Binary to BCD conversion

[towlerg]

Thanks for your reply. I am a little confused though, does this convert to ASCII rather than BCD?

I think I misunderstood the question, I thought BCD was a way of expressing a binary value as ASCII characters. So for example a byte would become two ASCII chars, a word 4 ASCII chars etc.

John, If you limit the accumulated value to say 5 digits as in a word (65535 max) then you can use it without LONG's. I use this method to display MPH with 3 decimal places on a terminal thru a serial port by adding:

TX_BYTES(TX_OUTPUT) = $30 + VALUE DIG JUNK 'Turn decimal value into ASCII

Dave,

Interesting approach, seems like I got too bogged down in shifting and adding multiple times rather than using the more obvious arithmetic capabilities of PICBASIC.

George,

Thanks for the hint on conversion to ASCII, I'm sure it will come in useful at some stage.
For info, BCD represents the decimal digits 0-9 using a nibble of data. With BCD only the states 0-9 are valid. 0xA to 0xF are forbidden. Its used for seven segment displays, real time clock modules, etc.
