DLP3010EVM-LC: Configure Trigger Output Function

Part Number: DLP3010EVM-LC

Hi,

I am working with the DLP3010EVM-LC and the DLPC-API-1.1 on Windows 10 using VS2019 running with toolset v142

I am trying to configure the device to output a trigger signal each time it changes patterns. Here is the sequence of functions I am using in my program. Currently it successfully creates and displays images but will not produce a trigger signal from any pins in the J bank on the EVM.

InitConnectionAndCommandLayer();
CYPRESS_I2C_RequestI2CBusAccess();
WriteLookSelect(0);

/* Prepare the data for pattern data block generation */
PopulatePatternSetData(DLP3010_WIDTH, DLP3010_HEIGHT);
PopulatePatternTableData();

/* Stop pattern display */
DLPC347X_WriteInternalPatternControl(DLPC347X_PC_STOP, 0);

/* Generate and program the pattern data to the controller flash */
GenerateAndProgramPatternData(DLPC347X_INT_PAT_DMD_DLP3010);

/* Load Pattern Order Table Entry from Flash */
LoadPatternOrderTableEntryfromFlash();

/* Generate and write pattern data to a file */
GenerateAndWritePatternDataToFile(DLPC347X_INT_PAT_DMD_DLP3010, "pattern_data.bin");

DLPC347X_WriteOperatingModeSelect(DLPC347X_OM_SENS_INTERNAL_PATTERN);


//this is the line I am focusing on for this question it does not seem to show any trigger signals whether or not this line is included
DLPC347X_WriteTriggerOutConfiguration(DLPC347X_TT_TRIGGER2, DLPC347X_TE_DISABLE, DLPC347X_TI_NOT_INVERTED, 0);

//begins the pattern projection
DLPC347X_WriteInternalPatternControl(DLPC347X_PC_START, 0);

  • Hi Daniel,

    Do you have a jumper installed on J11? ( J11 - Header for voltage level selection for Trigger-in/out (Install jumper to receive output signal this is not included with the EVM ))

    This selects between a 1.8V rail and a 3.3V rail for the trigger level.

    The jumper is near the 19V power jack and is described in the EVM User Guide here


    Thank you
