H-Bridge 9 Click

H-Bridge 9 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 Description

This example demonstrates the use of H-Bridge 9 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.HBridge9

Example Key Functions

• hbridge9_cfg_setup Config Object Initialization function.

void hbridge9_cfg_setup ( hbridge9_cfg_t *cfg );

• hbridge9_init Initialization function.

err_t hbridge9_init ( hbridge9_t *ctx, hbridge9_cfg_t *cfg );

• hbridge9_default_cfg Click Default Configuration function.

err_t hbridge9_default_cfg ( hbridge9_t *ctx );

• hbridge9_write_register This function writes a desired data to the selected register.

err_t hbridge9_write_register ( hbridge9_t *ctx, uint8_t reg, uint16_t data_in );

• hbridge9_read_register This function reads a desired data from the selected register.

err_t hbridge9_read_register ( hbridge9_t *ctx, uint8_t reg, uint16_t *data_out );

• hbridge9_send_actuation_pulse This function sends an actuation pulse by toggling the ENO pin.

void hbridge9_send_actuation_pulse ( hbridge9_t *ctx );

Application Init

Initializes the driver and performs the Click default configuration which will set the OUT1 to LOW, OUT2 to HIGH polarity, and the runtime to 1000ms.

void application_init ( void )
{
    log_cfg_t log_cfg;            /**< Logger config object. */
    hbridge9_cfg_t hbridge9_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.

    hbridge9_cfg_setup( &hbridge9_cfg );
    HBRIDGE9_MAP_MIKROBUS( hbridge9_cfg, MIKROBUS_1 );
    err_t init_flag = hbridge9_init( &hbridge9, &hbridge9_cfg );
    if ( SPI_MASTER_ERROR == init_flag )
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    init_flag = hbridge9_default_cfg ( &hbridge9 );
    if ( HBRIDGE9_ERROR == init_flag )
    {
        log_error( &logger, " Default Config Error. " );
        log_info( &logger, " Please, run program again... " );

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

Application Task

Sends an actuation pulse every 5 seconds which will run the motor for a certain amount of time as set by default configuration.

void application_task ( void )
{
    hbridge9_send_actuation_pulse( &hbridge9 );
    log_printf( &logger, " Actuation pulse has been sent. \r\n\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Note

The Voltage should be supplied with 6 to 18V power supply. Make sure to use a motor that operates in the above voltage range.

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.
