Arduino Shield - 2.4" TFT LCD Touch

Er zijn verschillende 2.4″ shields TFT LCD Shields in omloop van MCUfriend.com met diverse aansturende chips, er moet veel uitgeprobeerd worden om te achterhalen welke driver ID er gebruikt wordt.

Deze zien er zo uit:

Fix mirrored text (example MCU friend library)

Sometimes you may wind up with mirorred text:

To correct this, you need to flip the axis and rotate the screen 180 degrees, the steps:

edit file MCUFRIEND_kbv.cpp , search for case 0x9341: add the INVERT_GS command to the _lcd_capable instruction:

Save the file, and you are ready, next to rotate 180 degrees enter the rotation command in your code to 2

tft.setRotation(2);

this will fix your mirror view ;-)

Touchscreen issues and calibration

One thing that you should note when using this library is that when you upload the code and start your touchscreen module. You might notice that your touchscreen is not working. Don’t panic it is probably because the pins are not correct. The pins were changed around a little so in my case. In your Arduino touchscreen sketch change the pins as below:
#define YP A3
#define XM A2
#define YM 9
#define XP 8

you can also look at the schematic (if provided) for the pinout on the module that you bought.

The next problem I ran into is that the coordinates are messed up for my module. Luckily, you can change the configuration by editing this file : SPDF5408_Touchscreen.cpp. In there locate this line of code: return TSPoint(1023 – x, 1023 – y, z);
for me it got it working with this settings: return TSPoint(x,y-50,z); you can play around with these values to get your desired result.

I was unable to find a programming datasheet for the lgdp4535 but I did turn-up some code for a different micropocessor platform that made this possible.
So this is a hack of the “Adafruit_TFTLCD” library where the ILI9341 initialisation valuse are replace with the values for the lgdp4535 and the library is initalised forced to use the ILI9341.

To do this modify “Adafruit_TFTLCD.cpp” and replace the array “ILI932x_regValues” with the following:

static const uint16_t ILI932x_regValues[] PROGMEM = {
  
      0x15, 0x0030,     /* Set the internal vcore voltage */                                              
     0x9A, 0x0010,     /* Start internal OSC */
      0x11, 0x0020,        /* set SS and SM bit */
      0x10, 0x3428,        /* set 1 line inversion */
      0x12, 0x0002,        /* set GRAM write direction and BGR=1 */ 
      0x13, 0x1038,        /* Resize register */
      TFTLCD_DELAY, 40, 
      0x12, 0x0012,        /* set the back porch and front porch */
      TFTLCD_DELAY, 40, 
      0x10, 0x3420,        /* set non-display area refresh cycle ISC[3:0] */
      0x13, 0x3045,        /* FMARK function */
      TFTLCD_DELAY, 70, 
      0x30, 0x0000,      /* RGB interface setting */
