Description

Note Note: The Chimei LW700AT has been replaced by the ST0700_adapt board.


This adapter board allows you to connect a LCD to your DevFull.
The following table summarizes the possibilities to connect the LQW700AT and the Touchscreen to your development board:


APF27Dev
TFT usage flat cable (1) connected between J10 of the APF27Dev and X5 of the LCD_Adapt
Connection between APF27Dev and LW700_Adapt
Touchscreen usage All touchscreen signal are provided by main flat cable.


(1) Flat cable

A simple flat cable (PC like) can be used to connect the LW700_Adapt to the APF27Dev. If you do not have one, a ready to use cable can be found here.
Align the pins 1 (square via) on both boards together. Do not use long cables.
