Hi guys, Anyone here ever do any work getting digital audio data into a Papilio? I'm working to create a waveform generator for amateur radio use using the Papilio One. The idea is to accept data from another computer in I/Q format and upconvert it in the FPGA to produce a signal in the 3 - 30 MHz range. Think a lower-frequency version of the GNU Radio USRP. I'm at the point where I need an interface to read in the I/Q data and am leaning toward creating a block that will impersonate the I2S interface of an audio codec. I'd be satisfied with a bandwidth of around 50 kHz (for now ) and I like how I2S explicitly identifies the right/left channels. However, I'm open to other ideas and thought I'd see if anyone here has done something similar before committing myself. Thanks for any suggestions, Joseph
