I don't think we've dealt with phantom-powered mics before. I'd guess you could use something like this, https://www.amazon.com/Neewer-1-Channel-Microphone-Condenser-Recording/dp/B0... - TB 03:52 AM PCB Development: RE: Development Kit Microphone Input Capture
- Hi Mike,
Thanks for replying. I will check that functionality as soon as I can and will let you know if there are any issues.
In the mean time do you have any advice on powering a headset/microphone that requires phantom power?

I can't say for sure, you may need to ask on the TI e2e for a definitive answer. But if I look at the AM572x and AM574x TRMs, both have the PRUSS registers at the same memory addresses.

- For clarification, the example i am using is Lab 2 from here: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/08_03_00_19/exports/docs/common/PRU-ICSS/PRU-Hands-on-Labs.html
- Hi,
I am using the MitySOM-AM57x development board, in conjunction with code developed from TI's PRU training series. I am wondering if the #include header files for the AM572x board (found in the example labs) are applicable for AM57...

- Scratch that, the input is connected to Line2 and is set up for Stereo input so the datasheet example I included above doesn't apply. I added a section to the wiki to modify the board for microphone in. Please let me know if you try it...

The 57x devkit audio input was hooked up as a Line Input. See the snippet from the datasheet.

According to the TLV320AIC3104 datasheet, to support a mic in, it should be hooked up like

I am working with the AM57x Development Kit with the MitySom-AM57x SOM.
I require microphone capture from the line input and have attempted adjusting amixer settings according to the Wiki and have had no luck in capturing microph...
