MIC 3 Click

MIC 3 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

  • Author : Stefan Ilic
  • Date : Sep 2021.
  • Type : GPIO type

Software Support

Example Description

This is an example that demonstrates the use of the MIC 3 Click board.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.MIC3

Example Key Functions

  • mic3_cfg_setup Config Object Initialization function.
void mic3_cfg_setup ( mic3_cfg_t *cfg );
  • mic3_init Initialization function.
err_t mic3_init ( mic3_t *ctx, mic3_cfg_t *cfg );
  • mic3_default_cfg Click Default Configuration function.
err_t mic3_default_cfg ( mic3_t *ctx );
  • mic3_shd_pin_set MIC 3 SHD pin setting function.
void mic3_shd_pin_set ( mic3_t *ctx, uint8_t state );

Application Init

Initialization of SHD to output and log module, maping GPIO for Mikrobus1, and seting SHD pin to HIGH state.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    mic3_cfg_t mic3_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.
    mic3_cfg_setup( &mic3_cfg );
    MIC3_MAP_MIKROBUS( mic3_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == mic3_init( &mic3, &mic3_cfg ) ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    mic3_default_cfg ( &mic3 );
    log_info( &logger, " Application Task " );
}

Application Task

Turning microphone on for the 5 seconds, then turning it off for 5 seconds.

void application_task ( void ) 
{
    log_printf( &logger, " - Microphone is turned on  - \r\n" );
    mic3_shd_pin_set( &mic3, MIC3_PIN_STATE_HIGH );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    
    log_printf( &logger, " - Microphone is turned off  - \r\n" );
    mic3_shd_pin_set( &mic3, MIC3_PIN_STATE_LOW );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

  • Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
  • UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
