Click library

• Author : MikroE Team
• Date : Jan 2020.
• Type : I2C type

Software Support

We provide a library for the Mic24045 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 Mic24045 Click driver.

Standard key functions :

• Config Object Initialization function.

  void mic24045_cfg_setup ( mic24045_cfg_t *cfg );

• Initialization function.

  MIC24045_RETVAL mic24045_init ( mic24045_t ctx, mic24045_cfg_t cfg );

• Enable voltage output.

  void mic24045_enable( mic24045_t *ctx );

Example key functions :

• Get voltage.

  float mic24045_get_vout ( mic24045_t *ctx );

• Set voltage decimal.

  void mic24045_set_vout_decimal ( mic24045_t *ctx, uint8_t dec );

• Get status function.

  uint8_t mic24045_get_status ( mic24045_t *ctx );

Examples Description

This example demonstrates the use of MIC24045 click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and enables the voltage output.

void application_init ( void )
{
    log_cfg_t log_cfg;
    mic24045_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.

    mic24045_cfg_setup( &cfg );
    MIC24045_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    mic24045_init( &mic24045, &cfg );

    mic24045_enable( &mic24045 );
    log_printf( &logger, " Output enabled!\r\n" );
    Delay_ms ( 100 );
}

Application Task

Changes the voltage output every 2 seconds and displays the current set value on the USB UART.

void application_task ( void )
{
    for ( uint16_t cnt = MIC24045_MIN_VOUT_DEC; cnt <= MIC24045_MAX_VOUT_DEC; cnt += 15 )
    {
        mic24045_set_vout_decimal( &mic24045, cnt );
        Delay_ms ( 500 );
        current_voltage = mic24045_get_vout( &mic24045 );

        log_printf( &logger, " VOUT:    ~%.3f V\r\n", current_voltage );
        log_printf( &logger, "------------------\r\n" );
        Delay_ms ( 1000 );
        Delay_ms ( 500 );
    }
}

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.Mic24045

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.
