I am trying to get the BC127 to take an I2S input and output the sound onto my bluetooth speakers.
The I2S input that I am using is a simple 440Hz square wave with a sample rate of 8000Hz and 16 bit sampling and in Left_Justified_Mode. I am doing this using this arduino sample code and setup:
The two are connected: Arduino pin---------BC127 pin
I have the BC127 configuration as:
AUDIO_DIGITAL=0 8000 1 100200 ON
My understanding is that I want the AUDIO_DIGITAL set such that it has 16 bits/sample, set to slave, left justified and I don’t think the BCLK prescaling matters when in slave mode.
When I run the code and connect my Bluetooth headphones, I get no sound (not even the ‘pop’ when I run the PLAY command). What else might need to be set up on my AUDIO_DIGITAL?
