Noise and Echo cancellation application with MIMXRT685

[AbhishekJani]

Spoiler

I want to build simple P.A. system application with single Mic and Speaker in which I need to remove echo and noise. Is it possible to do it with the MIMXRT685 in custom board?

What should I include in custom board?

Hi @AbhishekJani 

Do you test our NXP official MIMXRT685-EVK with the SDK code about the i2s:

SDK_2.9.0_EVK-MIMXRT685\boards\evkmimxrt685\driver_examples\i2s

Whether that echo and noise situation meet your demand or not?

Please test our official board and the code at first, if it meet your demand, then you can porting it to your customer board.

Thank you so much Kerry.

Actually I am currently figuring out the EVK. and Found that there are too many peripherals. I Need to make custom board which supports the P.A. system and for that I just need 1 mic, 1 speaker with amplifier and MIMXRT685. So to fulfil the application what should I put in to this custom board. 

I am new to NXP boards so I need help in selection of bare minimum ICs required to start with the custom board design

Thanks

Hi @AbhishekJani 

    Do you just need the RT do the  1 mic, 1 speaker? No other functions?

   The RT chip contains a lot of modules and pins:

So, if you just need one 1 mic, 1 speaker, I think you even can check the MCU which contains the SAI or I2S modules, the configure the RX and TX, associated with the external codec to realize it. The MCU can be kinetis or LPC.

Still need to check your detail requirement.

Wish it helps you!
