Posted on May 19, 2015 at 08:06Hi. If I wish to use an audio codec that is NOT the CS43L22 on the Discovery board, is it necessary to use different GPIO pins than the ones that are already connected to the onboard codec? For example, GPIOD_pin4 is connected as the reset pin for the CS43L22, so do I need to use a different pin as reset if I wish to use an external codec?
