Hi all, newbie here. I acquired a parallax serial LCD model #27977.
I thought this would be better as it has a one-wire interface instead of using a whole port.
I sent the baud rate to 2400.
I used the example program below to input something to it. With Button on I get a series of backslashes ”\\\\\\\”
When the button is off I get all kinds of gibberish like “\$2@@ $$.” The cursor jumps all around and it is never the same sequences on each power up.
OK I would really like to get this to print out data for diagnostic purposes.
Somebody help me out!!!! Regards, ED.

If Button On Then Temp = 0
If Button Off Then Temp = 100
