display variables??? please help

[automotive78]

display : seeedstudio.com/wiki/2.8’’_TFT_Touch_Shield
board : arduino mega

We use the seeed shield tft but we need to display variables. Can anyone give us a hint how we can display by example the valua of a analog-pin value?

example: Tft.draw…??? variables?? ,170,320,2,BLUE);

Hi,
you can try to use the code like below :

  char s[20];
  int value ;
  value = analogRead(sensorPin);
  sprintf(s,"%d",value);
  Tft.drawString(s,0,160,1,CYAN);

#include <stdint.h>
#include <TouchScreen.h>
#include <TFT.h>
#ifdef MEGA
#define YP A2
#define XM A1
#define YM 54
#define XP 57
#endif
void setup()
{

Tft.init();
}

void loop()
{

char s[20];
int value ;
value = analogRead(A0);
sprintf(s,"%d",value);
Tft.drawString(s,0,160,3,CYAN);
delay(1000);
}

deray hi print it over what can i do to return or clear? please

Hi ,
Sorry that our engineer didn’t write the clear function ,we will add it later . Before , you can use the initialize function first.
