Build codal with the 'mems_mic_test()' function as the only thing in main() https://github.com/microbit-foundation/codal/blob/4ba584f78b61ce9789e548389a77ff542fe5a9f8/source/MicrophoneTest.cpp#L51
(or use the hex attached to this issue)
Copy the resulting hex to the micro:bit
Configure CoolTerm with the following settings:
Choose "Connection"-->"capture to text/binary file"-->"start recording"
Save to a file called "data.raw" Make some noise Choose "connection"-->"Capture to text/binary file"-->"stop"
In Audacity, choose File-->Import--> Raw Data
Select data.raw
Choose settings as follows
(Signed 8-bit, little endian, Mono, 11kHz)
That should be your audio
Right now (23rd Sept 2020) there's a DAL bug which means you get lopsided audio as follows
