thanks! - that was the type of code i was looking for - works for now!:D
2  Topics / Robotics / Read Android sensor and send it to Arduino using Bluetooth? on: November 15, 2012, 05:57:10 am
hi there - i am looking in to making a project, where i would use my android phone to control(using androids gyroscope) 2 servos - so i need to set my bluetooth on arduino up to read that sensor value - but im pretty new at this - so anyone have an advice/tutorial about how to do it - i need help with:
1. Setting up the iteadstudio Bluetooth Shield V2.1 - how to read the value the android should send
2. find an app to android that will send its gyroscope over bluetooth.

so anyone know how to do any of this?

Try the UTFT library instead
well, now i will not give me errors - but the screen is still white?
i use a ITDB02 Arduino Shield v1.3
and a normal arduino UNO
and the code
Code:
// UTFT_Bitmap (C)2012 Henning Karlsen

//
// This program is a demo of the drawBitmap()-function.
//
// This demo was made to work on the 320x240 modules.
// Any other size displays may cause strange behaviour.
//
// This program requires the UTFT library.
//

#include <UTFT.h>
#include <avr/pgmspace.h>

// Declare which fonts we will be using
extern uint8_t SmallFont[];

// Uncomment the next line for Arduino 2009/Uno
UTFT myGLCD(ITDB32S,19,18,17,16);   // Remember to change the model parameter to suit your display module!

// Uncomment the next line for Arduino Mega
//UTFT myGLCD(ITDB32S,38,39,40,41);   // Remember to change the model parameter to suit your display module!

extern unsigned int info[0x400];
extern unsigned int icon[0x400];
extern unsigned int tux[0x400];

void setup()
{
  myGLCD.InitLCD();
  myGLCD.setFont(SmallFont);
}

void loop()
{
  myGLCD.fillScr(255, 255, 255);
  myGLCD.setColor(255, 255, 255);
  myGLCD.print(" *** A 10 by 7 grid of a 32x32 icon *** ", CENTER, 228);
  for (int x=0; x<10; x++)
    for (int y=0; y<7; y++)
      myGLCD.drawBitmap (x*32, y*32, 32, 32, info);

  delay(5000);
 
  myGLCD.fillScr(255, 255, 255);
  myGLCD.setColor(255, 255, 255);
  myGLCD.print("   Two different icons in scale 1 to 4  ", CENTER, 228);
  int x=0;
  for (int s=0; s<4; s++)
  {
    x+=(s*32);
    myGLCD.drawBitmap (x, 0, 32, 32, tux, s+1);
  }
  x=0;
  for (int s=4; s>0; s--)
  {
    myGLCD.drawBitmap (x, 224-(s*32), 32, 32, icon, s);
    x+=(s*32);
  }

  delay(5000);
}
but i still just get a white screen...

And your error messages?
invalid conversion from 'uint8_t*' to 'int'

6  Using Arduino / Displays / Tft 3.2 Touch will just not work -.- on: November 06, 2012, 01:55:13 pm
Hi there - im pretty new to arduino, and have played around with it for around 2 month - but today i recived my 3.2 tft touch screen ( TFT01-3.2 / ITDB02)
so i hooked it up to the shield i recived for it(so it works with an UNO instead of mega) - the only thing i else have done is installed library ITDB02_Graph16
and ITDB02_Touch - also i have maked sure that the code is set for the UNO with shield - but now when i tries to load an example code from the library it says " Invalid conversion from 'uint8_t*' to 'int'

so what do i do?

oh also i did remove a *
from the code the library ITDB02_Graph16.h        the * from the code #include "WProgram.h"

struct _current_font
{
   uint8_t* font;
   uint8_t x_size;
   uint8_t y_size;
   uint8_t offset;
   uint8_t numchars;
};

so what can it possible be i need to do?
