I checked the svn repository and you right ;-) SPBRGH was introduced in rev 5938. How could I do a such error?

No, thanks ;-) > Or you include the usart library sources into your project and avoid > linking against the io libraries, which allows you to step through the > library code as if it were your own ;-) This is a really good idea, why didn't I think of that before? I won't do it now as you point me the real "problem", but I retain the idea for future use. Thanks for your help! Regards, Alain PS: I spent many time to find how to use the pic16 usart library because the lack of documentation. As I'm now near to well understand how it works, I would like to write some words to document that library and make that documentation available in sdcc for future users, but how can I do? Add the doc in header files? A chapter in sdcc manual? Something else?
