Hi.
Have this lineup, is that possible ?
Even with more LCD, if it's done same way.

That will work but you can use one less pin by connecting both LCD RS pins together to one PIC pin and using the E pins to select which LCD is used.

 

Since both the write and read operations are controlled by the E enable or clock line you just need to double up on this single line. The 5 other pins may be shared, or 6 pins if you choose to use the READ function.

If not using the READ function R/W should be grounded.

(WHY read a device when you know what you wrote there? READ also can be used to check the BUSY flag to know when the display is ready to accept more data.)
