Hi,
If I wanted to use a 4x4 keypad to set a frequency of output in the propeller and be able to read said frequency on a LCD display would I replace "VGA" in 4x4 keypad demo with Full Duplex Serial?
thanks,
Rich

    Assuming your LCD is a serial one, yes, you'd replace the VGA text driver with something like FullDuplexSerial. You don't usually need the buffering for output, so you could also use Simple_Serial for the LCD. There are several other versions of both for LCD displays and other debug or "console" output. Any one of those would work.
