Click library

  • Author : Nenad Filipovic
  • Date : Apr 2021.
  • Type : GPIO type

Software Support

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.

Library Description

This library contains API for Speaker Click driver.

Standard key functions :

  • 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 );

Example key functions :

  • 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 );

Example Description

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 :

Application Init

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 );
}

Application Task

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 );
    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 );
    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.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Speaker

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.

Analog MUX 3 Click

0

Analog MUX 3 Click is a compact add-on board that switches one of the eight inputs to one output. This board features the ADG738, a CMOS analog matrix switch with a serially-controlled SPI interface from Analog Devices. In an active state, the ADG738 conducts equally well in both directions, making it suitable for multiplexing and demultiplexing applications. It can also be configured as a type of switch array where any, all, or none of eight switches may be closed any time. All channels exhibit ‘break-before-make switching action, preventing momentary shorting when switching channels. This Click board™ is suitable for a wide range of applications, from industrial and instrumentation to medical, consumer, communications, and automotive systems.

mikroSDK is the new software development kit used to bridge the gap between different development systems. Once developed, the code will work on any hardware platform which has mikroBUS and is supported by the mikroSDK. Easy to start, fast to learn, time saving, and open source - we designed mikroSDK with developers in mind.
