joesugar Posted November 11, 2015 Report Share Posted November 11, 2015 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 Quote Link to comment Share on other sites More sharing options...
