Hi all, I had a handyboard and an expansion board, they do not work together. I had definitely unzipped the explib into the libs directory and overwrote the files it need. But a strange problem occurs, when the board is downloading files at expsenc.c and hb_lib.icb, it said "analog already defined", "digital already defined" and "raw_analog already defined". I had try that to use the handyboard only with its own files, it works pretty good. But when work with exp board and exp files, the problem occurs. I had brorrowed an exp board from my friend, the same problem occur. My question is do anyone know what had happened on my boards? It seems that there is no problem on the exp board, I think the problem is on handyboard, is there any components burnt?? And what can I do with the boards??? Thank you very much

It may be because you use the wrong lib_hb.c. There is one that works with the expansion board (one without digital(), analog() and raw_analog() defined, but the expsenc.c will define them so that the I/O port on the expansion board will work). It (...) (25 years ago, 23-Feb-00, to lugnet.robotics.handyboard)
