Here's some code that will convert a 16bit INT into individual characters


void calc_16(unsigned int value){
unsigned char temp1,temp2,temp3,temp4,temp5;
temp1=value%10;
value/=10;
temp2=value%10;
value /=10;
temp3=value%10;
value /=10;
temp4=value%10;
value /=10;
temp5=value%10;
k0=temp1 + 0x30;
k1=temp2 + 0x30;
k2=temp3 + 0x30;
k3=temp4 + 0x30;
k4=temp5 + 0x30;

}

Have a play , You can work out for yourself which is the MSB (K0 -K4 are external variable to the routine , and can be fed to an LCD etc..)
