Boost-INV Click

Boost-INV Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Key Functions

• boostinv_cfg_setup Config Object Initialization function.

void boostinv_cfg_setup ( boostinv_cfg_t *cfg );

• boostinv_init Initialization function.

err_t boostinv_init ( boostinv_t *ctx, boostinv_cfg_t *cfg );

• boostinv_default_cfg Click Default Configuration function.

void boostinv_default_cfg ( boostinv_t *ctx );

• boostinv_enable Functions for enable chip.

void boostinv_enable ( boostinv_t *ctx );

• boostinv_set_positive_voltage Functions for set positive output voltage.

void boostinv_set_positive_voltage( boostinv_t *ctx, uint16_t voltage );

• boostinv_set_negative_voltage Functions for set negative output voltage.

void boostinv_set_negative_voltage( boostinv_t *ctx, int16_t voltage );

Application Init

Initializes I2C module and sets EN ( RST ) pin as output.

void application_init ( void )
{
    log_cfg_t log_cfg;
    boostinv_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.

    boostinv_cfg_setup( &cfg );
    BOOSTINV_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    boostinv_init( &boostinv, &cfg );
    
    boostinv_default_cfg ( &boostinv );

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
