Some questions about DLP Pico Development kit 2.0

Hello Fangjing Hu,

Welcome to the DLP and MEMS E2E.

The Pico Kit V2 uses the DLP 0.17 HVGA Chipset. The DMD used is the DLP1700, which has an array of 480x320 mirrors with a pitch (center to center) of 7.6 microns.

The Pico Kit V2 incorporates a very compact "light engine" which contains both the DMD and the illuminating red, green, and blue LEDs. It is not possible to change these - because they are an integral part of the optics module.

If you desire to try other applications and optical arrangements you will need to start with the DLP 0.17 HVGA Chipset and construct your own illuminator and optics. Please see http://ti.com/mems for more information and access to datasheets.

hi, Pascal:

Thanks very much for your reply.

In your answer,  do you mean that i can try my own source by accessing the datasheets?

if so, it will be a encouragement for me to go forward my research work.

Fangjing Hu,

Yes. Go to http://ti.com/mems and click on the 0.17 HVGA chipset. The datasheet for the DLPC100 (the controller chip for the 0.17 HVGA chipset) has the information about the 24-Bit Input Port (RGB or BT656-YUV).

Best regards,

hi, Pascal:

Many thanks for your answer.

I try to use DLP Pico Projector Development Kit V2 as a projector in my laptop. But it seemed not recognize this device.

I want to know if I need this as a projector, is there anything else I should do before I connecting it directly to my PC?

Best wishes,

Fangjing

Fangjing,

The Pico Development Kit V2 only accepts 640x480@60Hz resolution via the HDMI (DVI-D) input. First, your computer must output either DVI or HDMI video (not VGA analog). Also, the resolution for the Pico must be set to 640x480@60Hz.

From the Windows "Display Properties" click on the "Settings" tab. Select the mointor which represents the Pico (ususally 2). Click in the box next to "Extend my Windows desktop onto this monitor". Then, set the screen resolution to 640x480. If this is not available, click on the "Advanced" button. At the next screen, click on the "Adapter" tab. Click the "List All Modes" button. Select the "640x480" resolution (there may be several color depths available. Afterwards, you should be able to go back to the "Display Properties"/"Settings" and adjust the slider for the 640x480 resolution.

I hope this helps.

Best regards,

Pascal

Hi, Pascal:

I have tried with my laptop as what you suggested. But the laptop seems cannot recognize Pico Development Kit V2.

I will try on other computers and see what happened.

I also found that http://focus.ti.com/docs/prod/folders/print/dlpc100.html:

• Input Image Size 320 × 240 (QVGA), 480 × 320
  (HVGA), or 640 × 480 (VGA)

Does it mean that the output signal of my computer should be VGA ?

Fangjing
