Hi,

This is not a query, it is just a clarification of operation.

When using "20x4 alphanumeric LCD" the configuration so that it is all in the left margin, is as follows:

D# ............... o = 0,0
D#............... o = 1,0
D#............... o = 2,4
D# ............... o = 3,4

Unlike the first two lines, in the last two lines you must place a 4-phase offset, if these last two lines will not appear on lines 1 and 2 at the end.

That way it works well.

I have not adapted the program part of the positioning conversion for a 20x4 display, since I still have not bought it.
Eventually the conversion will be automatic, as for all other listed displays.
