Sure, 2 different controllers that are both 'equiv to the 44780'. In other words, they'll mount the same, most likely initialize the same, and except for the different in the number of lines, operate the same.

I picked the 120x32 (I checked, and they publish this as the size, maybe it is a type) because it had a data sheet that at least looked like something I might be able to grasp (at least enough to get started! ha).
I just had a look at that datasheet. The company may have screwed up the datasheet all the way thru, or it really is a 120x32 LCD. If it is actually a 122x32, you'll notice 2 blank vertical lines in the middle of the LCD once you get it up and running, then you'll know it's a 122x32.
But it does use the SED1520 controller, the same thing as 'my' 122x32 GLCD, so the code should transplant right over.
