Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the boostinv2 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 boostinv2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void boostinv2_cfg_setup ( boostinv2_cfg_t *cfg );

  • Initialization function.

    BOOSTONV2_RETVAL boostinv2_init ( boostinv2_t ctx, boostinv2_cfg_t cfg );

  • Click Default Configuration function.

    void boostinv2_default_cfg ( boostinv2_t *ctx );

Example key functions :

  • Functions for set positive output voltage.

    void boostinv2_set_positive_voltage ( boostinv2_t *ctx, uint16_t voltage );

  • Functions for set negative output voltage.

    void boostinv2_set_negative_voltage ( boostinv2_t *ctx, uint16_t voltage );

  • Generic transfer function.

    void boostinv2_generic_transfer ( boostinv2_t ctx, spi_master_transfer_data_t block );

Examples Description

First increse positiv voltage by 2V every 3 seconda, then decrese negative value for -2v every 3 seconds.

The demo application is composed of two sections :

Application Init

Initializes Driver init and enable chip

void application_init ( void )
{
    log_cfg_t log_cfg;
    boostinv2_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.

    boostinv2_cfg_setup( &cfg );
    BOOSTONV2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    boostinv2_init( &boostinv2, &cfg );

    boostinv2_enable( &boostinv2 ); 
} 

Application Task

Changes the positive and negative output voltage. Positive output voltage goes from 5V to 15V. Negative output voltage goes from -5V to -15V

void application_task ( void )
{
     // Positive output voltage 
     log_printf( &logger, "VOUT = 6V\r\n");
     boostinv2_set_positive_voltage( &boostinv2, BOOSTINV2_POS_VOUT_6V );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     log_printf( &logger, "VOUT = 8V\r\n");
     boostinv2_set_positive_voltage( &boostinv2, BOOSTINV2_POS_VOUT_8V );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     log_printf( &logger, "VOUT = 12V\r\n");
     boostinv2_set_positive_voltage( &boostinv2, BOOSTINV2_POS_VOUT_12V );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     log_printf( &logger, "VOUT = 14V\r\n");
     boostinv2_set_positive_voltage( &boostinv2, BOOSTINV2_POS_VOUT_14V );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     log_printf( &logger, "VOUT = 12V\r\n");
     boostinv2_set_positive_voltage( &boostinv2, BOOSTINV2_POS_VOUT_12V );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     log_printf( &logger, "VOUT = 8V\r\n");
     boostinv2_set_positive_voltage( &boostinv2, BOOSTINV2_POS_VOUT_8V );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );

     // Negative output voltage 

     log_printf( &logger, "VOUT = -5V\r\n");
     boostinv2_set_negative_voltage( &boostinv2, BOOSTINV2_NEG_VOUT_5V );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     log_printf( &logger, "VOUT = -7V\r\n");
     boostinv2_set_negative_voltage( &boostinv2, BOOSTINV2_NEG_VOUT_7V );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     log_printf( &logger, "VOUT = -13V\r\n");
     boostinv2_set_negative_voltage( &boostinv2, BOOSTINV2_NEG_VOUT_13V );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     Delay_ms ( 1000 );
     log_printf( &logger, "VOUT = -7V\r\n");
     boostinv2_set_negative_voltage( &boostinv2, BOOSTINV2_NEG_VOUT_7V );
     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.Boostinv2

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.
