Has anyone here tried doing I2C or SPI communication between two CSR8675 chips? Is this even possible? 8675 datasheet does not make it clear whether it supports I2C / SPI or not. At some sections it makes it sound like both are possible, at some it makes it sound like it only acts as a master. Does anyone have any experiences with this?
--EDIT:
What I need to do is something like this. I will have an analog mic attached to MIC A of CSR8675, I want to send the words of audio data received from this microphone via I2C/SPI to another CSR8675, collect them into a large buffer in the receiver CSR chip, perform some processing on it (for now, a simple multiplication of bit shift), send the digital version of this audio to the receiver CSR chip, process it further there and then play it out on the DAC of the receiver CSR chip. Is doing something like this feasible through I2C/SPI? I do not care about the delay between sound going into the microphone of the transmitting CSR chip and sound coming out of the speaker in the receiver CS chip, as long as all transmitted data is received.
Is I2S what I should be looking for? I have never done anything with I2S before. Does anyone have any pointers on where to start regarding this?
