Crate bl702_hal

HAL for the BL702 microcontroller

This is a Rust HAL for the BL702 microcontroller.

It implements the embedded-hal traits for peripherals, where such traits exist.

Usage

Commonly used setup

// Get access to the device specific peripherals from the peripheral access crate
let dp = pac::Peripherals::take().unwrap();
let mut parts = dp.GLB.split();

To avoid the linker to complain about missing symbols please add hal_defaults.x to .cargo/config like this

rustflags = [
  "-C", "link-arg=-Tmemory.x",
  "-C", "link-arg=-Tlink.x",
  "-C", "link-arg=-Thal_defaults.x",
]
