  • Type : GPIO type

Software Support

We provide a library for the AudioAmp 9 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.

Library Description

This library contains API for AudioAmp 9 Click driver.

Example Description

This library contains API for AudioAmp 9 Click driver.

The library initializes and defines the GPIO drivers.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs default configuration putting AudioAmp 9 Click

into Gain 1 mode with unmuted output.

void application_init ( void )
{
log_cfg_t log_cfg;
audioamp9_cfg_t audioamp9_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
audioamp9_cfg_setup( &audioamp9_cfg );
AUDIOAMP9_MAP_MIKROBUS( audioamp9_cfg, MIKROBUS_1 );
if ( DIGITAL_OUT_UNSUPPORTED_PIN == audioamp9_init( &audioamp9, &audioamp9_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
audioamp9_default_cfg ( &audioamp9 );
log_info( &logger, " Application Task " );
}
#define AUDIOAMP9_MAP_MIKROBUS(cfg, mikrobus)

Application Task

This example demonstrates the use of the AudioAmp 9 Click board by

changing the gain level every 5 seconds, then muting the output for 5 seconds.

void application_task ( void )
{
for ( uint8_t vol_lvl = AUDIOAMP9_GAIN_LEVEL1; vol_lvl <= AUDIOAMP9_GAIN_LEVEL4; vol_lvl++ )
{
audioamp9_set_gain_level( &audioamp9, vol_lvl );
log_printf( &logger, " Volume gain level %d \r\n ", vol_lvl );
Delay_ms( 5000 );
}
log_printf( &logger, " Sound is muted \r\n " );
audioamp9_mute_on( &audioamp9 );
Delay_ms( 5000 );
log_printf( &logger, " Sound is unmuted \r\n " );
audioamp9_mute_off( &audioamp9 );
}

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.
