I connected an atmel samr21 mcu to a tfa9882 amp board using an i2s bus configured to the gpio pins on the mcu. I am able to send data over to the tfa9882 but the sound is not coming of the speaker. It is a mono setup for 1 speaker. Im thinking that right now its a frequency problem.
Here on the Model-Based Design community we handle questions regarding our toolbox or other MATLAB/Simulink related questions. As I am not sure where is the place best suited for tfa9882 related questions, I would advice you to fill a request for technical support here (go to 'Go to Ticket'). In this way your request will be routed internally to the appropriate team that support this product.
