Cod sursa 2.4 TFT LCD Shield

[vasile eugen]

Saluare.Sunt la inceput de drum cu acest sistem de dzvoltare.Am achizitionat un Arduino uno R3 impreuna  cu displaiul amintit in titlu.Am incercat coduri din saitul:http://nicuflorica.blogspot.ro/search?updated-min=2014-01-01T00:00:00%2B02:00&updated-max=2015-01-01T00:00:00%2B02:00&max-results=50

Dar nimic.Am  incercat sa fac din programe gasite si  in forma  copy/paste dar imi dadea erori la compilare.Am descarcat si librari si le-am pus  in fisierul librari de la arduino dar nimic.Ma poate ajuta cineva  cu un cod pentru  atesta TFT-ul?Pe display 2*16 caractere am  facut teste si este OK.

Incearca te rog aceasta librarie.

TFT.rar

Incearca te rog aceasta librarie.

Nu merg .La compilare imi da erori.

[nico_2010]

Nu merg .La compilare imi da erori.

Ciudat, mie imi functioneaza libraria. Cum ai instalat-o?

inca o librarie (chiar daca este pentru 2.6 inch merge)

2-6 inch touch tft libraries.rar

[nico_2010]

Acum am testat aceasta librarie si functioneaza.

Programul de test functioneaza, de asemenea.

   Tot nu merge .Eroare in continuare. 

Acest cod imi compileaza:

 

 

 

// Touch screen library with X Y and Z (pressure) readings as well

// as oversampling to avoid 'bouncing'

// This demo code returns raw readings, public domain

 

#include <stdint.h>

#include "TouchScreen.h"

 

#define YP A2  // must be an analog pin, use "An" notation!

#define XM A3  // must be an analog pin, use "An" notation!

#define YM 8   // can be a digital pin

#define XP 9   // can be a digital pin

 

// For better pressure precision, we need to know the resistance

// between X+ and X- Use any multimeter to read it

// For the one we're using, its 300 ohms across the X plate

TouchScreen ts = TouchScreen(XP, YP, XM, YM, 300);

 

void setup(void) {

  Serial.begin(9600);

}

 

void loop(void) {

  // a point object holds x y and z coordinates

  Point p = ts.getPoint();

  // we have some minimum pressure we consider 'valid'

  // pressure of 0 means no pressing!

  if (p.z > ts.pressureThreshhold) {

     Serial.print("X = "); Serial.print(p.x);

     Serial.print("tY = "); Serial.print(p.y);

     Serial.print("tPressure = "); Serial.println(p.z);

  }

 

  delay(100);

}

 

 

si acesta dar  nu este pentru tft-ul care il detin:

 Arduino TFT Bitmap Logo example

 

 This example reads an image file from a micro-SD card

 and draws it on the screen, at random locations.

 

 In this sketch, the Arduino logo is read from a micro-SD card.

 There is a .bmp file included with this sketch.

 - open the sketch folder (Ctrl-K or Cmd-K)

 - copy the "arduino.bmp" file to a micro-SD

 - put the SD into the SD slot of the Arduino TFT module.

 

 This example code is in the public domain.

In mesaj am mentionat ca tftpaint nu functioneaza.

[nico_2010]

In atasament gasiti o alta versiune functionala (inclusiv partea de touchscreen)

In imagine Arduino in functiune cu programul tftpaint_azi.pde

Salut .Da intradevar  functioneaza .Ce am reusit sa testez sunt aici pe pagina:https://www.facebook.com/vonutan
