Example application which combines the STMicroelectronics X-NUCLEO-CCA01M1 Sound Terminal Expansion Board and the X-NUCLEO-CCA02M1 MEMS Microphones Expansion Board to realize a simple stereo@32KHz Karaoke system. It is built against mbed OS.
Dependencies: X_NUCLEO_CCA02M1 X_NUCLEO_CCA01M1
Having fun with Karaoke
This application provides an example of usage of the X-NUCLEO-CCA01M1 Sound Terminal Expansion Board and the X-NUCLEO-CCA02M1 MEMS Microphones Expansion Board on top of a Nucleo-F401RE board to realize a simple stereo@32KHz Karaoke system: it records the audio through the microphones and plays it through the speakers on the fly. It is built against mbed OS.
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.
SW Configuration
Currently the only configuration supported is stereo@32KHz for both boards.
HW Configuration
To make the two audio boards work together, the X-NUCLEO-CCA01M1 Sound Terminal Expansion Board has to be configured to use the I2S2 peripheral of the Nucleo F401RE board: please refer to the X_NUCLEO_CCA01M1 page.
