It would take one chip. It seems that most of you think that this is the simplest solution. In fact I think that too :). So I'm going to change the order of my "tries" and put this one as a first try. If I understand right, a general algorithm could be: 1 - Latch the STROBE line 2 - lock the sender (manipulating ACK and BUSY signals) 3 - read the data lines 4 - free STROBE line 5 - unlock sender What do you think? It seems right isn't it? []s <--- is this a world wide know icon? Rodrigo -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
