Hi,

This is my first discussion in this community forum.

I am using Wandboard-Quad Revision C1.

OS:- Android 4.4.2

Kernel version:- 3.0.35

I am trying to use LCD which made by KYOCERA Industrial Ceramics Corporation - Display Division.

Product code is 'T-55343GD035JU-LW-AEN'

http://www.kyocera-display.com/products/partdetail.asp?PartNumber=T-55343GD035JU-LW-AEN

 

I found datasheet by following Link:-

For touch panel i use ADS7846 TOUCH SCREEN CONTROLLER which found at http://www.ti.com/product/ads7846,

By technical documentation http://www.ti.com/general/docs/lit/getliterature.tsp?genericPartNumber=ads7846&fileType=pdf

Its 16,14,12,15 no.pins i connect to Wandboard's Carrier boards JP4 11,7,9,13 respectively by using one custom extension PCB which used between Wandboard & LCD.

 

All other details in following link where i asked question in Wandboard forum:-

Wandboard Discussion Forums • View topic - How to use ADS7846 Driver for Touch panel?
