Click library

• Author : Mihajlo Djordjevic
• Date : Dec 2019.
• Type : GPIO type

Software Support

We provide a library for the Mic23099 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 Mic23099 Click driver.

Standard key functions :

• Config Object Initialization function.

  void mic23099_cfg_setup ( mic23099_cfg_t *cfg );

• Initialization function.

  MIC23099_RETVAL mic23099_init ( mic23099_t ctx, mic23099_cfg_t cfg );

• Click Default Configuration function.

  void mic23099_default_cfg ( mic23099_t *ctx );

Example key functions :

• This function executes default configuration for MIC23099 click.

  void mic23099_default_cfg ( mic23099_t *ctx );

• This function checks the state of Power Good output pin.

  uint8_t mic23099_check_power_good ( mic23099_t *ctx );

Examples Description

This example shows usage of MIC23099 Click as step-down/step-up voltage regulator.

The demo application is composed of two sections :

Application Init

Application Init performs Logger and Click initialization.

void application_init ( void )
{
    log_cfg_t log_cfg;
    mic23099_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_printf( &logger, "--------------------------\r\n" );
    log_printf( &logger, "     Application  Init\r\n" );
    Delay_ms ( 1000 );

    //  Click initialization.

    mic23099_cfg_setup( &cfg );
    MIC23099_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    mic23099_init( &mic23099, &cfg );

    log_printf( &logger, "--------------------------\r\n" );
    log_printf( &logger, " ---- MIC23099 Click ---- \r\n" );
    log_printf( &logger, "--------------------------\r\n" );
    Delay_ms ( 1000 );

    mic23099_default_cfg( &mic23099 );
    Delay_ms ( 1000 );

    log_printf( &logger, " -- Initialization done --\r\n" );
    log_printf( &logger, "--------------------------\r\n" );
    Delay_ms ( 1000 );
}

Application Task

This example demonstrates the use of MIC23099 Click board by checking the state of power good pin and sends note via UART Terminal if the state is low.

void application_task ( void )
{
    uint8_t new_stat = 0;
    uint8_t old_stat = 1;

    new_stat = mic23099_check_power_good( &mic23099 );

    if ( new_stat == 1 && old_stat == 0 )
    {
        old_stat = 1;
    }

    if ( new_stat == 0 && old_stat == 1 )
    {
        log_printf( &logger, " Change  battery  and  reset. \r\n" );
        log_printf( &logger, "------------------------------\r\n" );
        old_stat = 0;
    }
}  

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.Mic23099

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.
