Click library

  • Author : Stefan Ilic
  • Date : May 2023.
  • Type : I2C type

Software Support

We provide a library for the Boost-INV 3 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 Boost-INV 3 Click driver.

Standard key functions :

  • boostinv3_cfg_setup Config Object Initialization function.

    void boostinv3_cfg_setup ( boostinv3_cfg_t *cfg );
  • boostinv3_init Initialization function.

    err_t boostinv3_init ( boostinv3_t *ctx, boostinv3_cfg_t *cfg );
  • boostinv3_default_cfg Click Default Configuration function.

    err_t boostinv3_default_cfg ( boostinv3_t *ctx );

Example key functions :

  • boostinv3_set_enp Boost-INV 3 set ENP pin state function.

    void boostinv3_set_enp ( boostinv3_t *ctx, uint8_t out_state );
  • boostinv3_set_pos_out Boost-INV 3 set positive output voltage function.

    err_t boostinv3_set_pos_out ( boostinv3_t *ctx, uint8_t out_val );
  • boostinv3_set_neg_out Boost-INV 3 set negative output voltage function.

    err_t boostinv3_set_neg_out ( boostinv3_t *ctx, uint8_t out_val );

Example Description

This library contains API for the Boost-INV 3 Click driver. This driver provides the functions to set the output voltage treshold.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART. After driver initialization, default settings enable the positive and negative output and sets the output voltage to 4 V.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    boostinv3_cfg_t boostinv3_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_info( &logger, " Application Init " );

    // Click initialization.
    boostinv3_cfg_setup( &boostinv3_cfg );
    BOOSTINV3_MAP_MIKROBUS( boostinv3_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == boostinv3_init( &boostinv3, &boostinv3_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    Delay_ms ( 100 );

    if ( BOOSTINV3_ERROR == boostinv3_default_cfg ( &boostinv3 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

This example demonstrates the use of the Boost-INV 3 Click board by changing

  • output voltage every 5 seconds starting from 4 V up to 6 V.
void application_task ( void ) 
{
    for ( uint8_t n_cnt = BOOSTINV3_OUT_VOLTAGE_4V; n_cnt <= BOOSTINV3_OUT_VOLTAGE_6V; n_cnt++ )
    {
        err_t error_flag = boostinv3_set_pos_out( &boostinv3, n_cnt );
        error_flag |= boostinv3_set_neg_out( &boostinv3, n_cnt );
        if ( BOOSTINV3_OK == error_flag )
        {
            log_printf( &logger, " Set positive and negative voltage to %.1f V \r\n", 
                        ( BOOSTINV3_MIN_VOL_LVL + n_cnt * BOOSTINV3_INCREMENT ) );
        }
        else
        {
            log_printf( &logger, " Error has occurred!!! \r\n" );
        }
        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.BoostINV3

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. UART terminal is available in all MikroElektronika compilers.
