Click library

  • Author : Stefan Filipovic
  • Date : Mar 2022.
  • Type : I2C/SPI type

Software Support

We provide a library for the Smart Mic 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 Smart Mic Click driver.

Standard key functions :

  • smartmic_cfg_setup Config Object Initialization function.

    void smartmic_cfg_setup ( smartmic_cfg_t *cfg );
  • smartmic_init Initialization function.

    err_t smartmic_init ( smartmic_t *ctx, smartmic_cfg_t *cfg );
  • smartmic_default_cfg Click Default Configuration function.

    err_t smartmic_default_cfg ( smartmic_t *ctx );

Example key functions :

  • smartmic_wait_keyword This function waits for a keyword event and then reads it and returns the keyword ID number.

    err_t smartmic_wait_keyword ( smartmic_t *ctx );
  • smartmic_download_keyword This function downloads keyword models to the module.

    err_t smartmic_download_keyword ( smartmic_t *ctx, uint16_t *data_in, uint16_t len );
  • smartmic_voice_make This function performs voice make feature. It stops the route, then sets digital gain to 20db, sample rate to 16K, frame size to 16 ms, and finally it selects route 6 and configures algorithm parameters.

    err_t smartmic_voice_make ( smartmic_t *ctx );

Example Description

This example demonstrates the use of Smart Mic Click board by programming it with 4 different keywords, and then waiting for a keyword event, parsing it and displaying on the USB UART.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration which programs the device with system config, firmware, and 4 keywords ("Hello VoiceQ","Switch The Light","Next Song","Baidu Yixia") binaries.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    smartmic_cfg_t smartmic_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.
    smartmic_cfg_setup( &smartmic_cfg );
    SMARTMIC_MAP_MIKROBUS( smartmic_cfg, MIKROBUS_1 );
    if ( SMARTMIC_OK != smartmic_init( &smartmic, &smartmic_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    log_printf( &logger, " Configuring device... \r\n" );

    if ( SMARTMIC_OK != smartmic_default_cfg ( &smartmic ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Waits for a keyword event, parses it and displays on the USB UART an appropriate message for the detected keyword.

void application_task ( void )
{
    switch ( smartmic_wait_keyword ( &smartmic ) )
    {
        case SMARTMIC_OEM1_KWD_DETECTED:
        {
            log_printf ( &logger, " Hello VoiceQ keyword detected!\r\n" );
            break;
        }
        case SMARTMIC_OEM2_KWD_DETECTED:
        {
            log_printf ( &logger, " Switch The Light keyword detected!\r\n" );
            break;
        }
        case SMARTMIC_OEM3_KWD_DETECTED:
        {
            log_printf ( &logger, " Next Song keyword detected!\r\n" );
            break;
        }
        case SMARTMIC_OEM4_KWD_DETECTED:
        {
            log_printf ( &logger, " Baidu YiXia keyword detected!\r\n" );
            break;
        } 
    }
}

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.SmartMic

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.

MCP251863 Click is a compact add-on board representing a complete CAN solution used as a control node in a CAN network. This board features the MCP251863, IC representing a compact solution with a controller and a transceiver in one package, the MCP2518FD and ATA6563 from Microchip. The ATA6563, a low-level physical layer IC (PHY), provides a physical connection with the CAN bus itself, while the CAN controller MCP2518FD represents an interface between the MCU and the PHY. It features three operating modes with dedicated fail-safe features, remote wake-up via CAN, and ideally passive behavior when powered off on the CAN bus. This Click board™ is suitable for developing a wide range of automotive diagnostic applications, even on MCUs that don’t support CAN interface.
