LCD2.4 TFT +Touch+SDRAM

very question · Mar 4, 2013

Hi dear All
Thank you for your time
I want to use lcd TFT 2.4 with touch in my project
Would you please help me!!
Is there any library for them ?
my microcontroller is lpc1768
Thanks in advance

Hello bianchi
my lcd is TFT"2.4" with ILI9325 chip driver
where can i found this library?

Hope this will help :
You should define the port and pin yourself, depends on your chip there....

for example sbit LCD_RS = P0^0 , every uC has different style but nearly the same in my experience,

Good luck...

Code:

void Lcd_Write_Com(char VH,char VL)	 //·¢ËÍÃüÁî
{	
    LCD_RS=0;
	LCD_Writ_Bus(VH,VL);
}


void Lcd_Write_Data(char VH,char VL)	//·¢ËÍÊý¾Ý
{
    LCD_RS=1;
	LCD_Writ_Bus(VH,VL);
}

void Lcd_Init(void)
{

    LCD_REST=1;
    delayms(5);	
	LCD_REST=0;
	delayms(5);
	LCD_REST=1;
	LCD_CS=1;
	LCD_RD=1;
	LCD_WR=1;
	delayms(5);

thanks for you reply
i need schematic for how this type of lcd pins connect to microcontrollers

That's very easy....
Hope this pin assigment will help....
Anyway do you have the LCD itself in your hand ?
Because it's a waste of time if you wanna create yourself, many are sold out there...

yes I have it,I want example of that

I don't know what kind of pin configuration there, you need to find yourself, usually it's written on the board the pin function..

can you show me the photo ? so I can see ?

it's that like this

Do you know any library for this type of LCD?

Post the datasheet of TFT.

I know that,
that's the code I have uploaded before...

Could be different ? you can try yourself....

Hi
I found this Pin Description but I don't know is it true or not?
which pins for touch screen?

jayanth.devarayanadurga · Mar 11, 2013

I think it is right because pin 1 is connected to ground and pin 40 is not connected to anything.

hello ;
please anyone have a schematic for tft lcd with pic ??((how can i connect it with pic please help me ))

jayanth.devarayanadurga · Mar 29, 2013

Mention the Model of your TFT display.

what type of TFT do you want ?
Connect it to your PIC port RA, RB or RC and run the init code....

Finally I run lcd and you can see my program in continue

Now I want to work on it's screen touch,the driver of that is XPT2046
would you please help me??
