PLATFORM SETUP INSTRUCTIONS

The MQ-1132 / PCI Evaluation Board is used in conjunction with a motherboard with a PCI interface. The followings components are required :

§ A complete PC motherboard system containing a PCI interface slot

§ A flat panel (i.e. Sharp HR TFT- LQ039Q2DS54)

§ Windows 2000/NT

FUNCTIONAL DESCRIPTION

Flat Panel Interface

The MQ-1132 / PCI Evaluation board has two connectors intended for interfacing to a variety of flat panel displays. Connector U12 is used to interface directly to a Sharp HR TFT display (LQ039Q2DS54). The MQ-1132 evaluation board has all the necessary power and power sequencing circuitry necessary for this panel. Following are directions to connect the flat panel cable to the evaluation board:

§ Lift the brown lever on the HR TFT socket (U12)

§ Insert the flat cable with the exposed portion facing up over the lever and under the top of the

socket

§ Push down the brown lever – this should lock the cable into place and make electrical connection

Also provided, is a Generic Flat Panel connector (JP1) that can be used to interface the evaluation board to panels other than the Sharp HR TFT. Custom cables are required to map the panel signals onto the proper MQ-1132 pins. The cable requires a matching female connector to mate with the 60-pin, 50-mil, 2x30 male connector on the evaluation board. The part number for the female connector is M50-

MQ11XX INITIALIZATIO N

The following files are needed to run the initialization test for the MQ1132 /PCI evaluation board. These files should be included in the package.

• MQ11xxTest.exe

• MQ11xxPCI.dll

• MQPCI.dll

• MQPCI.sys.

MQ11xxTest program should be run under WindowNT/2000.

The command is:

MQ11xxTest <PanelType> <Bpp>

Revision A 4/12/01 Preliminary

MQ-1132 / PCI Evaluation Board Users Guide MediaQ Incorporated

Board Revision 2

Where PanelType is 1-10 (described in the MQ11xxTest procedures) and Bpp is either 8Bpp or 16Bpp.

The MQ11xxTest utility is available through our Sales or Field Applications group.

Touch Screen / MMC

The evaluation board supports two functions o n the SPI interface. Only one device is selected at a time by software setting two GPIO pins that control a multiplexer on the board. One of the functions is a touch screen controller and the other is a Multi-Media Card (MMC) socket.

For the touch scree n, two connectors are provided on the board to interface with various devices. J12 mates with the flat cable connected to the touch panel provided with the Sharp HR TFT display (LQ039Q2DS54). To install the cable, pull out the sliding black portion of the socket, insert the cable bare metal side up and then push the black portion back in locking the cable in place.

The other connector (J11) is a 1x4 0.1” standard header that can be used to interface to other touch screens. A custom cable is required to connect a touch screen to J11. The pin out of this connector is shown below (note, this touchscreen controller only supports standard 4-wire resistive touchscreens):

USB

Two USB connectors are provided on the evaluation board. CN2 is a Type A USB connector and provides the USB Host functionality of the MQ -1132. CN1 is a Type B connector and provides the USB Device function. Since the MQ -1132 USB device is a high speed device, CN1 is configured as such.

Audio

The evaluation board supports audio input and playback/output. Audio input can come from any amplified audio source and uses the Phone Jack J1. If a microphone is used it must be an amplified version. Amplified audio output to headphones, amplified speakers or other destination is available on the other Phone Jack at J2.

Power

Power is provided by the PCI interface and is regulated on the MQ -1132/PCI Evaluation board.
