Hi,
I have some GLCD modules with inverted polarity CS1 and CS2 pins. How can I change the state of CS1 and CS2 pins in software?

If you use mE libraries, then unfortunately you can't invert them from software, you have to add a hardware inverters on both pins. Sorry.

SOLVED!!
using cs2 as cs1 and cs1 as cs2 with inverted polarity lcd modules it works but its too sensitive to noises.
