ST / Mbed 2 deprecated HelloWorld_CCA01M1

Simple test application for the STMicroelectronics X-NUCLEO-CCA01M1 Sound Terminal Expansion Board, built against mbed classic.

Dependencies:   X_NUCLEO_CCA01M1 ST_Events-old mbed

Fork of HelloWorld_CCA01M1_mbedOS by ST

Playing audio with the X-NUCLEO-CCA01M1 Expansion Board

This application provides a simple example of usage of the X-NUCLEO-CCA01M1 Sound Terminal Expansion Board, built against mbed classic.

It shows how to play a 2-channel stereo signal stored in an array of PCM samples directly on the speakers connected to the expansion board.

It also allows to stop/play the audio by pressing the user button on the Nucleo board.


Platform compatibility

  • This board can be currently used with a Nucleo-F401RE board only and has been tested with the default configuration provided by this example.
  • Please note that the main application makes use of the "events" library, which is not included into the "mbed" library.
  • The application built against mbed OS 5.x can be found here.
