Description

The DM-TFT22-102 display module, specifications and other resources are available from DisplayModule.com.

• 2.2"
• SD-card slot
• 262K color depth
• 128x160
• SPI interface
• 2 LED backlit

The display module has a 40-pin connector and requires a shield (DM-ADTAU-001) to be compatible with Arduino pinning.

Pinning

The following pins are used (not including GND and VCC) when connected to the DM-ADTAU-001 adapter:

1) For LPC1549 some hardware settings are needed. Look at http://www.displaymodule.com/pages/mbed for details.

2) The functionallity of the D10 pin is controlled with the slider on the DM-ADTAU-001 adapter board. It must be in the SD_CS position for SD Card to work. The DM-TFT22-102 does not have touch support so the T_IRQ position just disables SD Card.

Compatibility

The display module has been tested with the following platforms:

Software

There is a library to get you started with the displays:

To use the library:

#include "mbed.h"

#include "DmTftS6D0164.h"

DmTftS6D0164 tft;  /* DM_TFT22_102 */

int main() {
  tft.init();
  tft.drawString(20, 20, "x:");
  tft.drawString(100, 20, "y:");
  while(true) {
    ...
  }
}

To use the SD Card include the SDFileSystem library in your project and initialize like this:

#include "mbed.h"

#include "DmTftS6D0164.h"
#include "SDFileSystem.h"

/* Displays with adapter */
#define DM_PIN_CS_SDCARD     D10
#define DM_PIN_SD_SPI_MOSI   D11
#define DM_PIN_SD_SPI_MISO   D12
#define DM_PIN_SD_SPI_SCLK   D13

DmTftS6D0164 tft;  /* DM_TFT22_102 */

SDFileSystem sd(DM_PIN_SD_SPI_MOSI, DM_PIN_SD_SPI_MISO, DM_PIN_SD_SPI_SCLK, DM_PIN_CS_SDCARD, "sd"); // mosi,miso,clk,cs

DigitalInOut csSDCard(DM_PIN_CS_SDCARD, PIN_OUTPUT, PullUp, 1);

int main() {
  const char* fname = "/sd/logop565.bmp";

  tft.init();
  
  while (true) {
    FILE *fp = fopen(fname, "r");
    if (fp != NULL) {
      ...
    }
  }
}
