UTFT help!!! myGLCD.print(sensorValue); error when compiling


i trying tft print simple analog inputs (raw values) 0-1023

i mimic commands code have running with  other 16x2 display <liquidcrystal.h library>

but <utft.h> library dont seem work same way .

is there different command 16x2lcd  <liquidcrystal.h> , when want tft display  to print analogread  ?

otherwise generic  test codes working properly





code: [select]
// utft_viewfont (c)2012 henning karlsen
// web: http://www.henningkarlsen.com/electronics
//
// program demo of included fonts.
//
// demo made modules screen resolution
// of 320x240 pixels.
//
// program requires utft library.
//

#include <utft.h>

// declare fonts using
extern uint8_t smallfont[];
extern uint8_t bigfont[];
extern uint8_t sevensegnumfont[];

// uncomment next line arduino 2009/uno
utft myglcd(qd_tft180b,11,10,9,12,8);   // remember change model parameter suit display module!

int sensorpin = a0;
int sensorvalue  ;


void setup()
{
 pinmode(sensorpin , input);
 myglcd.initlcd();

 myglcd.clrscr();
}

void loop()
{
 sensorvalue = analogread(sensorpin);
 
 myglcd.setcolor(255,255,255);
 myglcd.setbackcolor(0,0,0);
 myglcd.fillscr(0,0,0);

 myglcd.setfont(smallfont);
 myglcd.print("soil moisture:", left , 3);
 
 myglcd.print(sensorvalue ,right, 3);
 



 
 

 while(1) {};
}


error code:



code: [select]
utft_working.ino: in function 'void loop()':
utft_working.ino:42: warning: deprecated conversion string constant 'char*'
utft_working:44: error: invalid conversion 'int' 'const char*'
utft_working:44: error: initializing argument 1 of 'string::string(const char*)'

i suggest have @ difference between print, printnumi , printnumf functions.

the manual can found here http://henningkarlsen.com/electronics/library.php?id=51

cheers
