Hello everybody,
i'm a student and a newbie at FPGA-programming. Right now i'm working with a DE0-Nano-board and i'm trying to write some characters on a 16x4 LCD-screen.
In QSYS i included the LCD-character-module and i tried to use some example source-code. I also found some posts in this forum but nothing really worked out. Maybe it's because the LCD-module in QSYS is especially for the "Optrex 16207". I found the "Optrex 16207 LCD Controller Core" in the "ug_embedded_id.pdf". But it didn't really helped me.
I'm using a TM164AAA module

I tried different example codes. Please find attached some pictures of my system and the source-code.
