Hello everybody,
Forgive me if I am missing some basic points here but I am new to this so go easy on me.
I am trying to wire a dsPIC33F to accept stereo audio in via a 3.5mm jack and then immediately put it back out in stereo via another 3.5mm stereo jack.
I cannot figure out the wiring though. I've never had to wire audio jacks from scratch before. I'm confused by all the different 'voltages' involved (your positive/negative but also your references) and how they are wired.
Could anyone explain or perhaps link to a diagram of how to wire something like this? I'm also confused on the PIC pinout for your DAC. You got 3 pins for each L/R DAC (pos, neg, 'middle point') and, I think, positive/ground references for analog modules (??) AND positive/ground reference inputs for analog voltages (???... didn't know the two could be separate).
Any suggestions?
Thank you!!
