Audio Xover Click is an analog active crossover solution for two-way loudspeakers. The primary purpose of the crossover circuit in a loudspeaker is to split an incoming audio signal into frequency bands that are passed to the speaker or “driver” best suited.
We provide a library for the AudioXover 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for AudioXover Click driver.
Config Object Initialization function.
void audioxover_cfg_setup ( audioxover_cfg_t *cfg );
Initialization function.
AUDIOXOVER_RETVAL audioxover_init ( audioxover_t ctx, audioxover_cfg_t cfg );
Device power on function.
void audioxover_power_on ( audioxover_t *ctx );
Device shut down function.
void audioxover_shut_down ( audioxover_t *ctx );
This function initializes the driver and makes an initial log.
The demo application is composed of two sections :
This function initializes and configures the Click and logger modules.
void application_init ( void )
{
log_cfg_t log_cfg;
audioxover_cfg_t cfg;
/**
* 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_info( &logger, "---- Application Init ----" );
// Click initialization.
audioxover_cfg_setup( &cfg );
AUDIOXOVER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
audioxover_init( &audioxover, &cfg );
}
This function enables and disables the Click board every 10 seconds, and logs an appropriate message on the USB UART.
void application_task ( void )
{
log_printf( &logger, " * Switch: ON *\r\n" );
audioxover_power_on ( &audioxover );

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
