mcuxpresso ide串口发送10byte数据

以下是在MCUXpresso IDE中使用串口发送10字节数据的示例代码：

#include "board.h"
#include "fsl_debug_console.h"
#include "fsl_lpuart.h"

#define EXAMPLE_LPUART_BASE (USART0_BASE)
#define EXAMPLE_LPUART_IRQ (USART0_IRQn)
#define EXAMPLE_LPUART_IRQHandler (USART0_IRQHandler)

#define EXAMPLE_LPUART_TX_BUFFER_LENGTH (10)

uint8_t lpuartTxBuffer[EXAMPLE_LPUART_TX_BUFFER_LENGTH] = {0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A};

volatile bool txBufferEmpty = true;

void EXAMPLE_LPUART_IRQHandler(void)
{
    /* If new data arrived. */
    if ((kLPUART_RxDataRegFullFlag) & LPUART_GetStatusFlags(EXAMPLE_LPUART_BASE))
    {
        uint8_t ch;
        ch = LPUART_ReadByte(EXAMPLE_LPUART_BASE);
        PRINTF("Received %c\r\n", ch);
    }

    /* If there is data to be sent */
    if ((kLPUART_TxDataRegEmptyFlag) & LPUART_GetStatusFlags(EXAMPLE_LPUART_BASE))
    {
        if (txBufferEmpty == false)
        {
            LPUART_WriteByte(EXAMPLE_LPUART_BASE, lpuartTxBuffer[0]);
            txBufferEmpty = true;
            for (uint8_t i = 1; i < EXAMPLE_LPUART_TX_BUFFER_LENGTH; i++)
            {
                lpuartTxBuffer[i - 1] = lpuartTxBuffer[i];
            }
        }
    }
}

int main(void)
{
    lpuart_config_t config;
    uint32_t uartClkSrcFreq;

    /* Init board hardware. */
    BOARD_InitPins();
    BOARD_BootClockRUN();
    BOARD_InitDebugConsole();

    /* Initialize LPUART0 pins below */
    CLOCK_AttachClk(kFRO12M_to_FLEXCOMM0);
    RESET_PeripheralReset(kFC0_RST_SHIFT_RSTn);
    CLOCK_SetDiv(kCLOCK_DivLpuartClk, 1U);

    /* Set up the LPUART config struct. */
    LPUART_GetDefaultConfig(&config);
    config.baudRate_Bps = 115200U;
    config.enableTx = true;
    config.enableRx = true;

    /* Initialize the LPUART base. */
    LPUART_Init(EXAMPLE_LPUART_BASE, &config, CLOCK_GetFreq(kCLOCK_CoreSysClk));

    /* Send data */
    LPUART_WriteBlocking(EXAMPLE_LPUART_BASE, lpuartTxBuffer, EXAMPLE_LPUART_TX_BUFFER_LENGTH);
    txBufferEmpty = false;

    /* Enable RX and TX interrupt. */
    LPUART_EnableInterrupts(EXAMPLE_LPUART_BASE, kLPUART_RxDataRegFullInterruptEnable);
    LPUART_EnableInterrupts(EXAMPLE_LPUART_BASE, kLPUART_TxDataRegEmptyInterruptEnable);

    /* Enable interrupt in NVIC. */
    NVIC_EnableIRQ(EXAMPLE_LPUART_IRQ);

    while (1)
    {
    }
}

在这个示例代码中，我们使用了LPUART0作为示例，也可以根据实际情况选择其他的串口。在main函数中，首先初始化了串口，然后将10字节的数据通过LPUART_WriteBlocking函数发送出去。在发送数据之后，我们打开了接收和发送中断，并在中断处理函数中实现连续发送数据的功能。你可以根据自己的需求修改发送的数据和发送的长度。
