TFT LCD with HX8347

good

Hi, which pins in shield correspond to RD, WR, RS, CS and RESET? Tanks

Hi, my question are the fisical pins in the shiel, I bought one of this but seems to have diffenrent configuaration on pins . Pins 21 to 26 are for the touch control, from 27 to 34 are DB0-DB7 and 38 RD Can you confirm this? I´ve connected my tft but it´s happening something strange, when I do a reset on mbed TFT goes black, that it starts slowly to become withe, than stays withe

Any ideia? Tanks

Hi, it is the same for me, LCD is not working. checked my connections as well

Hi Vitor, I believe your LCD has a different controller, although they look similar.

check this link http://www.emartee.com/product/41608/TFT-2.4%22-320*240-With-Touch-Shield-%28Arduino-Compatible%29

So, where can this particular LCD be purchased?

May you send me the PCB drawing, please?

Hey There's a new GREAT serial LCD board for development, doesn't require all the 16-24 pins of the mbed like the LCD mentioned here, it just need TX and RX, and could be mounted on a standard breadboard!, VERY EASY!

Hello Emmanuel,

thanks for promotion of new homepage. It seems this is your product and homepage. Please promote some real view picture of display, so that I can see qualitity of display and resolution. Have you realized some menues or pictures on display? Thanks.

Hi Dirck

Of course I have pictures and menus and all kind of applications, check our cookbook page http://mbed.org/cookbook/SMARTGPU and there's a video of an ipod like application made on SMARTGPU, all the source code and library are available too!

Another option is to use eg the MCP23S17 in the data bus, allowing work to 10MHz Clock in SPI. It greatly reduces the number of pins used and you get good data transfer speed. Cheapest option.

Unable to get this to work. Using a 3.2" lcd display with a HX8347A controller and verified my connections.

Looks like this library is actually for the SSD1289, judging by the init code. Luckily my LCD is an SSD1289. Funny thing is that the eBay auction I got it from claimed it to be a HX8347.

I couldn't get it to work without a delay between the WR toggle:

void LCDTFT::vLCDTFTWriteData(unsigned short Data){
    LCD_PIN_RS=1;
    LCD_PIN_CS=0; 
    LCD_PORT->write(Data);   
    LCD_PIN_WR=0; 
    
    short i;
    for(i=0; i<9; i++) {
        __nop();
    }
    LCD_PIN_WR=1; 
    LCD_PIN_CS =1; 
}

.. probably because I am using a breadboard, which has unwanted capacitance etc. It won't work for any loop value less than 9!

I have the same tft with controller SSD1289, its working fine with the library when trying to write text,drawing circles or rectangles , but unable to display bitmap image. i tried to copy the bitmap image with name "IMG0.BMP" into the mbed usb folder.

but i did n`t get any image displayed. if anyone know how to display image please guide me.
