Example for FSMC or driving a LCD

> I would like to see an example about how to drive a LCD with F10X or F20X.

What LCD?

> Like bit banking RW/WR and handling data.

Do you mean

control signals? Then why do you mention FSMC?

What did you see? What other boards? Why wouldn't that help with other boards?

ST's EVAL series boards have FSMC attached LCD controllers.

Dozens of Olimex and Keil boards have 16x2 LCD displays with bit-banged control.

Read the Data Manuals for any given display, and look to how to emulate the data and control signals via GPIO pins, and pulling signals up and down as prescribed. I think you're creating all kinds of complications in your head that really don't exist. Examples exist for all manner of displays and processors, and it's all reasonably portable.

What you're not going to be able to do is generate video signals for dumb panels.
