Hi everybody
I'm Daniele from Italy and I'm happy to be here.
I'm tryng to dispaly a temperature by this display ( i've read everything )
but I've got a big problem
I see on dispaly e127 °C
and if i unplug +5 volts to ds18b20 it become 0 27 °C
this is the code that I wrote
Serial.println(temperature,DEC);
char buffer[4];
itoa(temperature,buffer,10);
ht1632_putchar(0 , 0, buffer[0]);
ht1632_putchar(6 , 0, buffer[1]);
ht1632_putchar(12 , 0, buffer[2]);
ht1632_putchar(18 , 0, buffer[3]);
ht1632_puttinychar(26 , 0, 'o');
ht1632_putchar(33 , 0, 'C');
delay(150);
any idea

thank you so much
Daniele
