This adaptor board allows you to connect a [http://document.sharpsma.com/files/LQ043T3DX02_SP_122805.pdf Sharp's LQ043 LCD] to your DevLight or DevFull.<br>
The description, the datasheet and the schematics of this adaptor board [http://www.armadeus.com/english/products-peripherals-lq043_adapt.html can be found here.]

The following table summarizes the possibilities to connect the LQ043 and the Touchscreen to your development board:

This means that you have to solder several wire between the vias corresponding to the LCD signals and a free place on the board where you can add a 2x15pins header. Take a look at the Devlight datasheet. You will find a table representing the bottom side of the board. On the board (bottom), you will see a silkscreen indicating the names of each vias. In the LQ043_Adapt datasheet, you will find the pin description of the 2x15 pins connector. Connect (1 to 1) the signals of the LQ043_adapt to the ones of the Devlight.The flat cable (1) is although required || flat cable(1) connected between X5 of the LCD_Adapt and LCD connector of the DevLight [[Image:LQ043_Adapt_to_DevLightV2.jpg|thumb|Connection between DevLight V2 and LQ043]]

This  avoids developping or buying a dedicated PCB.In that case one more connection is required:
* connect LQ043 X7 pin 2 (SSI_B5) with DevLight SSI1_TxDAT. No 4 wire cable is required. The TSC2102IDA and the LM317LIDR can be purchased or shipped as samples. Take a look at here: http://focus.ti.com/docs/prod/folders/print/tsc2102.html and http://focus.ti.com/docs/prod/folders/print/lm317l.html

==(1) Flat cable==
A simple flat cable (PC like) can be used to connect the LQ043_Adapt to the [[APF27Dev]]/[[APF9328DevFull]]. If you do not have one, a ready to use cable [http://www.store.armadeus.com/index.php?language=en can be found here.] <br>
Align the pins 1 (square via) on both boards together.
'''Do not use long cables.'''

==(2) 4 wires cable ==
It is a simple one to one 4 wire cables (2.54mm single row headers on both boards: LQ043_adapt and Devfull)
