Honored ContributorHello 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. https://www.dropbox.com/s/q1yqr77xucjc0ld/hardware.jpg (https://www.dropbox.com/s/q1yqr77xucjc0ld/hardware.jpg) https://www.dropbox.com/s/660jtbpz57tyr2x/qsys.jpg (https://www.dropbox.com/s/660jtbpz57tyr2x/qsys.jpg) https://www.dropbox.com/s/iyfakq3nhugeyjt/system_h.jpg (https://www.dropbox.com/s/iyfakq3nhugeyjt/system_h.jpg) Thank you very much.
