KL26 USB microphone

[martindusek]

We have a device that is based on KL26 MCU and we came across an idea to implement USB microphone using that device. Is it practical to implement USB microphone using KL26? The device already runs Freescale USB stack (HID device) and for microphone it would have to run also USB audio class. Sampling frequency should be 22 kHz.

Hi Martin，

First of all, you can go for down the Kinetis SDK through the link as below.

And in the Kinetis SDK, it has contained various kind of USB demo which definitely includes the USB audio class.
