Click library

Software Support

We provide a library for the AudioAmp3 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.

Library Description

This library contains API for AudioAmp3 Click driver.

Standard key functions :

Example key functions :

Examples Description

This is an example which demonstrates the use of AudioAmp 3 click board, stereo audio amplifier.

The demo application is composed of two sections :

Application Init

Application Init performs Logger and Click initialization.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_printf( &logger, "--------------------------\r\n\n" );
log_printf( &logger, " Application Init\r\n" );
Delay_ms ( 100 );
// Click initialization.
AUDIOAMP3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
audioamp3_init( &audioamp3, &cfg );
log_printf( &logger, "--------------------------\r\n\n" );
log_printf( &logger, "--- AudioAmp 3 Click ---\r\n" );
log_printf( &logger, "--------------------------\r\n\n" );
Delay_ms ( 1000 );
audioamp3_power_up( &audioamp3 );
log_printf( &logger, " Power Up \r\n" );
log_printf( &logger, " ---------------------------\r\n\n" );
Delay_100ms();
log_printf( &logger, " Set channel 1 low-low state \r\n" );
log_printf( &logger, " ---------------------------\r\n\n" );
Delay_100ms();
log_printf( &logger, " Set channel 2 low-low state \r\n" );
log_printf( &logger, " ---------------------------\r\n\n" );
Delay_100ms();
log_printf( &logger, " Mute All Channels \r\n" );
log_printf( &logger, " ---------------------------\r\n\n" );
Delay_100ms();
log_printf( &logger, " Run Diagnostics \r\n" );
log_printf( &logger, " ---------------------------\r\n\n" );
Delay_100ms();
audioamp3_hw_reset( &audioamp3 );
log_printf( &logger, " Hardware Reset \r\n" );
log_printf( &logger, " ---------------------------\r\n\n" );
Delay_100ms();
log_printf( &logger, " Read Diagnostics \r\n" );
log_printf( &logger, " ---------------------------\r\n\n" );
Delay_100ms();
log_printf( &logger, "--------------------------\r\n\n" );
log_printf( &logger, " Initialization done \r\n" );
log_printf( &logger, "--------------------------\r\n\n" );
Delay_ms ( 1000 );
audioamp3_set_play_mode( &audioamp3 );
log_printf( &logger, " ---------------------------\r\n\n" );
log_printf( &logger, " Play \r\n" );
log_printf( &logger, " ---------------------------\r\n\n" );
Delay_100ms();
}

Application Task

This is an example which waits for valid user input and executes functions based on set of valid commands. Results are being sent to the UART Terminal where you can track their changes.

void application_task ( void )
{
{
log_printf( &logger, " - Volume Up - \r\n" );
Delay_ms( 2000 );
}
log_printf( &logger, " ---------------------------\r\n\n" );
{
log_printf( &logger, " - Volume Down - \r\n" );
Delay_ms( 2000 );
}
log_printf( &logger, " ---------------------------\r\n\n" );
}

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.
