AXE133 Firmware with 20M2 & 2x24 display?

I notice the AXE133 firmware mentions 16 and 20 line calls - however I have 2x24 line display - will it work specifying 24 line? I have 20M2s and expect they are ok instead of 18M2 - thanks...

The 16x2 code will probably work fine, it allows for up to 64 characters on each line.

You might add a note in the datasheet, I would never have guessed.

This is a feature of the display driver itself, the clue is in the line 1 and line 2 character addresses, positions 128 and 192, hence allowing up to 64 characters on each line. This is also why line 3 is an extension of line 1 on the 20x4 displays, as the two 20 characters lines are often internally mapped as one long 40 character line.
