Octo sound card directly to fpga #5

Open gdragoi14 opened 6 years ago

Hi,

I want to connect the octo soundcard directly to an fpga board like a spartan7 via gpio/pmod (or other is there a better way?). I can obviously do this through an rpi connected to the fpga but i would prefer to do my audio processing without the extra hop. Is there any reason why this wouldn’t work?

Cheers, George

I think it can work. You will need to make sure you have the GPIO from here setup correctly : http://forum.audioinjector.net/viewtopic.php?f=9&t=1317 You will have to reference the machine driver setup for difference sampling rates. https://github.com/raspberrypi/linux/blob/rpi-4.14.y/sound/soc/bcm/audioinjector-octo-soundcard.c

I guess you will use i2c to control the codec ?
