Mic Click

Mic 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 : MikroE Team
• Date : Dec 2019.
• Type : ADC type

Software Support

Example Description

This example showcases the initialization and configuration of the Click and logger modules and later on reads and displays data recorded by the mic.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Mic

Example Key Functions

• mic_cfg_setup Config Object Initialization function.

void mic_cfg_setup ( mic_cfg_t *cfg );

• mic_init Initialization function.

err_t mic_init ( mic_t *ctx, mic_cfg_t *cfg );

• mic_default_cfg Click Default Configuration function.

void mic_default_cfg ( mic_t *ctx );

• mic_generic_read This function read ADC data.

mic_data_t mic_generic_read ( mic_t *ctx );

Application Init

Initializes LOG communication, ADC and configures AN pin as input on MIKROBUS1.

void application_init ( void )
{
    log_cfg_t log_cfg;
    mic_cfg_t cfg;

    /** 
     * 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.

    mic_cfg_setup( &cfg );
    MIC_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    mic_init( &mic, &cfg );
}

Application Task

Reads 12 bit ADC data from AN pin and displays it using the logger module.

void application_task ( void )
{
    mic_data_t tmp;
    
    //  Task implementation.
    
    tmp = mic_generic_read ( &mic );
    
    log_printf( &logger, "** ADC value : [DEC]- %d, [HEX]- 0x%x \r\n", tmp, tmp );

    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.
