DLPD4X00KIT: Download my binary patterns to the DMD( DLP4100 & DLP7000 ) with USB DLL API.

Hello Goro,

First, welcome to the DLP section of the TI-E2E forums.

Please try one thing before we get too far down the trail to help you debug.  Each time you send "LoadControl" could you send it 3 times and see if the code works then?

We will proceed from there.

Hello Fizix, thank you for your reply.

I tried 3 times of "LoadControll", but it did not change the situation.
I modified my code as follows. Is it what you aimed at?

int main()
{
	short numDevices = GetNumDev();
	short deviceNumber = numDevices - 1; // Only One device is connected.
	short dmdType = GetDMDTYPE(deviceNumber); // should be 1(DLP7000)
	
	printf("numDevices   : \t%d\n",numDevices  );
	printf("dmdType      : \t%d\n",dmdType     );
	
	//// Just for assertion .. ////
	unsigned long driverRev   = GetDriverRev(deviceNumber);
	unsigned long firmwareRev = GetFirmwareRev(deviceNumber);
	short         usbSpeed    = GetUsbSpeed(deviceNumber);
	unsigned long dllRev      = GetDLLRev();
	unsigned long fpgaRev     = GetFPGARev(deviceNumber);
	short         ddcVersion  = GetDDCVERSION(deviceNumber);
	printf("driverRev   :\t0x%08X\n",driverRev  );
	printf("firmwareRev :\t0x%08X\n",firmwareRev);
	printf("usbSpeed    :\t%d\n",    usbSpeed   );
	printf("dllRev      :\t0x%08X\n",dllRev     );
	printf("fpgaRev     :\t0x%08X\n",fpgaRev    );
	printf("ddcVersion  :\t0x%04X\n",ddcVersion );
	///////////////////////////////
	
	
	SetWDT(0, deviceNumber); // Disable WDT
	SetPWRFLOAT(0, deviceNumber); // Disable Power Float
	SetTPGEnable(0, deviceNumber); // Disable TestPatternGenerator

	FILE *fp = fopen("../../TMGenerator/C++/Result/S1DMD-0001.bin", "rb"); // load my own pattern
	unsigned char rowData[(1024 / 8) * 768];
	fread(rowData, sizeof(rowData), 1, fp); // prepare DMD pattern data from bin file.
	fclose(fp);

	SetBlkMd(0, deviceNumber); // DMD Block Operations -- NOP
	LoadControl(deviceNumber); // DMD Block Operations -- Execute!
	LoadControl(deviceNumber); // DMD Block Operations -- Execute!
	LoadControl(deviceNumber); // DMD Block Operations -- Execute!

	ClearFifos(deviceNumber); // Initialize the DMD fifo.
	LoadData(rowData, sizeof(rowData) / 2, dmdType, deviceNumber); // Load 1st half of pattern int the DMD.
	LoadData(rowData + sizeof(rowData) / 2, sizeof(rowData) / 2, dmdType, deviceNumber); // Load last half of pattern int the DMD.

	SetBlkMd(3, deviceNumber); // DMD Block Operations -- Global Reset Requet
	SetBlkAd(8, deviceNumber); // BLK_AD=4'b10xx
	LoadControl(deviceNumber); // // DMD Block Operations -- Execute!
	LoadControl(deviceNumber); // DMD Block Operations -- Execute!
	LoadControl(deviceNumber); // DMD Block Operations -- Execute!

	return 0;
}

From above code, I got these values. Are there anything suspicious?

numDevices   :  1
dmdType      :  1
driverRev   :   0x010303E7
firmwareRev :   0x00000200
usbSpeed    :   1
dllRev      :   0x00020001
fpgaRev     :   0xAC02230C
ddcVersion  :   0x0007

Hello Goro,

Yes, that is exactly what I had in mind.  This confirms that it is probably not a timing issue.

I will need to look a little closer at your code.  I should have a response in the next day or so.

Hi FIzix, thank you for your support.

Now I managed to display my own pattern on the DMD.
There were 2 problems.
One was lacking of RowMd operations before executing "LoadData" function, and another was executing "SetPWRFLOAT".

I modified my code as follows. Please have a look at it, if I still made other mistakes or not.

int main()
{
	short numDevices = GetNumDev();
	short deviceNumber = numDevices - 1; // Only One device is connected.
	short dmdType = GetDMDTYPE(deviceNumber); // should be 1(DLP7000)

	SetWDT(0, deviceNumber); // Disable WDT
//x	SetPWRFLOAT(0, deviceNumber); // Disable Power Float
	SetTPGEnable(0, deviceNumber); // Disable TestPatternGenerator


	FILE *fp = fopen("../../TMGenerator/C++/Result/S1DMD-0001.bin", "rb"); // load my own pattern
	unsigned char rowData[(1024 / 8) * 768];
	fread(rowData, sizeof(rowData), 1, fp); // prepare DMD pattern data from bin file.
	fclose(fp);

	SetBlkMd(0, deviceNumber); // DMD Block Operations -- NOP
	LoadControl(deviceNumber); // DMD Block Operations -- Execute!

	SetRowMd(3, deviceNumber); // Set First row address
	SetNSFLIP(0, deviceNumber); //
	LoadControl(deviceNumber); // Row Operations -- Execute!

	SetRowMd(1, deviceNumber); // Increment internal row address by 1
	SetNSFLIP(0, deviceNumber); //
	LoadControl(deviceNumber); // Row Operations -- Execute!

	ClearFifos(deviceNumber); // Initialize the DMD fifo.
	LoadData(rowData, sizeof(rowData) / 2, dmdType, deviceNumber); // Load 1st half of pattern int the DMD.
	LoadData(rowData + sizeof(rowData) / 2, sizeof(rowData) / 2, dmdType, deviceNumber); // Load last half of pattern int the DMD.

	SetBlkMd(3, deviceNumber); // DMD Block Operations -- Global Reset Requet
	SetBlkAd(8, deviceNumber); // BLK_AD=4'b10xx
	LoadControl(deviceNumber); // // DMD Block Operations -- Execute!

	return 0;
