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
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.
