Debugging my wiring for a I2S serial data audio interface.
There is a pin labeled SCK. SCK is a synonym for BCLK , so that must be the BCLK pin. No , cant be that , there's a pin labled BCK . Oh wait maybe the pin labeled SCK actually means SYSCLK which is a synonym for MCLK.

Oh and the DIN pin is where the output data goes. I guess that bit sort of makes sense.

At now at least makes some audio output that indicates its working - I' m going to bed.

Audio reactive blinky! 😄 It took a while to figure out how to properly emulate I2S on the STM32 and set it up to continuously receive data.

I wrote exactly how to do it here: https://blog.soch.cc/emulate-i2s-stm32/

Looking at schematics and #firmware of #Teufel #MYND waterproof portable speaker.

Very cool to check out their #OpenHardware design, though not much to see.

Everything of note runs through the WB-2835P #Bluetooth / Audio Module. It even acts as USB-Soundcard and digitizes Line-In, then outputs #I2S to the amplifier chips.
