Projector question #7

Closed nikkadim closed 7 years ago

nikkadim commented 7 years ago

Hi Jacob, First of all thank you for all your hard work, I'm trying to follow your steps, and I have question about Projector setup. I have:

but when I run ProjectorTest from ~/slstudio/slstudio-master/src/projector it's shows `Screen 0: width 2624, height 900
terminate called after throwing an instance of 'char const*' also wondering should I upgrade the projector firmware first(now v.2.0.0) and may be preset-up it? Because right now it shows patterns in red via USB (and in B/W via HDMI), but I want to trigger camera, so I need USB mode.

You need to follow the instructions for X Screens setup in the readme.

Sorry, but I still have a problem with Lightcrafter4500 connected via USB/API, I have latest FW (v3.0.0) and I can see it (have a right udev rules):

Bus 002 Device 003: ID 2676:ba02 Basler AG ace
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 0451:6401 Texas Instruments, Inc. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

and SLstudio can communicate with projector too, ProjectorLC4500: preparing LightCrafter 4500 for duty... but it looks like I missed something and it needs to pre-setup projector somehow!?

screenshot from 2016-10-20 12-00-02 because when I start calibration process all i see is the flickering TI logo in red like that: unnamed

Thank you for your help.

When using the LC4500 API, the patterns for the Pattern Mode you plan to use need to be stored in the firmware of the projector. Currently, this is a manual process and the TI e2e forum is the place to get support in that regard.

Instead of choosing "LC4500 API" in the Preferences, you just select the 'Screen' that is presented as the projector. Then run the projector in Pattern Sequence mode (using the Lightcrafter GUI from TI).
