Hi,I am wondering if there are any examples on how to communicate with the ADC Chip (WM8731) on the cyclone 2. I understand that the board uses the chip as a slave, but have no idea how to take samples from it. In the bigger picture, I am connecting my guitar into the mic input of the board and will do some signal processing from there. At the moment, I have no idea how to set up the board correctly. Any suggestions/help?
I have a Cyclone 2 EPC20F484C7. Not sure what is a DE/DE2-70 board. Sorry.I have gone through the examples in the CD-ROM but I am very confused with all the code as I am not familiar with Verilog. Also, must we use the NIOS processor to communicate with the ADC? Is it possible to build a block diagram which does the job and if so, where could I find such an example? Apologies, I am totally new to FPGAs and any help would be appreciated.
All Terasic Dev Kits with an audio codec come with Verilog demostration code. As far as I understand the code, you can use it without NIOS II. It has a state machine that controls the codec setup (sending several commands). I agree, that the demostration code is far from being instructive.
Hi Fantagiro_88,Do you have any solution to earlier topic that you wrote in 2009? If you could give a quick answer, it would be much appreciated. Thanks!:rolleyes:
