[SOLVED] conversion from hex to decimel

[wajid ali khan]

how to convert hex data from dptr to decimel in 8051(8 bit accumulator) ......

 

[shaiko]

I prefer to first convert it to binary and from binary to decimal.
Every Hex digit can be represented by 4 binary digits.
For example:
0xFF is binary - "1111 1111" which is 255 in decimal.
Another example-
0x12 is binary - "0001 0010" which is 18 in decimal.

The dptr is 16 bit and Acc is only 8 bit. You need to convert to 5 byte decimal ascii or 2.5 byte BCD format.

Which one do you prefer?

OK I think I misunderstood what you want. You want to convert what's in (DPTR) to decimal in Acc. But 8 bit hex would convert to 255 decimal max. So where to put the hundred digit?
