Sound Terminal Library

Library to handle the X-NUCLEO-CCA01M1 Sound Terminal Expansion Board based on the STA350BW Sound Terminal device. A single board allows the output of a standard 2-channel stereo signal, while two boards stacked up realize a 4-channel audio system.

Power supply

This board has to be powerd with a 12V DC power supplier.

Platform compatibility

  • This board can be currently used with a Nucleo F401RE board and has been tested with the default configuration provided by the HelloWorld_CCA01M1 example.
  • At the moment the library is only compatible with mbedOS 5.

I2S Peripheral Usage

This board makes use of an I2S peripheral available on Nucleo boards, and when stacked up two times on the same Nucleo board each expansion board have to be configured to use a different I2S peripheral.

By default it comes with solder bridges configured to use the I2S1 peripheral, as depicted here below:

And can be set to use the I2S2 peripheral by configuring the solder bridges this way:
