That method is as good as any but your digits are backwards. This will fix it.Your content value can be treated as either binary or decimal. If you think of it as decimal, a few lines of code can convert it into the equivalent digits. Then, display those digits. May not be efficient, but should work for your test.
Code:int counter=-1; int temp; byte digits[]={0,0,0,0}; // . . . counter++ temp=counter; for (int i=0; i<4; i ++) { digit[i] = temp % 10; temp = temp /10; }
temp=counter;
i = 4;
do{
i--;
digits[i] = temp % 10;
temp = temp /10;
}while(i);
