UARTTivaDMA.h File Reference

Detailed Description

UART driver implementation for a Tiva UART controller thay uses DMA.

============================================================================

The UART header file should be included in an application as follows:

#include <ti/drivers/UART.h>
#include <ti/drivers/uart/UARTTivaDMA.h>

---

#include <stdint.h>
#include <stdbool.h>
#include <ti/drivers/UART.h>
#include <ti/sysbios/knl/Semaphore.h>
#include <ti/sysbios/family/arm/m3/Hwi.h>

Include dependency graph for UARTTivaDMA.h:

Typedef Documentation

typedef struct UARTTivaDMA_HWAttrs UARTTivaDMA_HWAttrs

UARTTivaDMA Hardware attributes.

These fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For TivaWare these definitions are found in:

• inc/hw_memmap.h
• inc/hw_ints.h

A sample structure is shown below:

const UARTTivaDMA_HWAttrs uartTivaHWAttrs[] = {
    {
        .baseAddr = UART1_BASE,
        .intNum = INT_UART1,
        .intPriority = (~0),
        .rxChannelIndex = UDMA_CH22_UART1RX,
        .txChannelIndex = UDMA_CH23_UART1TX,
    },
    {
        .baseAddr = UART3_BASE,
        .intNum = INT_UART3
        .intPriority = (~0),
        .rxChannelIndex = UDMA_CH16_UART3RX,
        .txChannelIndex = UDMA_CH17_UART3TX,
    },
};

typedef struct UARTTivaDMA_Object UARTTivaDMA_Object

UARTTivaDMA Object.

The application must not access any member variables of this structure!

typedef struct UARTTivaDMA_Object * UARTTivaDMA_Handle
