Hi
Where do you find the connections to the FPGA? I mean how do you know what pins to connect to the module you just progammed some code for ? I use the Nios II embedded evaluation kit cyclone III edition, with the daughter board. On the board I want to connect a microphone, it has 4 wires. Where can I connect this ? I would like to have the Pin information Settings for the whole board. Just like Xilinx, in their guide for the boards the explain the buttons and then they write the pin connections. The same with the RS-232, lights, and all other components on the board. How does this work in quartus :confused: BR BenjaminLink Copied

There's a lot of documentation: Schematics, user manuals, FPGA pin lists. I got them from the Altera site, but I would expect they have been shipped with the board. A microsphone should be connected to the audio codec, it has a microphone jack. What are you missing particularly?

This page has everything you could ever need for your kit. Go to the bottom of the page for all the documentation.

Hi
Sorry I should have told you that it is a digital microphone, so I just need 4 digital connections on the board. I have found the following connections on the daughter board: http://nygaard1899.dk/Daughterboard.bmp What 4 lines can I use? And what is the pin connection that I have to setup in quartus on the FPGA(CyloneIII EP3C25F324C6NES)? The drawing is from lcd_multimedia_daughtercard.pdf BR Benjamin- Mark as New

What do you mean by "digital microphone"? A microphone with digital audio output? In this case you don't have to connect it to the audio codec, but directly to digital I/O of the board. Please clarify better.

Hi
Yes a microphone with digital audio output. Yes I just need to connect it to a digital I/O, but I would like to use the connections on the drawing but what is the pin connections in the FPGA that connects to these I/O? With the pin connections I mean in Quartus->Assignments->Pins BR Benjamin- Mark as New

Have a look at the excel file "CIII_SK_pinTable.xls" which you will find in the included documentation with your kit. You have to select one of the FPGA pins that are connecetd to the HSMC interface.

Sorry, four of the FPGA pins connected to the HSMC interface.

Hi
Thanks that helped a bit. I found the file. But I still can´t find any free connections. I have found this on the main board: Signal Name FPGA Pin Name Direction Type HSMC Pin HSMC_D0 H6 Bidirectional 2.5 V 41 HSMC_D1 D3 Bidirectional 2.5 V 42 HSMC_D2 M5 Bidirectional 2.5 V 43 HSMC_D3 L6 Bidirectional 2.5 V 44 But thay are alle connected to some chip on the daughter board? I just can´t find any free connections on the HSMC Expansion Connector. The best solution would be to find some free connections on the main board. BR Benjamin- Mark as New

The multimedia daughter board may or may not have unconnected HSMC signals (I think, it has some), but it obviously has no free connectors for additional digital signals. You could use the PS2 or SD/MMC connector if not needed otherwise.
