Using Pico projector without Beagle Board

Rune Elmgaard
Prodigy 20 points

Hello,

Is is possible to use the Pico projector without the Beagle Board by just connecting it to a PC running windows XP?

I have connected it via a DVI to HDMI converter, but I have not managed to set the 640x480@60Hz mode. I'm getting a message the the output does not support the mode. Do I need som software for forcing the output mode, or is it simply not possible without using the Beagle Board for configuring the projector?

Regards,

Rune

    Rune,

    Do you have a Pico V1.0 or V2.0? The Pico 1.0 can not connect directly to a PC. It needs an EDID. EDID stands for Extended Display Information Data. This data is contained in a small EEPROM. The source device (i.e. PC) checks for the presence of an EDID prom through the DVI interface and uses the information inside the EEPROM to output the proper video format. This EDID PROM is now included in the Pico 2.0 so the user can connect the Pico directly to the PCs’ DVI port through the HDMI cable (using an HDMI-DVI adapter that is not included in the kit). The EDID PROM read over standard HDMI I/F is VGA 640 x 480 only.

    If you have a Pico V2.0, then you should be able to connect the Pico directly to a PC using the HDMI cable provided. (NOTE: The HDMI cable in the Pico V2.0 is NOT interchangeable with the HDMI cable in the Pico V1.0)

    Thanks for the clarification. Unfortunately I have the v1.0.

    Hello,

    I join this discussion a little late. To continue this conversation, I got the Pico kit 2.0 and Windows XP and Windows 7. What is the best way to make pico kit 2.0 display internal patterns in Windows XP or 7? 

    Any suggestion is greatly appreciated.

    Ku,

    Yes, this is an old thread, and some of the responses are out of date.

    I don't know that anyone has solved the problem using Windows 7 or XP. I think that someone has had success with Linux. Take a look through the threads, or do a search.

    Recently some people (Gavin Smith and Abe Karnik) have had success with using an Arduino.

    However, the best approach so far has been to use a BeagleBoard with Angstrom Linux and the i2c-tools program.

    Sorry I can't offer more about using Windows. Maybe someone reading this will have something more to add.

    Best regards,
