DLPC350: DLPC设置Pattern Sequential 模式下执行Play Once时再次设置出现I2C锁死

DLPC350_StartPatLutValidate（）

这个只是验证配置数据是否有效，不是完整的pattern数据。

需要先发送配置数据, please debug it to figure out where it stopped.

void MainWindow::on_pushButton_ValidatePatSeq_clicked()

{

    int i = 0;

    unsigned int status;

    bool ready;

    if((ui->radioButton_SLMode->isChecked() == false) && (ui->radioButton_VariableExpSLMode->isChecked() == false))

    {

        ShowError("Please change operating mode to Pattern Sequence before validating sequence");

        return;

    }

    //if pattern sequence is already running it must be stopped first

    emit on_pushButton_PatSeqCtrlStop_clicked();

    //Clear the flags

    ui->pushButton_PatSeqValIndExpOOR->setEnabled(false);

    ui->pushButton_PatSeqValIndPatNumOOR->setEnabled(false);

    ui->pushButton_PatSeqValIndTrigOutOverlap->setEnabled(false);

    ui->pushButton_PatSeqValIndBlkVecMiss->setEnabled(false);

    ui->pushButton_PatSeqValPatPeriodShort->setEnabled(false);

    ui->pushButton_PatSeqCtrlStart->setEnabled(false);

    ui->pushButton_PatSeqCtrlPause->setEnabled(false);

    ui->pushButton_PatSeqCtrlStop->setEnabled(false);

    if(DLPC350_StartPatLutValidate())

    {

        ShowError("Error validating LUT data");

        return;

    }

    QEventLoop loop;

    do

    {

        if(DLPC350_CheckPatLutValidate(&ready,&status) < 0)

        {

            ShowError("Error validating LUT data");

            return;

        }

        if(ready)

        {

            break;

        }

        else

        {

            QTimer::singleShot(1000, &loop, SLOT(quit()));

            loop.exec();

        }

        if(i++ > MAX_NUM_RETRIES)

            break;

    } while(1);

    ui->pushButton_PatSeqValIndExpOOR->setEnabled((status & BIT0) == BIT0);

    ui->pushButton_PatSeqValIndPatNumOOR->setEnabled((status & BIT1) == BIT1);

    ui->pushButton_PatSeqValIndTrigOutOverlap->setEnabled((status & BIT2) == BIT2);

    ui->pushButton_PatSeqValIndBlkVecMiss->setEnabled((status & BIT3) == BIT3);

    ui->pushButton_PatSeqValPatPeriodShort->setEnabled((status & BIT4) == BIT4);

    //Except BIT0 and BIT1 flags enable pattern sequence

    if(!(status & BIT0) && !(status & BIT1))

    {

        ui->pushButton_PatSeqValStatus->setEnabled(true);

        ui->pushButton_PatSeqCtrlStart->setEnabled(true);

        ui->pushButton_PatSeqCtrlPause->setEnabled(true);

        ui->pushButton_PatSeqCtrlStop->setEnabled(true);

    }

    else

    {

        ui->pushButton_PatSeqValStatus->setEnabled(false);

        ui->pushButton_PatSeqCtrlStart->setEnabled(false);

        ui->pushButton_PatSeqCtrlPause->setEnabled(false);

        ui->pushButton_PatSeqCtrlStop->setEnabled(false);

    }

}

如果我想要自己执行多次Play Once，而不是使用内置的Repeat模式呢？命令顺序应该是什么呢？每次都要重新发送pattern的配置然后验证是否有效吗？
