Click library

  • Author : Luka Filipovic
  • Date : Sep 2021.
  • Type : SPI type

Software Support

We provide a library for the Buck16 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Buck16 Click driver.

Standard key functions :

  • buck16_cfg_setup Config Object Initialization function.

    void buck16_cfg_setup ( buck16_cfg_t *cfg );
  • buck16_init Initialization function.

    err_t buck16_init ( buck16_t *ctx, buck16_cfg_t *cfg );

Example key functions :

  • buck16_enable_output Enable/Disable voltage output.

    void buck16_enable_output ( buck16_t *ctx, uint8_t enable );
  • buck16_set_potentiometer Set potentiometer resistivity.

    err_t buck16_set_potentiometer ( buck16_t *ctx, uint16_t rwb );
  • buck16_set_output Set output voltage.

    err_t buck16_set_output ( buck16_t *ctx, uint16_t vout );

Example Description

This example showcases ability of the device to control voltage output of device. Output voltage can range from 800 to 5500 depending of VIN. By default it will go from 800 to 3300 VIN==VCC.

The demo application is composed of two sections :

Application Init

Initialization of communication modules (SPI, UART) and additional pin for enabling output and sets it to high.


void application_init ( void )
{
    log_cfg_t log_cfg;          /**< Logger config object. */
    buck16_cfg_t buck16_cfg;    /**< Click config object. */

    /** 
     * 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> Application Init <\r\n" );

    // Click initialization.
    buck16_cfg_setup( &buck16_cfg );
    BUCK16_MAP_MIKROBUS( buck16_cfg, MIKROBUS_1 );
    err_t init_flag  = buck16_init( &buck16, &buck16_cfg );
    if ( SPI_MASTER_ERROR == init_flag )
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    buck16_enable_output( &buck16, 1 );
    log_printf( &logger, "> Application Task <\r\n" );
}

Application Task

Sets voltage output first to 900mV then to 2500 mV. Then disables and enables output by toggling pin. In the end sets output value to 1500mV.


void application_task ( void )
{
    log_printf( &logger, " > Setting output to 0.9V\r\n" );
    buck16_set_output( &buck16, 900 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, " > Setting output to 2.5V\r\n" );
    buck16_set_output( &buck16, 2500 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, " > Disable output\r\n" );
    buck16_enable_output( &buck16, 0 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, " > Enable output\r\n" );
    buck16_enable_output( &buck16, 1 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, " > Setting output to 1.5V\r\n" );
    buck16_set_output( &buck16, 1500 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Buck16

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.
