Struct UarteRegistersManager 

pub struct UarteRegistersManager { /* private fields */ }

Wrapper for managing MMIO for UARTE.

Implementations

impl UarteRegistersManager

pub unsafe fn new_uarte0() -> UarteRegistersManager

Create a DMA-enabled register manager for UARTE.

Safety

This controls DMA hardware. As such, it must be unique. This requires:

• This constructor must be called at most once.
• There must not be any other code that accesses the DMA buffer and length registers.

pub fn start_tx_dma(&self, buf: SubSliceMut<'static, u8>) -> Result<(), ()>

Start a UART transmission with DMA.

Return

Ok(()) on successfully starting the DMA operation. Err(()) if the DMA is busy and the operation could not be started.

pub fn finish_tx_dma(&self) -> Option<(SubSliceMut<'static, u8>, usize)>

pub fn tx_dma_pending(&self) -> bool

pub fn start_rx_dma(&self, buf: SubSliceMut<'static, u8>) -> Result<(), ()>

Start a UART reception with DMA.

Return

Ok(()) on successfully starting the DMA operation. Err(()) if the DMA is busy and the operation could not be started.

pub fn finish_rx_dma(&self) -> Option<(SubSliceMut<'static, u8>, usize)>

pub fn rx_dma_pending(&self) -> bool
