upside down LCD 2 x 16 lines!

Well. I got my connecting cable around the wrong way so my LCD is physically mounted 180degrees rotated. I am thinking there must be a software fix. Upside down character set? A search didn't show anything up. Is there an easy way to flip characters. I've checked viewing angles and they are fine! I can easily swap line 1 to 2 and reverse the order of the text it's just the font causing an issue!

I'm rather sure that it doesn't work.

It depends though, on quantities involved. The font is held in a ROM inside the chip, and many manufacturers will do custom units with different languages. If a large number of units are involved, it may be economic to get a custom unit made.
There are such units already on the market, in some sizes, and depending on the exact spec you may be able to find one. These are done for where the display is viewed through a mirror, or where it is necessary to install the display upside down. Units based on the Samsung KS0073 chip, offer the ability to do this.
However there is no 'simple' fix for this if your module doesn't use this controller.

Since you say you added a connecting cable, just rewire/replace that cable.
If that's not possible, perhaps a picture would show us other hardware possibilites.
To do it in software will be a challenge,but doable, depending on PIC you used(ROM space,speed,tasks,etc)

Have to disagree.
It is not 'doable in software'.
You have potentially 32 characters on the display. There are normally only 8 user definable characters available.....
