Honored ContributorNios II LCD Driver
Greetings. Quite simply my LCD doesn't "work" with Nios II. It has and does work with Nios I. From the simple "web server" default reference design where the display should show something...

I see that it is posted in the documents/errata.txt file. I should have read through this before beating my head against the wall! FYI, I searched the "Nios II Software Developer's Handbook", then checked the "Nios II Processor Reference Handbook" under Section II Peripheral Support. I see that the SDRAM Controller, DMA, PIO, Timer, JTAG UART, UART, SPI, EPCS, CFI, and SysID peripherals are nicely defined. Then again, since the LCD is nothing more than a PIO, it doesn't have to be included here... After checking through those two docs, I referred to the "Nios II Device Drivers" library in my IDE, and browsed to the altera_avalon_lcd_16207 directory. I briefly looked through the .c and .h files but didn't have much luck... It appeared to me that it "should" work. I am not really answering your question here so let's try this: In short, the best place to start looking should have been the readme.txt & errata.txt, but I figured I had something wrong and that it wasn't really errata at all. Having said that, I'm thankful for the Nios Forum because someone is bound to know the answer! Cheers, -Terry
