Honored ContributorI noticed the audio fifo for the DAC; anyway, it seems that the examples configures the codec in slave mode, so the clocks are provided by the fpga.
I'd like to try to use the master mode before "copy" their project. I know there are sram and sdram, but I don't have a controller (except the one in qsys) and I don't want to waste time trying to make one from scratch by myself.. so it seems that the flash controller in universitiy program is simpler to use. Any hint would be VERY appreciated! Question not strictly related: as I drive unused pins to tristate with low resistance, red leds are powered up but all seems to work fine (except for gpio, "obvoiously"..). If I set them as output driving ground, direct connections between adc and dac don't work.. and many led red turn on(not hex display, I know they are active low) even if they are not declared into the schematic. Are there any raccomandations about driving unused pins?
