DLP2000: Interfacing with Android or PC

Hi Phillippe,

That was such a fast and good answer. Thank you so much. Do you know if you can you drive video through the I2C bus or is it just for configuring the system?

OK but it is now my understanding that there is no way to send RGB directly to the DLP 2000 EVM because standard RGB input won't be accepted. It requires translation and the translation board also doesn't work on the 2000. I purchased this device to accept direct video input without a Beagle Bone/PI because I read it was possible, but I see no way to actually do this. How can I send video data from a computer or phone to the projectors?

Matthew,

"It requires translation and the translation board also doesn't work on the 2000"

Can you elaborate on the above? The DLPDLCR2000EVM will accept parallel RGB888 input video (following the timings described in the datasheet. If you are interested in using, for instance, a computer or phone to input video, you will need to use a receiver to translate. One common method of doing this is implementing an ITE6801 HDMI receiver chip to drive the RGB888 lines.

Is there a particular translation board you are looking to use for your setup?

Another engineer at TI indicated that there are ways to provide direct RGB input to DLP series, but the LC 2000 is the only model that can't really do it because it doesn't have the proper RGB interpreter embedded like the other models. If there is a way to do this it would be great. How would one implement  ITE6801 HDMI  receiver chip? Are there any instructions on that?

Thanks,

Matt

Matt,

I can verify whether we have any materials regarding the ITE6801 with the DLP2000 in a different discussion thread.

In the meantime, I would suggest you start by looking at our other EVMs for some initial guidance. In particular, you will notice that our DLP2010 and DLP3010 EVMs, for example, implement their HDMI interfaces using ITE6801 chips. While the DLPC343x chipset (which is what is used in the 2010/3010 EVM) is a bit different from the DLPC2607 chipset (which is what is used with the 2000 EVM) they both accept parallel RGB888 input. This would make the core design of the interface similar in both cases.
