Hi,
After I sent an audio data to the PCM5100A via the I2S, there was no sound from the speaker.
Several key pin configurations are as follows：
I2S:BCK,LRCK,DIN
DEMP:Software reset FLT:Software reset XSMT:Software set OUTR: Connect to speaker
I using an oscilloscope to measure the pin, it is found that the BCK has about 2948Khz and the LRCK has about 92Khz waveform, the former is exactly 32 times that of the latter. The data input pin (DIN) also has a waveform, but the amplitude is only 100mv, is this normal? Data Output pin (OUTR) has no waveform.Does the sampling rate need to take into account the source properties?
What can I do to make the speaker sound? Thanks!
