MP Posted August 24, 2004 Report Share Posted August 24, 2004 Why even bother with the other chip? It is only saving you one port pin on the 2313. You could code these lines as well and save the cost of a chip and save board space. You are just sending ones and zeros to the port pins. Of course, if you use more than one array, you will be short a few pins. In that case, there is the AT90S8515 with 4 ports (32 port pins).MP Quote Link to comment Share on other sites More sharing options...
