Click library

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

Software Support

We provide a library for the 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Mic Click driver.

Standard key functions :

  • Config Object Initialization function.

    void mic_cfg_setup ( mic_cfg_t *cfg );

  • Initialization function.

    MIC_RETVAL mic_init ( mic_t ctx, mic_cfg_t cfg );

  • Click Default Configuration function.

    void mic_default_cfg ( mic_t *ctx );

Example key functions :

  • This function read ADC data.

    mic_data_t mic_generic_read ( mic_t *ctx );

Examples 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.

The demo application is composed of two sections :

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 );
}  

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
