Other Parts Discussed in Thread: DLP7000,
Hello,
I have noticed a behavior I can't find documentation for using the D4100 Explorer GUI for controlling a DLP7000 (0.7 XGA 2xLVDS Type-A DMD: 1024x768 resolution) part via a DLPLCRC410EVM board.
I am probing test point 28 (an MBRST line) and have observed what appears to be a second mirror clocking pulse after the initial (expected) pulse. This pulse occurs approximately 7ms after the initial pulse and seems to have some variability on the exact time delay between pulses. I should also note that it seems to not always appear on every frame load.
See below for scope traces of the behavior in question.
What is this? Is this documented somewhere and I cannot find it?
This is the information form the about page of the D4100 GUI:
This is the GUI script I have been using for toggling at a 50/50 duty cycle of all on, all off, with a second between frames.
Discovery 4100 Explorer Script, SW Version 2.1.0, 10/2/2019

The images used are simply either all white (all_on) or all black (parallel) 1024x768 bitmaps.
Any insight on this matter would be appreciated.
Thanks for you help,
