  1. Hello. If we use microphone line-in to input voice to pmod i2s2 (with given mclk 22.579MHz , sclk 2.822 MHz and lrck 44kHz) and pass-thru to pmod line out to headphone. Is it strong enough (our voice) to enable pass thru or loopback ? Tried both but no output from speaker ? i2s2.pdf

  3. Hello Jon, Using Trenz TE0630 Fpga module with carrier board (FPGA Module with Spartan-6 LX150). Can we just have simple test just for Pmod i2s2 module alone (set freq for LRCK and sclk , then monitor with oscilloscope) ? And what the difference if pmod use as master or slave ? Lastly could we do simple test (attachment pdf. Set mode as master . Then provide MCLK (LineIn) , connect A/D LRCK n SCLK to D/A LRCK n SCLK). Sinewave input to line-in input and monitor line-out output with oscilloscope ? Regards. testpmodi2s2.pdf
  4. Hello. Would like to use notebook audio in/out (mic/headphones or speaker) to test Pmod i2s2 loop back test ? Is there any such example to pump notebook audio out to pmod i2s2 linein and loopback 12-pin pmod connector loop-back , then pmod i2s2 lineout to notebook audio in or mic input ? Some sort of simple loopback test ? Regards.
  5. Hello to whom it may concern. Would like to know possible to use xilinx chipscope with Arty Board Artix-7 FPGA Development Board for debug logic signal ? If so how is it connected ? Or use existing arty board USB-JTAG Programming circuitry and use with chipscope tools ? Would like to port openrisc to Arty Board Artix-7 FPGA Development Board ? Any resource on it ? Thx and Regards.
