Boost 8 Click

Boost 8 Click is a compact add-on board that steps up the voltage from its input (supply) to its output (load).

Click library

• Author : Stefan Ilic
• Date : Oct 2022.
• Type : GPIO type

Software Support

We provide a library for the Boost 8 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 8 Click driver.

Standard key functions :

• boost8_cfg_setup Config Object Initialization function.

  void boost8_cfg_setup ( boost8_cfg_t *cfg );

• boost8_init Initialization function.

  err_t boost8_init ( boost8_t *ctx, boost8_cfg_t *cfg );

• boost8_default_cfg Click Default Configuration function.

  void boost8_default_cfg ( boost8_t *ctx );

Example key functions :

• boost8_enable_positive_voltage Enable positive voltage output function.

  void boost8_enable_positive_voltage( boost8_t *ctx );

• boost8_disable_positive_voltage Disable positive voltage output function.

  void boost8_disable_positive_voltage( boost8_t *ctx );

• boost8_enable_negative_voltage Enable negative voltage output function.

  void boost8_enable_negative_voltage( boost8_t *ctx );

Example Description

This is an example that demonstrates the use of the Boost 8 Click board.

The demo application is composed of two sections :

Application Init

Initializes EN+ and EN- pins, UART log, and performs default configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    boost8_cfg_t boost8_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.
    boost8_cfg_setup( &boost8_cfg );
    BOOST8_MAP_MIKROBUS( boost8_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == boost8_init( &boost8, &boost8_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    boost8_default_cfg ( &boost8 );

    log_info( &logger, " Application Task " );
    boost8_list_of_commands();
}

Application Task

Waits for user input in order to determine what output should be enabled.

void application_task ( void ) 
{
    char inx;

    // Waiting for the user input and performing actions based on a selected command.
    if ( log_read( &logger, &inx, 1 ) != BOOST8_ERROR )
    {
        switch(inx)
        {
            case '1' :
            {
                log_printf( &logger, "Turning on positive output \r\n" );
                boost8_enable_positive_voltage( &boost8 );
                break;
            }
            case '2' :
            {
                log_printf( &logger, "Turning off positive output \r\n" );
                boost8_disable_positive_voltage( &boost8 );
                break;
            }
            case '3' :
            {
                log_printf( &logger, "Turning on negative output \r\n" );
                boost8_enable_negative_voltage( &boost8 );
                break;
            }
            case '4':
            {
                log_printf( &logger, "Turning off negative output \r\n" );
                boost8_disable_negative_voltage( &boost8 );
                break;
            }
            case '5' :
            {
                log_printf( &logger, "Turning on both outputs \r\n" );
                boost8_enable_both_outputs( &boost8 );
                break;
            }
            case '6' :
            {
                log_printf( &logger, "Turning off both outputs \r\n" );
                boost8_disable_both_outputs( &boost8 );
                break;
            }
            default:
            {
                log_printf( &logger, "> Invalid command \r\n" );
                boost8_list_of_commands();
                break;
            }
        }
    }

}

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.Boost8

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.
