1bitsy Board Support Crate

This crate is relatively untested

It wraps up and makes more obvious how to use:

• the set of Pins supported by the board
• the onboard LED on PA8
• the onboard button on PC1
• the onboard 25MHz high-speed oscillator crystal

Board support crate for the 1Bitsy

Usage

use onebitsy::{self, stm32, Led, Button};
use cortex_m_rt::{entry, exception};

#![entry]
fn main() -> ! {
  if let (Some(dp), Some(_cp)) = (
      stm32::Peripherals::take(),
      cortex_m::peripheral::Peripherals::take(),
  ) {
      let _clocks = onebitsy::configure_clocks(dp.RCC.constrain());

      let pins = onebitsy::Pins::new(
          dp.GPIOA.split(),
          dp.GPIOB.split(),
          dp.GPIOC.split(),
          dp.GPIOD.split(),
      );
      let mut led = onebitsy::led(pins.pa8);
      let button = onebitsy::button(pins.pc1);

      loop {
          if button.is_pressed() {
              led.on();
          } else {
              led.off();
          }
      }
  }

  loop {}
}
