Hi,
can you start to comment out parts of code until you get the minimal possible code that produces this error.
Then zip or rar your whole project folder (all the files) and send it to
If you can share your source that is

Thank You

Hi Marko,
I've found this:
You have to declare subroutines and function before 'implements'
Like:
And it works.
I don't know we have to do that
Anyway Thanks

Hi,
a few things had to be changed for this code to work:
Main code:
Module code:
The changes are as follows:
- PORTD.5 changed to RD5_bit (new approach to bits)
- Added lines
those lines were added because of the another bug reported but related to this code. http://www.mikroe.com/forum/viewtopic.php?t=19090
- and finally prototypes of the functions had to be declared before the implements statement so they could be visible from the main code.
Like we stated in topic above, problem with defines will be fixed for the official release.
