Hi guys I ´ve been trying to make some simple button with my touchscreen but some libraries confuse me.
I´d like to know in case of using my Arduino Genuino how to put the right values in this statements,as follows:
UTFT myGLCD(ITDB32S,38,39,40,41);------> this has to do with the shields pin number boards
UTouch myTouch(6,5,4,3,2);-------------------> the same thing.
My pins code header accordin to Arduino genuino is:
#define TFT_DC 9
#define TFT_CS 10
#define TFT_RST 8
#define TFT_MISO 12
#define TFT_MOSI 11
#define TFT_CLK 13
I don´t understand very well how to replace it so that the touch application can work out.
Please someone who help me
Thank you so much!
Why do people use gobbledygook names?
#define ITDB32S 2 // SSD1289 (16bit)
This seems to be a SSD1289 with a 16-bit parallel interface.
You have got zero chance of running a 16-bit TFT on a Uno.
Just count the pins.
There is even less chance of having any spare pins for a bit-banged Touch controller.
UTFT is designed for certain models of screen from specially approved manufacturers.
If you want to post a link to an approved screen, I suspect that someone can advise you.
If you post a link to an actual screen (approved or not), someone might advise you.
Your first job is to remove your shoes and socks. And get counting.

Hi David!,
WHat I just simply need is to read the pressure of my button and jump to another task.that´s all!.
I am using this TJCTM 24028 SPI module as fllows:
And I wired up like this with a modify that I made hooking up a resistor divider on each data bus:
I already have made it work out my module with this respecting this header:
#include "Adafruit_GFX.h"
#include "Adafruit_ILI9341.h"
#include "URTouch.h"
#define TFT_DC 9
#define TFT_CS 10
#define TFT_RST 8
#define TFT_MISO 12
#define TFT_MOSI 11
#define TFT_CLK 13
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_MOSI, TFT_CLK, TFT_RST, TFT_MISO);
And using URtouch I define like this:
#define t_SCK 3
#define t_CS 4
#define t_MOSI 5
#define t_MISO 6
#define t_IRQ 7
URTouch ts(t_SCK, t_CS, t_MOSI, t_MISO, t_IRQ)
And I noticed the routine that reads the pressure is:
void loop()
{
int x, y;
while(ts.dataAvailable())
{
ts.read();
x = ts.getX(); ----------> this read the pressure from touchscreen and points x,y
y = ts.getY();
}
}
What I need is to know how to modify to read a simple button on screen filled red for example so that every time I switch on it goes to another task.
Please help me!
Thanks a lot David!
My doubt is about I have to read all the pixels contained in the button or not?
Good day, Ganimides.
UTouch | URTouch libriry has the "Calibration" sketch. Use it (Correction of 3 rows in URTouchCD.h needed then) and Your touch screen will be work well.
My touch screen was mirrored before I calibrated it.
