Click library

  • Author : Nenad Filipovic
  • Date : Aug 2021.
  • Type : I2C type

Software Support

We provide a library for the AudioAmp8 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 AudioAmp8 Click driver.

Standard key functions :

  • audioamp8_cfg_setup Config Object Initialization function.

    void audioamp8_cfg_setup ( audioamp8_cfg_t *cfg );
  • audioamp8_init Initialization function.

    err_t audioamp8_init ( audioamp8_t *ctx, audioamp8_cfg_t *cfg );
  • audioamp8_default_cfg Click Default Configuration function.

    err_t audioamp8_default_cfg ( audioamp8_t *ctx );

Example key functions :

  • audioamp8_set_config_power_mode AudioAmp 8 set power mode configuration function.

    err_t audioamp8_set_config_power_mode ( audioamp8_t *ctx, audioamp8_pwr_mon_cfg_t pwr_mode );
  • audioamp8_set_config_power_mode_profile AudioAmp 8 set power mode profile configuration function.

    err_t audioamp8_set_config_power_mode_profile ( audioamp8_t *ctx, audioamp8_pwr_mod_profile_cfg_t pm_profile );
  • audioamp8_channel_monitoring AudioAmp 8 monitors the status of the channel's function.

    err_t audioamp8_channel_monitoring ( audioamp8_t *ctx, uint8_t mon_ch, audioamp8_monitor_channel_t *ch_mon );

Example Description

This library contains API for AudioAmp 8 Click driver. The library initializes and defines the I2C bus drivers to write and read data from registers.

The demo application is composed of two sections :

Application Init

The initialization of I2C module, log UART, and additional pins. After the driver init and then executes a default configuration, the app performs a BTL signal configuration, configure power mode and configure power mode profile.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    audioamp8_cfg_t audioamp8_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_info( &logger, " Application Init " );

    // Click initialization.
    audioamp8_cfg_setup( &audioamp8_cfg );
    AUDIOAMP8_MAP_MIKROBUS( audioamp8_cfg, MIKROBUS_1 );
    err_t init_flag = audioamp8_init( &audioamp8, &audioamp8_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );
        for ( ; ; );
    }

    if ( AUDIOAMP8_ERROR == audioamp8_default_cfg ( &audioamp8 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    log_info( &logger, " Application Task " );
    log_printf( &logger, "-------------------------\r\n" );
    Delay_ms ( 1000 );
}

Application Task

This is an example that shows the use of a AudioAmp 8 Click board™. Display status monitoring for the channel 0 or channel 1. This task repeats every 2 seconds.


void application_task ( void ) 
{
    channel_status_monitoring( AUDIOAMP8_SET_MON_CH_0 );
    Delay_ms ( 1000 );
}

Additional Function

  • channel_status_monitoring The function displays the status monitoring channel.
    static void channel_status_monitoring ( uint8_t ch_sel );

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.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.AudioAmp8

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.
