I have just been able to convert any decimal from 0 - 99 to hex value You don't need to convert "decimal" to "hex" - you need to convert to BCD. "decimal" and "hex" are just different ways to display the same numeric value; What you actually need to do is to convert the storage format to BCD. make up 11 to 0x11 or 21 to 0x21. That sounds like a rather bizarre approach! Do you actually understand how BCD works? See: http://www.8052.com/forum/read/166907 And: http://www.8052.com/forum/read/166902 |
