它的启动正常。

 毫米波回调函数为：

static int32_t MmwDemo_eventCallbackFxn(uint8_t devIndex, uint16_t msgId, uint16_t sbId, uint16_t sbLen, uint8_t *payload)
{
    uint16_t asyncSB = RL_GET_SBID_FROM_UNIQ_SBID(sbId);

    /* Process the received message: */
    CLI_write("[Msg Id: 0x%x] [Sub Block Id: 0x%x]\n", msgId, asyncSB);

打印

Done

aoaFovCfg -1 -90 90 -90 90

mmwDemo:/>
sensorStart

此外、我在 MSS 中添加了一个 frameStart ISR、

#define WAVEFORM_CFG_INTR   CSL_MSS_INTR_DFE_FRAME_START_TO_MSS

static void frame_start_ISR (void *arg)
{
    // int32_t         errCode;
    // MMWave_MCB*    ptrMMWaveMCB = (MMWave_MCB*)arg;
    // updateAdvChirpCfg(ptrMMWaveMCB, &errCode);
    gFrameCounter++;
    SemaphoreP_post(&gMmwMssMCB.UartExportSemHandle);

    HwiP_clearInt((uint32_t)WAVEFORM_CFG_INTR);
    return;
}

int32_t register_frame_start_intr(MMWave_Handle ptrMMwaveHandle)
{
    int32_t           retVal = 0;
    int32_t           status = SystemP_SUCCESS;
    HwiP_Params       hwiPrms;

    HwiP_Params_init(&hwiPrms);
    hwiPrms.intNum      = WAVEFORM_CFG_INTR;
    hwiPrms.callback    = &frame_start_ISR ;
    hwiPrms.args        = (void *)ptrMMwaveHandle;
    status              = HwiP_construct(&frameStartHwiObject, &hwiPrms);

    if(SystemP_SUCCESS != status)
    {
        retVal = -1;
    }
    else
    {
        HwiP_enableInt((uint32_t)WAVEFORM_CFG_INTR);
    }

    return 0;
}

如果 frameStart INTR 出现、它应在 mmwDemo_mssUartDataExportTask 中打印 frameCnt

void mmwDemo_mssUartDataExportTask(void* args)
{
    while (1)
    {
        /* Export the Data: */
        CLI_write ("Frame: %d\n", getFrameCounter());
        SemaphoreP_pend(&gMmwMssMCB.UartExportSemHandle, SystemP_WAIT_FOREVER);
        if ((gMmwMssMCB.ptrResult.size[0]) == sizeof(DPC_ObjectDetection_ExecuteResult)){
            MmwDemo_handleObjectDetResult();
        }
    }
}

但似乎没有帧触发、毫米波报告没有错误。

波形配置出了什么问题、如何 解决这个问题。
