed, no other core can access the GPIO to configure pins etc. GPIO.takefor(|gpio| { // retrieving a pin gives a Result<>. If the pin is not already taken it returns an Ok() // with the pin. if let Ok(pin) = gpio.getpin(17) { // as we have now access to the pin, configure it as output and set it to high // to lit a connected LED pin.to_output().high(); } }) } ```
