The 7” LCD module ships with:  

  •  Interface cable (used to connect the module to the Topaz Development Kit)  
  •  Mounting Kit (screws and spacers in a small plastic bag) 

The 7" LCD module uses a 800x480 panel which includes a touch-screen. 
The Topaz LCD modules includes an ID chip (EEPROM conected via I2C), so the Operating System knows which display driver to use.  

Mounting Options

There are two mounting options for the display:

  1. Side-by-side

This is best if you need to attach things
to the Topaz expansion headers

2. Mounted

Mount the LCD board to theTopaz Dev Kit
using the supplied screws and spacers.

Connecting the LCD to the TDK

For both options, you need to connect the LCD board and the dev kit together. 
Follow these steps:

AttachingCableToTopaz1-small

On the bottom of the Topaz Dev Kit
you will find the LCD connector.
Open this and place the cable
with the black side facing up. 

AttachingCableToTopaz2-small

Insert the cable into the connector.

AttachingCableToTopaz3-small

Close the connector.

AttachTo7-1-small

Place the LCD face-down and
line up the cable and connector J1 

AttachTo7-2-small

Insert the cable into the connector

AttachTo7-3-small

Close the connector

Turn both boards cover and you are ready to power up and test the connection.

The touch-screen calibration is usually close enough to enable you to operate a new board straight away. 

 If it is not accurate, recalibrate in Windows CE by selecting Start->Settings->Control Panel.  Double-tap the Stylus icon and select the calibration tab.  Press the Recalibrate button and follow the on-screen instructions.   

 If you need the side-by-side configuration, then there is nothing more to do! 

 

Mounting the TDK and 7" LCD

The LCD kit box includes a small bag with 4 screws, 4 large spacers and 4 small spacers. 

MountingKit-small

Follow these steps to mount the LCD board on the Development Kit: 

Mounting7-1-small

Turn the LCD and development kit over
and place the small spacer over the
mounting holes. 

Mounting7-2-small

Flip the Topaz board over and position
it above the LCD board. Insert a screw
into a large spacer and insert this
into one of the mounting holes. 

Mounting7-3-small

Add the remaining screws and spacers
to complete the mounting. Turn the board
over and power on to verify everything
is running OK.
