Macro Definition Documentation

PLATFORM_UART_EVENT_TX_DONE

#define PLATFORM_UART_EVENT_TX_DONE   (1U << 0)

Configure the UART core for 115200 baud 8-N-1, no HW flow control.

Note

Make sure that data being passed to otPlatUartSend is in persistent readable memory. Event identifiers passed back to the stack task callback.

Referenced by platformUartProcess(), and uartWriteCallback().

PLATFORM_UART_EVENT_RX_DONE

#define PLATFORM_UART_EVENT_RX_DONE   (1U << 1)

Referenced by platformUartProcess(), and uartReadCallback().

PLATFORM_UART_RECV_BUF_LEN

#define PLATFORM_UART_RECV_BUF_LEN   32

Size of the statically allocated buffer to pass data from the callback to the processing loop.

uartReadCallback()

static void uartReadCallback ( UART_Handle  aHandle, void *  aBuf, size_t  aLen  )

static

Callback for when the UART driver finishes reading.

This is triggered when the buffer is full, or when the UART hardware times out.

uartWriteCallback()

static void uartWriteCallback ( UART_Handle  aHandle, void *  aBuf, size_t  aLen  )
