ssd1289 is display'ing the clock & temperature wrong

Using Arduino Displays
1

Hy, this is my first post so, don't be hard on me. I'm a neewbie in arduino and i've make a clock/date & temperature "appliance" . The problem is on clock, the 01,02,03,04,05,06,07,08,09 minutes/seconds are displayed wrong (as you can see in the picture) and if the temperature is made of 1 digit ... well, you can see that too. Below is my code, and I don't know where i'm wrong ... Can you help me ?

#include <Wire.h>
#include <OneWire.h>
#include <DallasTemperature.h>
#include <UTFT.h>
#include "RTClib.h"
extern uint8_t SmallFont[];
extern uint8_t SixteenSegment[];
UTFT myGLCD(SSD1289, 38, 39, 40, 41);
RTC_DS1307 RTC;

#define ONE_WIRE_BUS 8

OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);

void setup(void) {
  myGLCD.InitLCD();
  myGLCD.clrScr();
  myGLCD.setColor(0, 255, 255);
  // Start up the library
  sensors.begin();
  Serial.begin(9600);
  Wire.begin();
  RTC.begin();
  if (! RTC.isrunning()) {
    Serial.println("RTC is NOT running!");
    // following line sets the RTC to the date & time this sketch was compiled
   // RTC.adjust(DateTime(__DATE__, __TIME__));
  }
}
void loop(void) {
  DateTime now = RTC.now();
  int temp = (sensors.getTempCByIndex(0));
  myGLCD.setFont(SmallFont);
  sensors.requestTemperatures(); // Send the command to get temperatures
  myGLCD.print("Digital Clock & Thermometer", CENTER, 10);
  myGLCD.setFont(SixteenSegment);
  myGLCD.printNumI(temp, CENTER, 50);
  myGLCD.print("'C", 240, 50);
  myGLCD.printNumI(now.year(), 200, 110);
  myGLCD.print("/", 170, 110);
  myGLCD.printNumI(now.month(), 120, 110);
  myGLCD.print("/", 75, 110);
  myGLCD.printNumI(now.day(), 15, 110);
  myGLCD.printNumI(now.hour(), 35, 170);
  myGLCD.print(":", 95, 170);
  myGLCD.printNumI(now.minute(), 130, 170);
  myGLCD.print(":", 190, 170);
  myGLCD.printNumI(now.second(), 220, 170);
}

Hello and welcome.

You have to overwrite the previous content of the screen, at least where you are drawing.

So, you could clear the whole screen, or you could use additional parameters of the printNumI function, as described in the UTFT manual.

For example:

myGLCD.printNumI(now.month(), 120, 110, 2, '0');

That's working, thank you very much !
