hi we need to know what linux is runing on DM365 is it montavista or not? Also how video is generated for the projection, do we send data to FPGA and it generates Parallel RGB or we can generate parallel RGB on DM365 and send it directly to DLP chip (basically send video to the scree on linux and have it outputted on the projector)
Matt,
LightCrafter is running Linux 2.6.32. It is basically a modified version of this DVSDK release, customized for LightCrafter:
The FPGA acts as mux between the HDMI video data and DM365. Thus, the DM365 can generate 24-bit RGB and send it to the FPGA. The FPGA re-routes this to the DLPC300. We have not yet developed the V4L2 driver to support LightCrafter. This would be needed to send the Linux video output to the projector. An application is running on DM365 to produce the colored bar pattern. This pattern was created by writing directly to the video processing RGB output port.
Thanks!
can you also comment on this please?

"Do we have source code for that application so we can see how to write data to "RGB port". Also to simplify things, if we have something we want to output on the screen (assuming like regular display on Linux or program with graphical output) how would we do that?

Dear Pedro,
My question relating to the Light crafter is how can I build a simple projector which will turn on and immediatly play a video in a loop on an SD card with out showing a logo or menu function as all the products out there using DLP displays a logo and then takes 15 seconds to go through a menu before you can play the video. I am looking for a solution for my highly specialized application and it doesn't seem that I can do this with the lightcrafter kit. CAn youhelp me?
Thank you,
Matt
LightCrafter boots embedded Linux, so it takes about 15 second to boot up. Once we release the MSP430 and DM365 software to the open source, you could create a custom software that does not use Linux and reads the SD card and plays a video. The MSP430 software sets the initial splash screens through an I2C command. Once the MSP430 software is available, you can remove the display of the four splash screens. In the meantime, you can send an I2C curtain command that blocks the display of the image in the DMD. See Display Curtain Control (I2C: 0xA6) command in the DLPC300 Programmer's Guide.
Does the onboard distro include python?
