Feeding delayed output back into input.

Howdy.

First off the board is pretty sweet. Currently using it with an arduino uno and looking to get the maple.

After futzing around with the variable delay sketch, i was curious how i could go about feeding the delayed out put back into the input. Any suggestions on resources to help me figure this out? I

Thanks in advance!

feedback is a great idea. there are 2 ways to do this. one is digitally. you just take your output variable and add it back in with your input variable before you do any math. the downside to this is that it takes up more processor resources. you can also do it in analog with a potentiometer. just connect the top of the pot to HP_L, or HP_R which are the headphone outputs. connect the bottom of the pot to HP_C, which is ground. then connect the wiper to IN_L or IN_R. the pot will then allow you to control the level of feedback. a 10k pot should be fine, a log taper would be best, but probably doesnt matter too much.

are you running this on an UNO or Dueminlaove? also, when did you download the library, and which one did you grab? i will double check that this all works.

i ran it on my arduino, and it worked, but i had to send a character first before the serial was recognized. try sending a character in the serial monitor, that should activate the serial.available(). are you calling serial.begin() before the codec initialization?
