hd44780 does not work on PCF8574 based port extenders

Open mrmorphic opened this issue 12 years ago • 1 comments

as discussed on http://forum.arduino.cc/index.php?topic=158312.15 there are at least two variations of port extenders with different pin mappings to the LCD display itself.

This is delayed as I'm waiting for a new LCD display to test against the port extender.
