Post by thread:[PIC]: Source code,

Well, it's been a year since I developed it and I haven't gotten any closer to setting things up so I can sell them (or any of the other devices I'd like to market), so here it is: http://www.ubasics.com/spic/ It uses a 16c54, is full-duplex (4800bps @4MHz), and can either be controlled with two simple commands, or act as a serial -- > parallel or parallel --> serial device. Some uses might include: Adding ports to smaller designs Sending 8 bits of data over a 2 wire connection (use two. At the fastest the outputs would be updated 2400 times per second) Hooking it up to a computer and have 8 bits of input/output for a serial port Controlling an LCD Multiplexing data streams (you can use a single device at 24kbps to reliably encode 8 2400bps streams into one stream, decoding could be done in software or using another of these) You could use 9 on each end of a 2 wire link to send 256 digital signals from one place to another, each signal being updated 240 times per second. (ok, this is a pretty expensive approach to solve a simple problem, but it would be fun...) I appreciate any comments. I'm afraid I cannot provide support for this. I've gone through it line by line with a fine-tooth comb and believe I have everything 'perfect', but I could easily be wrong. -Adam -- http://www.piclist.com hint: To leave the PICList spam_OUTpiclist-unsubscribe-requestTakeThisOuTmitvma.mit.edu
