How to access the audio jack input data on RT1050 kit

[shibani]

Hi,

I am a newbie to the RT1050 evk kit and was wondering if it would be possible to give an example of how to access the audio jack input and the other microphone input of the board? 

thank you.

Hello Shibani,

if you check out the SDK example (driver_examples->sai->sai_edma_record_playback or sai_interrupt_record_playback) you will be able to test both (correct me if I'm wrong).

When I tested it, I got the on-board mic on the right channel, and the audio jack microphone on the left channel.

Best regards,

T

Yes, right. but you should use headphone with 4 contact.

like this:

Headphone for phone should be OK.

Have a nice day!
