DMA peripheral hardware-handshaking request ID.

Values are the HAL_DMA_HANDSHAKING_* indices from fbb_ws63 drivers/chips/ws63/porting/dma/dma_porting.h — the hardware request line a channel uses for peripheral-paced flow control. They go into the channel config’s src_peripheral / dst_peripheral field (a 4-bit field; all the IDs below fit). UART bus mapping per platform_core.h: UART0 = UART_L, UART1 = UART_H0, UART2 = UART_H1.

(These superseded the earlier fabricated sequential 0..11 values; only the main-DMA (MDMA) sources ws63-hal models are listed — the SDMA-group I2C IDs (≥29) don’t fit the 4-bit field and aren’t modelled here.)

Variants

Tie0 = 0

No handshaking (tie-off) — used for memory-to-memory transfers.

Uart0Tx = 1

UART0 (UART_L) transmit.

Uart0Rx = 2

UART0 (UART_L) receive.

Uart1Tx = 3

UART1 (UART_H0) transmit.

Uart1Rx = 4

UART1 (UART_H0) receive.

Uart2Tx = 5

UART2 (UART_H1) transmit.

Uart2Rx = 6

UART2 (UART_H1) receive.

Spi0Tx = 7

SPI0 (SPI_MS0) transmit.

Spi0Rx = 8

SPI0 (SPI_MS0) receive.

I2sTx = 11

I2S transmit.

I2sRx = 12

I2S receive.

Spi1Tx = 13

SPI1 (SPI_MS1) transmit.

Spi1Rx = 14

SPI1 (SPI_MS1) receive.

Implementations

impl DmaPeripheral

pub const fn request_id(self) -> u8

The hardware handshaking request ID (the dma_porting.h index), as programmed into the channel config’s peripheral-select field.

Trait Implementations

impl Clone for DmaPeripheral

fn clone(&self) -> DmaPeripheral

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DmaPeripheral

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DmaPeripheral

fn eq(&self, other: &DmaPeripheral) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
