DLP3000: External Pattern Camera Triggering

Part Number: DLP3000

Hey everyone,

I am trying to feed an external pattern into my DLP3000 board and have it trigger the camera trigger on each bit plane.

I have done the hardware modifications (adding 0 ohm resistor to R295). In the windows GUI I can get the camera trigger working with HDMI and I see the signal when I probe the correct pins.

However, for my application I want to use the C API. Currently, my code is roughly doing this:

if(LCR_CMD_Open())
{
printf("Unable to connect to the DLP LCr\n");
}
printf("Displaying HDMI");
LCR_CMD_SetDisplayMode((LCR_DisplayMode_t)(0x02));

// Set trigger output settings
LCR_CamTriggerSetting_t triggerSettings;
triggerSettings.Enable = 1;
triggerSettings.Source = 0;
triggerSettings.Polarity = TRIGGER_EDGE_POS;
triggerSettings.Delay = 0;
triggerSettings.PulseWidth = 200; //us
LCR_CMD_SetCamTriggerSetting(&triggerSettings);

//Get trigger setttings
LCR_CamTriggerSetting_t triggerSettings;
LCR_CMD_GetCamTriggerSetting(&triggerSettings);
printf("Enable %u \n",triggerSettings.Enable);
printf("Source %u \n",triggerSettings.Source);
printf("Delay %u \n",triggerSettings.Delay);
printf("Polarity %u \n",triggerSettings.Polarity);
printf("PulseWidth %u \n",triggerSettings.PulseWidth)



This return:

Displaying HDMI

Enable 1
Source 0
Delay 0
Polarity 0
PulseWidth 200

If I probe the correct pin I can't see the camera trigger.

I was hoping someone could give me advice on what to do.
