hello
does anyone knows how it is possible to invert a char on a lcd (44780)?
means that all pixels of the 5*7 matrix for a sign will be inverted as in normal lcdout - so the black ones shine, and the hiddens are black
thanks a lot

As far as I know the 44780 does not allow for inverting.
You may be able to find a display type that is opposite of the normal (maybe called "Negative Transmissive").

It's only possible by using special characters memory, addressing pixel per pixel.
a lookup table will help ...
There have been threads here on how to draw smileys ... or special symbols.
