MIC24055 click

MIC24055 click is the buck regulator that can deliver continuous output current up to 8A and can step down voltages from up to 19V which makes this click board easy to use with many power sources commonly available.

Click library

• Author : MikroE Team
• Date : jan 2020.
• Type : SPI type

Software Support

We provide a library for the Mic24055 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 Mic24055 Click driver.

Standard key functions :

• Config Object Initialization function.

  void mic24055_cfg_setup ( mic24055_cfg_t *cfg );

• Initialization function.

  MIC24055_RETVAL mic24055_init ( mic24055_t ctx, mic24055_cfg_t cfg );

Example key functions :

• Generic transfer function.

  void mic24055_generic_transfer ( mic24055_t ctx, spi_master_transfer_data_t block );

• Generic transfer function.

  void mic24055_dac_output ( mic24055_t *ctx, uint16_t value_dac );

• Set output voltage.

  void mic24055_set_vout ( mic24055_t *ctx, uint16_t voltage );

Examples Description

This application is the buck regulator.

The demo application is composed of two sections :

Application Init

Initializes click driver.

void application_init ( void )
{
    log_cfg_t log_cfg;
    mic24055_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.

    mic24055_cfg_setup( &cfg );
    MIC24055_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    mic24055_init( &mic24055, &cfg );
}

Application Task

Slowly alternates the click output between two values.

void application_task ( void )
{
    mic24055_set_vout( &mic24055, 1500 );
    log_printf( &logger, "VOUT set to 1500mV \r\n" );
    log_printf( &logger, "-------------------------- \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    mic24055_set_vout( &mic24055, 3300 );
    log_printf( &logger, "VOUT set to 3300mV \r\n" );
    log_printf( &logger, "-------------------------- \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    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.Mic24055

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.
