I2S master: Raspberry Pi 4 configured as detailed in https://github.com/AkiyukiOkayasu/RaspberryPi_I2S_Master/blob/master/i2smaster.dts Using Python script created audio stream for the captured audio file and executed stream write function as detailed below,
form_1 = pyaudio.paInt8 #8 bit resolution
samp_rate = 44100 # 44.1KHz
chans = 1
dev_index = 0
chunk = 4096
stream = audio.open(format = form_1,rate = samp_rate,channels = chans, \
input_device_index = dev_index,output = True, \
frames_per_buffer=chunk)
stream.write(frames)
Output signal from Raspberry Pi as observed on logic analyser: SCK=3MHz, WS=44.1KHz and data format=TDM stereo output
I2S slave: MCU configured as slave device (Expecting I2S format mono output with WS=187KHz). Received events on I2S slave callback, but no data received on the MCU.
Is there a way to output I2S format mono output with WS=187KHz from Raspberry Pi for the synchronization with MCU?
