Hi Everybody! i have a trouble: i am trying to use the audio codec of the board, but it has an analog stage before the codec (50ad) that eliminates DC (i see on the schematic "5402_DSK_schem.pdf"). If i need this DC, it would work if i short-circuit the capacitors. This also is present in the other sense (output). if i want to send out a signal with DC component, may i short-circuit the caps too? Thanks a lot |

turn off the DC filtering of the codec of DSK5402

I think it will work; except I think there is more than one cap on both input and output sides that you need to deal with. I believe that one of our engineers had to do a similar thing last year for a customer. Please let me know if it works for you. Jeff Brower DSP sw/hw engineer Signalogic |
