Speaker Click is a compact add-on board that contains an audio power amplifier with a high-quality audio reproduction. This board features the MAX9717, a 1.4W mono bridge-tied load (BTL) architecture audio power amplifier from Maxim Integrated.
We provide a library for the Speaker Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on mikroE github account.
This library contains API for Speaker Click driver.
speaker_cfg_setup
Config Object Initialization function.
void speaker_cfg_setup ( speaker_cfg_t *cfg );
speaker_init
Initialization function.
SPEAKER_RETVAL speaker_init ( speaker_t *ctx, speaker_cfg_t *cfg );
speaker_default_cfg
Click Default Configuration function.
void speaker_default_cfg ( speaker_t *ctx );
speaker_shutdown
Speaker shutdown mode function.
err_t speaker_shutdown ( speaker_t *ctx );
speaker_normal_operation
Speaker normal operation mode function.
err_t speaker_normal_operation ( speaker_t *ctx );
speaker_enable_slave_amp
Speaker enables the slave amplifier function.
err_t speaker_enable_slave_amp ( speaker_t *ctx );
This library contains API for the Speaker Click driver. This application controls the operating modes of the Speaker Click board™.
The demo application is composed of two sections :
Initialization of GPIO module and log UART. After driver initialization, the application performs the default settings.
void application_init ( void ) {
log_cfg_t log_cfg; /**< Logger config object. */
speaker_cfg_t speaker_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_printf( &logger, "\r\n" );
log_info( &logger, " Application Init " );
// Click initialization.
speaker_cfg_setup( &speaker_cfg );
SPEAKER_MAP_MIKROBUS( speaker_cfg, MIKROBUS_1 );
if ( speaker_init( &speaker, &speaker_cfg ) == DIGITAL_OUT_UNSUPPORTED_PIN ) {
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
speaker_default_cfg ( &speaker );
log_info( &logger, " Application Task " );
Delay_ms ( 100 );
}
This is an example that shows the use of a Speaker Click board™. The task of the application consists of switching two modes of operation: normal and shutdown modes. Results are being sent to the Usart Terminal where you can track their changes.
void application_task ( void ) {
log_printf( &logger, "-------------------------\r\n" );
log_printf( &logger, " Normal Operation Mode \r\n" );
speaker_normal_operation( &speaker );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );

Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
log_printf( &logger, "-------------------------\r\n" );
log_printf( &logger, " Enter Shutdown Mode \r\n" );
speaker_shutdown( &speaker );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );

Delay_ms ( 1000 );
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on mikroE github account.

Additional notes and informations
Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all Mikroelektronika compilers.
