The steps are;

1) Define an SOPC system containing; NIOS II + PIO + LCD

2) Write code to access the PIO and LCD at the addresses defined by the SOPC system.

The values of the data you have to write to the LCD to first initialize it, and then create text on it, is described in the Optrex manual.

Dave
