TFT LCD controller library

rezaf · Dec 28, 2013

Hi,

I have an 2.4" TFT LCD Module with touch screen that I think the LCD's controller chip is S6D1121. I want to connect it to my At91SAM7X board but can't find any library for it. can you help me to find right header and library for it (most of libraries in the web are for arduino, firewire or are UTFT-base or other structures)?

Thanks.

You can not hope every chip have unique library just fit your controller.
Generally, you need make some modification based on current library to fit your needs.
It is not very complicated, I suppose.

this links has Modules that is similar to my module (the only thing that differ is this that the serial number in back of my LCD ends with 101014-HLY-B-1121 and don't end with S6D1121):

I can't really understand why this similar modules has multiple controller chips.
I written this header with helping of arduino header but not work yet and I don't know really what is the controller of my LCD module.

Code:

#include <Headers\AT91SAM7X256.H> 
#include <Headers\delay.h>

I give you a suggestion: do not use any LCD module without any resources, do not kill time on them. It may saved you pennies, but cost your much more time, which I think is valuable.

rezaf · Dec 30, 2013

Yes you are right, but this is the only LCD that has my required dimension and resolution (in the markets of my location) and also has a few resources in the web.

jigshaw · Dec 31, 2013

It is only a 2.4" dimension TFT LCD with resolution 320*240, very common part for mobile phone in early years. It won't be difficult to find substitutes.

HsiueMingLee · Jan 1, 2014

if you wanna get a tft library , i think it is impossible . you could find the tft register user mannual ,an find out key regester to program and write your own library .

rezaf · Jan 27, 2014

I written the library with usage of libraries in the web but with changing the InitLCD and SetXY and SetPixel functions and the library worked. with this work I found that I can work with every LCD and controller but with a few changes in this 3 functions because other functions only use this 3 functions to work.

khalidabdo · Aug 19, 2015

pleas i need the link that you followed to get library.
