Hello everybody,

i have a problem to get my LCD running at my DE0-Nano-board. The LCD module is a TM164AAA http://pdf.datasheetcatalog.net/datasheets2/36/361888_1.pdf (http://pdf.datasheetcatalog.net/datasheets2/36/361888_1.pdf)

I used Quartus and QSYS to add the LCD in the FPGA.

In nios 2 I tried different examplecodes but nothing worked. I would be very pleased if you could have a short look on my simple code/files.

I want to call the displayfunction in my mainfile. The files "display.h" , "display_1.h" and "display_2.h" are three different examplecodes.

Please find attached some screenshots of my system and the three display-files.

Thank you very much. I'm a newbie. Just want to see some characters on my LCD-screen...
