Hello Gariyak,

Writing characters to the LCD goes far easier when you use the Nios II processor, because than you can communicate on a higher level.

When using the Nios II/e and 32kB On-chip memory the HAL (Hardware Abstraction Layer) enables you to use the alt_printf() function in an C-program to send characters to the display.

Through a PIO interface you can communicate between the state machine and the Nios II to determine when the next line of characters is being send to the LCD.
