Hallo

What is the quickest way to get BCD to DEC or Ascii to be displayed on lcd?

There is a good article on Wikipedia on BCD

Not sure how well this will work:

Code: Select all

dec = (bcd >> 4) * 10 + (bcd & 15)

Hi Martin / John

I've tested the code after I did some reading and my onboard RTCC is running at last. Thanks for the help.

Hi Desdewit,
Glad it's working for you.
If the code that worked was different to what I posted, would you mind posting it please, to help others that may be faced with the same issue.
Or was it the code I posted you used?

Hi Martin

The code you posted worked but I will post a basic program for the onboard rtc over the weekend.
