Hello, I am migrating from LPCOpen DMIC examples to MCUXpresso SDK DMIC examples. I am using the LPCXpresso54114 Audio and Voice Kit with the MAO shield. Previously, I built and ran the LPCOpen 'periph_i2s_dmic' example. I take the CODEC output from the shield into an amplifier/headphones. This example worked just fine 'out-of-the-box'.
I am now trying the various SDK DMIC examples. There are two projects which are supposed to send data to the CODEC in a similar way: 1 - The 'DMIC_I2S_CODEC' project and 2 - the 'DMIC_I2S_DMA' project. So far I have been unable to get any audio output from either of these projects.
Also, in both projects there are two sections of code which are commented out; should these be uncommented ? Both sections ?
