器件型号： DLPNIRNANOEVM
主题中讨论的其他器件： DLPC150

开发光谱仪时、DLPC150 的内部测试模式已经过调试并正常工作。然而、当为外部 RGB 信号配置 DLPC150 时、每次写入配置时、都会首先使用 0xD3 命令读取通信状态、然后使用 0xD0 命令读取短状态。 DLPC150 以这种方式按顺序配置。问题是 0xD3 和 0xD0 返回的状态不一致（请参阅下面的屏幕截图）。配置代码如下所示：

				if(dlpc150_imageCrop() != PASS)
				{
            debug_print("  Failed to set dlpc150_imageCrop\r\n");
            return FAIL;					
				}
				vTaskDelay(200);
        debug_print("  Configuring for RGB port input mode...\r\n");
        dlpc150_GetCommunicationStatus();
				vTaskDelay(200);
				DLPC150_GetShortStatus(&states);
				debug_print("ShortStatus = %x\r\n",states);
				vTaskDelay(200);
        if (dlpc150_SetDefaultDisplaySize() != PASS)
        {
            debug_print("  Failed to set default display size\r\n");
            return FAIL;
        }
				vTaskDelay(200);
        debug_print("  Set default display size\r\n");
        dlpc150_GetCommunicationStatus();
				vTaskDelay(200);

            return FAIL;
        }

				vTaskDelay(200);        
        source = INPUT_SOURCE_RGB;  // 0x00
        if (dlpc150_inputSourceSelect(source) != PASS)
        {
            debug_print("  Failed to select RGB source\r\n");
            return FAIL;
        }
				vTaskDelay(200);
        debug_print("  Selected RGB source\r\n");
				dlpc150_GetCommunicationStatus();
				vTaskDelay(200);

				debug_print("ShortStatus = %x\r\n",states);
				vTaskDelay(200);

        {
            debug_print("  Failed to Set SyncPolarity\r\n");
            return FAIL;
        }
				vTaskDelay(200);
        debug_print("  success to Set SyncPolarity\r\n");

        if (dlpc150_SetHWLockMode() != PASS)
