SLN-VIZNAS-IOT

[cloudersky]

I have some questions about SLN-VIZNAS-IOT. 

1.How should I demo SLN-VIZNAS-IOT PDM MEMS Microphones?

2.Does i.MX RT106F have the same microphone function as i.MX RT1060?

 i.MX RT106F use PDM MEMS Microphones but the SDK (SDK_2_8_1_SLN-VIZNAS-IOT) seems no audio output about PDM MEMS Microphones.

Please help me to solve these problem. Thanks

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1. How should I demo SLN-VIZNAS-IOT PDM MEMS Microphones?
-- For SLN-VIZNAS-IOT, the SDK library hasn't such a demo to test the Microphones on the board until now.
2. Does i.MX RT106F have the same microphone function as i.MX RT1060?
-- Yes.
Have a great day,
TIC

So  for SLN-VIZNAS-IOT, Will the SDK be updated about PDM MEMS Microphones in the future? 

The SDK_2_8_1_SLN-VIZNAS-IOT seems no PDM mic Init , so the SDK_2_8_1_SLN-VIZNAS-IOT can 

not use  PDM MEMS Microphones?

Please give me the  answer. Thanks

Hi，

Thanks for your reply.
1) So for SLN-VIZNAS-IOT, Will the SDK be updated about PDM MEMS Microphones in the future?
-- To be honest, I don't know and I guess they don't have the plan currently.
Hope it helps.
Have a great day,

So any suggestions about developing PDM MIC on the SLN-VIZNAS-IOT?   

Or I can refer to which SDK?

Hi，
Thanks for your reply.
1) So any suggestions about developing PDM MIC on the SLN-VIZNAS-IOT? Or I can refer to which SDK?
-- Please refer to the interrupt_record_playback demo in the SDK library for MIMXRT1060-EVK.

I study about interrupt_record_playback demo in the SDK library for MIMXRT1060-EVK. But it doesn't seem to use PDM mircophone. This demo uses both headphone mic and board main mic as input source.So it seems a little different ? So any suggestions about developing PDM MIC on the SLN-VIZNAS-IOT ? Or where can I start ? Thanks

Hi,
Thanks for your reply.
Please refer to the driver in the SDK library for SLN-LOCAL2-IOT which uses SPH0641LM4H too.
Have a great day,

Thank you for your reply.

I referred to your suggestion SDK library for SLN-LOCAL2-IOT.

I see that I can do this individually with SAI1, SAI2, and SAI3. But SAI1 has four TX RX.

For RT106S ,PDM MIC and audio amplifer use SAI1_RX_DATA0(MIC1) ,SAI1_RX_DATA1(MIC2),SAI2_RX_DATA1(MIC3),SAI3_RX_DATA1(AMP),

For 1060F ,  PDM MIC and audio amplifer use SAI1_RX_DATA0(MIC1) ,SAI1_RX_DATA1(AMP) ,SAI1_RX_DATA2(MIC2) .

If pdm mic and audio amplifer all ues SAI1RX ,Will there be a problem?

-- No, it's able to do it.
