Kerri:
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,
