BUT what would the main pic actually be outputting on it's pin?
if that question makes sense, sorry never was any good at explaining things

Other question (sorry for so many)

Is there a chip such as the ds2408 that could be "piggybacked" onto the lcd module and convert it to 1-Wire® bus?
That would make it worth using the actual proper 1-Wire® bus especially if the lcdout command works the same as parallel lcd
Hi KarenHornby,
1 wire bus is a bit of a misnomer as they take at least 2 and usually 3, and that is all the serial backpack takes. Format your strings like LCDOUT as far as telling the lcd which line and which character to begin at, I usually use 9600 baud, so a typical serout statement;<br>
SEROUT YourPort,T9600,[254,1,"Karen's Project"]
SEROUT YourPort,T9600,[254,192,'This is FUN"]
<br>
YourPort = the pic pin you choose
254 of $FE, 192 or $C0, which is to say, same as in LCDOUT HEX or DEC. this backpack uses HSERIN so you must send data TRUE.
