Hex to BCD conversion routine

[RG23]

Does anyone have an idea about Hex to BCD conversion routine using pic?

Please let me know

Thanks

[RG23]

Is there any subroutine available for converting hex to bcd?????

[DumboFixer]

What language are you using ?

Have you tried Google or Bing ?

Have you had a go yourself ?

[RG23]

i am using assembly language in pic

I tried google but didn't get any satisfying results

If you have any idea please let me know

Thanks

By hex do you mean a natural number stored in a register (or registers)? If so this should help. If you are not worried about memory, the unpacked BCD is easier to work with.

Unpacked BCD to 16 bit binary conversion by Nikolai Golovchenko

but using the above I would get binary result

i am getting the correct frequency but its in hex format

so i first need to convert hex to bcd

i have bcd to ascii subroutine to display on LCD

Thanks

[RG23]

At present when i divide 0x64 (decimal 100) by 0x21 (decimal 33)

I get 3.07 on LCD which is hex but i want to see 3.03 (decimal)

[RG23]

i have still not figured it out

any help would be appreciated

Thanks

Which unpacked bcd routine are you referring to?

[Markd77]

I meant one of the binary to unpacked BCD links.
Unpacked stores each BCD digit in a byte, but packed stores 2 BCD digits in each byte.
eg. 93 is stored as b'10010011' in packed but as b'00001001' and b'00000011' in unpacked.

I think we need to see your code to be more help.
