Implementations

impl Pins

pub fn new(port: PORT) -> Self

Take ownership of the PAC [PORT] and split it into discrete [Pin]s.

This struct serves as a replacement for the HAL Pins struct. It is intended to provide more meaningful names for each [Pin] in a BSP. Any [Pin] not defined by the BSP is dropped.

PORT Pin Pins

pub unsafe fn port(&mut self) -> PORT

Take the PAC [PORT]

The [PORT] can only be taken once. Subsequent calls to this function will panic.

Safety

Direct access to the [PORT] could allow you to invalidate the compiler’s type-level tracking, so it is unsafe.
