Other Parts Discussed in Thread: DLPC350
I have tried to find the answer for this question in the DLP forum but only found a similar thread https://e2e.ti.com/support/dlp/f/94/t/378732
I'm using the DLP in pattern sequence mode to display one bit images with a fixed exposure time from an HDMI source. From what I understand the LED control is done using a PWM method. This means that, during one pattern exposure, the LED blinks very fast. This is causing big problems with my experiment.
So, I want to set the LED to a fixed current in order to avoid the blinking effect. I believe that putting the PWM value to the maximum using USB command (USB: CMD2: 0x0B, CMD3: 0x01) should put the current to a constant value. However I don't want to use the maximum current.
Is it a way to define a constant current (not maximum) for the LEDs using software or hardware? I'm following the DLPC350 Programmer’s Guide (http://www.ti.com/lit/ug/dlpu010g/dlpu010g.pdf) and using commands (USB: CMD2: 0x0B, CMD3: 0x01) and (USB: CMD2: 0x1A, CMD3: 0x07).
Best regards,
