Do you mean the decimal data is in ASCII character form?

as mentioned before, you need to be clear if the data is comming as ASCII or not..

if its ascii numbers, just substract 30...(0-9) - for letters... its somthing similar...

please take into acount that once you "translate" your Ascii to hex, its already in binary....
you can perform bitwise operations on hex numbers...like if they where binary... although you "see" 0xAB you in reality have "b10101011"

the complier does all the work for you...

int x = 10; // Dec
int x = 0x0A; // Hex
int x = b00001010; // bin

its all the same....
