help me for IDE interface definition

[Altera_Forum]

hi guys, 

I'm about to design a project of mp3 player which based on IDE-Interface(using HDD for storage), we now have 20k200 development kit, please, where to find IDE-Interface definition documents, e.g. pin definition, controller chipset, or...  Where for these terms? I really need these documents, USB port, IDE... thx.

you can find the specifications you are looking for at www.t13.org 

 or use this links: http://www.t13.org/docs2004/d1532v1r4b%20a...ata-atapi-7.pdf (http://www.t13.org/docs2004/d1532v1r4b%20ata-atapi-7.pdf) http://www.t13.org/docs2004/d1532v2r4b%20a...ata-atapi-7.pdf (http://www.t13.org/docs2004/d1532v2r4b%20ata-atapi-7.pdf) http://www.t13.org/docs2004/d1532v3r4b%20a...ata-atapi-7.pdf (http://www.t13.org/docs2004/d1532v3r4b%20ata-atapi-7.pdf)  these are the documents to "ATA/ATAPI - 7 revision 4b" Vol. 1-3  hope this helps...  klaus

got new problem, when I finished the apex tutorial(nios i), there is a lcd test file named lcd_demo1.c, I try to build it but it says nr_timer_millisecond does not defined, if I slash that line, all things goes ok except the input function, if I use the apex standard_32 example project it goes ok, and I didn't find the difference between the two excaliber.c files, how is that going?

The MP3 example (I don't know if it was ever released as an example) was for Nios I on the Apex board. 

I'll see if I can find that design.

Faster, smaller and minus some of the baggage that worried me before (branch display slots). Unless you have good reason to use Nios I then I'd definately look into Nios II.  If you're a current Nios subscriber then you should have received your Nios II update, mine arrived a few weeks back, although I've been so busy I've not actually got round to playing with it anymore, so to answer your question, you get your licensed Nios II core from Altera!  Adrian

but Nios II seems not supported APEX(for that we only have apex kit).

Check your hardware configuration (SOPC builder)  Adrian
