Can I connect multiple I2S digital microphones (up to 8) to the OMAP L138 development kit?

Would this require additional HW?

Should I be looking at a different DSP development kit?

Thanks,

Mike

Mike,

McASP interface in the OMAPL138 device would support I2S protocol. But i am not sure you can connect upto 8 digital microphones to the OMAPL138 development board. I will check on this and update you.

Mike,

I did some research gone through some of the I2S microphone data manuals. From that i understand you can connect two microphones (stereo channels) on I2S bus. I will try to contact our internal I2S audio experts and check if i can get further information on your application.
