Trigger Controls; Image Load Timing - Texas Instruments DLP LightCrafter 4500 User Manual

A typical time is 200 ms. Once an image is loaded from flash, 24 bit-fields reside in the frame buffer and
can be sequenced at higher speeds. Two 24-bit field display buffers are available in the DLPC350. If the
pattern sequence uses more than two images (48-bit fields), then approximately 200 ms is required to
load the new image into the DLPC350 internal display buffer.

3.3.4 Trigger Controls

The Trigger Controls subtab sets the polarity and adjusts the rising and falling edge delay of the trigger
inputs and outputs, see
• TRIG_IN_1:
– Trigger 1 In Delay: Sets the rising edge delay of the DLPC350 TRIG_IN_1 signal in relation to the
display of the pattern on the DMD. Each number adds 107.136 ns. The GUI allows for delay ranges
between 0 µs and 28084.95 µs, but for more information on how to extend the delay range, see the
DLPC350 Programmer's Guide
• TRIG_OUT_1:
