Tool/software: Code Composer Studio
Hi,
I am a beginner using I2S protocol and i have some clarification ;
I use an I2S audio Microphone SPH0645LM4H that have 3 pins and i use them to establish connection using I2S with CC3220MODASF:
DOUT connected to pin64 SD0.
LRLC connected to pin63 WS.
BCLK connected to pin53 SCK.
I use the default params config of I2S and when i check those param i found that the first one is sampling freq = 1000, what does mean this value? The data Sheet of SPH0645LM4H indicate that " The Over Sampling Rate is fixed at 64 therefore the WS signal must be BCLK/64 and synchronized to the BCLK. Clock frequencies from 1.024Mhz to 4.096MHz are supported so sampling rates from 16KHz to 64KHz can be had by changing the clock" how can i translate this to params in the I2S configuration ?
I want to read continuously the audio signal from the SPH0645LM4H Microphone and i don't have an example that help me to extract the signal continuously.
Thanks.
Best regards.
