In the process of working on a new Driver Tutorial for the ESPBasic Series I am looking today to implement some Decimal-to-BCD and BCD-to-Decimal subroutines.
What I have done so far:
1. BCD-to-Decimal subroutine:
[DEC] hv = val >> 4 hl = val and 15 val = hv*10 + hl wait
2. Decimal-to-BCD subroutine:
[BCD] d = int( val / 10 ) d1 = d * 10 d2 = val - d1 val = d*16 + d2 wait
If you have any other idea please feel free to share it, looking forward to see smarter solutions that that. I'm sure they are!
