Hello Abhishekh,

Yes, you should be able to use Beagleboard.

I am curious to know about your application, since there is already DM365 on the Kit, you can develop or port your application directly on it. You can use DVSDK http://www.ti.com/dlplcr_dm365_dvsdk_v5

If you still see importance of BeagleBoard, all you need to do if get the following things setup on the BeagleBoard.

1. TCP Clinect (over USB gadget) to talk to LightCrafter.

2. Digital output (Over HDMI connector) - generate video in 608x684 resolution format. If you are using Pattern Display Mode else any popular resolution listed in the DLPC300 Programmer's Guide I2C register 0x0C.

Sanjeev

Hello Sanjeev,

Thanks for the information. I need to capture image from a Webcam and project after some image processing. Is that possible with lightcrafter alone? can make it a standalone system ?

with DM365, image processing is possible ?

Hi,

On the LightCrafter Kit, there is one miniUSB port that is used to as TCP communication interface with the PC.

So there is no spare USB port to talk to Webcam.

As you know kit has on-board Parallel Port (MIPI interface) for talking directly to any SOC camera modules. But all this requires your familarity with Linux Device driver, camera driver and hands-on with DVSDK. This another option if you are comfortable with.

Hi Sanjeev,

I'm not familiar with Linux device drivers.

As you suggested, with MIPI interface I can connect camera module to LightCrafter Kit. For processing image, should I do coding over DM365 ?.

Hello Abhishekh,

Yes, unless you are familiar with the camera interfacing on Linux it would be difficult.

About camera there is a discussion on the E2E thread http://e2e.ti.com/support/dlp__mems_micro-electro-mechanical_systems/f/850/t/321948.aspx

There is a basic camera interface working code in the official build but it is configured to read the 8bpp camera frames.

HI Sanjeev,

How about image processing ? How can I do processing of captured video from camera? Is that possible by coding DM365?

Will you supply control boards for Optical engines separately?

Hello Abhishekh,

Why not, you should be able to do the image processing. It depends upon your familiarity with Linux and device driver development you may end up spending long time.

TI doesn't sell the Optical engine directly you can look on the http://www.ti.com/lsds/ti/analog/dlp/solutions-services.page for possible optical vendors.

The easiest way would be connect camera to PC and control the LightCrafter via GUI or using sample code provided here http://www.ti.com/tool/dlplightcrafter in latest packages.
