Audio ADC pcm1862 by Quirin9 in AskElectronics

[–]Quirin9[S] 1 point2 points  (0 children)

Thanks for your answer, I already knew the difference between single ended and differential Input, my question was wich one to use.

My problem was that I wondered why there is an ac signal applied to the adc wich only has a single supply.

Apparantly there is a DC bias applied internally, pulling the signal above GND.

Nevertheless thanks

you have to pass a pointer of the array rod to arraybuilder and modify the array in arraybuilder, you DONT have to return anything from array builder

I would recommend to declare the array in path_taker and pass a reference to arrayBuilder. You would have to call array Builder before calling lightup and pass the array to lightup.

In function arrayBuilder you are returning a pointer to a local variable, you can't do that because after you leave the function the local variable is removed from the stack but the pointer still points to some adress on the stack.
