Hello,
I am trying to work with the lightcrafter 6500 in structured light mode in pre-stored images mode.
I would like to better understand the trigger in 1,2 functionality. As I understand I need to keep input 2 high to start the sequence and then use input 1 to advanced the pattern is that correct? does input 2 has to stay high for the entire sequence ?
In the documentation of the DLPC900 section 7.4.1 it says
"To synchronize a camera to the displayed patterns, the DLPC900 controller supports two pattern modes: Video
pattern and Pre-stored pattern modes. In video pattern mode, the vertical sync is used as trigger input. In prestored
pattern mode, an internal user configurable trigger or a TRIG_IN_1 pulse indicates to the DLPC900
controller to advance to the next pattern, while TRIG_IN_2 starts and stops the pattern sequence"
while in the EVM documentation it says in section 1.2.3.2
"The trigger inputs on J20 are inputs from external devices to control the pattern sequence. While trigger
input 1 is high, trigger input 2 will advance the pattern sequence to the next pattern in the sequence on
every pulse"
which one is the correct one?
Also what does it mean "an internal user configurable trigger" ?
Could you be more specific about the restriction of the trigger (duration,frequency...) ?
Thanks,
Nathan Klein.
