Configuring I2S/SAI on FRDM-KL46Z

ian_w — Wed, 13 Apr 2022 02:04:19 GMT

Hello,

I've attempted at configuring the I2S/SAI module on the FRDM-KL46Z board and I'm wondering what's the order of steps to correctly configure it. My goal is to transmit frames of single-toned frequencies from the FRDM-KL46Z in master mode to an MAX98357A audio amplifier. In the MCUExpresso IDE, I included the fsl_sai header/source files and tried setting it up on my own.

The MCUXpresso SDK API Reference Manual has a section on helper functions to set up I2S which I'll link below (as well as the reference manuals for both the board and the amplifier, if that helps).

Best regards,

Ian W

Hi @ian_w

Hope you are well, I would like to apologize for the delay on the answer. We are overloaded on the number of requests these days.

I would like to help you, but may you tell me more specifically what did you find on SDK reference manual about I2S that did not help you too much, so I can help you with that more personalizedly.

I will stay tuned to your answer, so please give more insight in order to support on you.

Thank you so much.
Best Regards.
Pablo Avalos.
