mov a,#06h
Mov b,#03h The numerical value #06h is not the same as the character value '6', is it? Generally, characters are transmitted using ASCII code: The ASCII code for a character '0' is 0x30; The ASCII code for a character '1' is 0x31; The ASCII code for a character '1' is 0x32; : The ASCII code for a character '8' is 0x38; The ASCII code for a character '9' is 0x39; You should be able to spot a pattern there that would make it easy to conver the ASCII codes for characters '0' to '9' into their corresponding numerical values... Here is a full chart of all the ASCII code values: http://www.asciichart.com/ascii_hexadecimal.html You should be able to work out a similar pattern for converting the ASCII codes for characters 'A' to 'F' into their corresponding numerical values... And another for characters 'a' to 'f'... See also: http://www.8052.com/forum/read.phtml?id=139235 |
