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¶
The X-NUCLEO-CCA01M1 Sound Terminal Expansion Board has to be powered with at least 5V DC. You can connect the VCC terminal to an external power supplier or directly to the +5V pin of the CN6 Arduino connector.
Platform compatibility¶
- This board can be currently used with a Nucleo-F401RE board only and has been tested with the default configuration provided by the HelloWorld_CCA01M1 example.
- The library is compatible both with mbed OS 5.x and mbed classic 2.x (to work with mbed classic, the main application has to import the "events" library, which is not included into the "mbed" library.).
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:
