DLP4710EVM-LC: 关于dlpc347x_samples示例的问题，如果我调用任何写入相关的函数，程序就无法重复运行，必须断开投影仪的电源才能恢复

1.我用一个循环重复运行投影仪的示例代码dlpc347x_samples.c

//dlpc347x_samples.c
//main函数while (true){InitConnectionAndCommandLayer();bool Status = CYPRESS_I2C_RequestI2CBusAccess();if (Status != true){printf("Error Request I2C Bus ACCESS!!!");return;}DLPC34XX_ControllerDeviceId_e DeviceId = DLPC34XX_CDI_DLPC3479;DLPC34XX_ReadControllerDeviceId(&DeviceId);printf("Controller Devicde Id = %d \n", DeviceId);uint16_t PixelsPerLine, LinesPerFrame;DLPC34XX_ReadInputImageSize(&PixelsPerLine, &LinesPerFrame);printf("Input Image Size = 0x%x, 0x%x \n", PixelsPerLine, LinesPerFrame);LoadPreBuildPatternData();LoadPatternOrderTableEntryfromFlash();DLPC34XX_WriteTriggerOutConfiguration(DLPC34XX_TT_TRIGGER2,DLPC34XX_TE_ENABLE, DLPC34XX_TI_NOT_INVERTED, 0);DLPC34XX_WriteOperatingModeSelect(DLPC34XX_OM_SENS_INTERNAL_PATTERN);DLPC34XX_WriteInternalPatternControl(DLPC34XX_PC_START, 0x0);WaitForSeconds(3);if (CYPRESS_I2C_RelinquishI2CBusAccess()){printf("RelinquishI2CBusAccess\n\n");}}

运行结果如下，循环只成功执行了一次，随后卡住约10分钟自动退出

经过debug，发现代码在第二次循环调用CYPRESS_I2C_RequestI2CBusAccess()函数时，陷入在该函数的循环里，直到超时

//cypress_i2c.c//bool CYPRESS_I2C_RequestI2CBusAccess()while ((time(NULL) - StartTime) < I2C_TIMEOUT_MILLISECONDS){//printf("%d", &Value);if (!CYPRESS_I2C_GetCyGpio(I2C_ACCESS_GRANTED_GPIO, &Value)){break;}if (Value == 1){if (!CYPRESS_I2C_SetCyGpio(START_I2C_TRANSACTION_GPIO, 1)){break;}CyI2cReset(s_Handle, false);CyI2cReset(s_Handle, true);return true;}}

2.后来我将主函数下的所有关于写入的函数注释掉，并再次运行，代码如下

//dlpc347x_samples.c
//main函数，移除写入操作while (true){InitConnectionAndCommandLayer();bool Status = CYPRESS_I2C_RequestI2CBusAccess();if (Status != true){printf("Error Request I2C Bus ACCESS!!!");return;}DLPC34XX_ControllerDeviceId_e DeviceId = DLPC34XX_CDI_DLPC3479;DLPC34XX_ReadControllerDeviceId(&DeviceId);printf("Controller Devicde Id = %d \n", DeviceId);uint16_t PixelsPerLine, LinesPerFrame;DLPC34XX_ReadInputImageSize(&PixelsPerLine, &LinesPerFrame);printf("Input Image Size = 0x%x, 0x%x \n", PixelsPerLine, LinesPerFrame);//LoadPreBuildPatternData();//LoadPatternOrderTableEntryfromFlash();//DLPC34XX_WriteTriggerOutConfiguration(DLPC34XX_TT_TRIGGER2,//DLPC34XX_TE_ENABLE, DLPC34XX_TI_NOT_INVERTED, 0);//DLPC34XX_WriteOperatingModeSelect(DLPC34XX_OM_SENS_INTERNAL_PATTERN);//DLPC34XX_WriteInternalPatternControl(DLPC34XX_PC_START, 0x0);//WaitForSeconds(3);if (CYPRESS_I2C_RelinquishI2CBusAccess()){printf("RelinquishI2CBusAccess\n\n");}}

此时运行结果如下，循环正常运行

3.经过debug，我发现只要程序经DLPC_COMMON_SendWrite()函数成功写入过数据，主函数循环就只能执行一次。只能通过断电重置投影仪，再次运行出现同样的问题

这意味着投影仪无法正常待机，我每次使用投影仪必须先断开电源，请问如何解决？
