H-Bridge 10 Click

H-Bridge 10 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.

• Type : SPI type

Software Support

Example Description

This example demonstrates the use of the H-Bridge 10 Click board by driving the motors connected between OUT1-OUT2 and OUT2-OUT3 in both directions.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.HBridge10

Example Key Functions

• hbridge10_cfg_setup Config Object Initialization function.

void hbridge10_cfg_setup ( hbridge10_cfg_t *cfg );

• hbridge10_init Initialization function.

err_t hbridge10_init ( hbridge10_t *ctx, hbridge10_cfg_t *cfg );

• hbridge10_default_cfg Click Default Configuration function.

err_t hbridge10_default_cfg ( hbridge10_t *ctx );

• hbridge10_set_output_state This function sets the output channel state.

err_t hbridge10_set_output_state ( hbridge10_t *ctx, uint8_t channel, uint8_t state );

• hbridge10_get_status This function reads the status of output register.

err_t hbridge10_get_status ( hbridge10_t *ctx, uint16_t *status );

• hbridge10_get_fault_pin This function returns the fault (FLT) pin logic state.

uint8_t hbridge10_get_fault_pin ( hbridge10_t *ctx );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    hbridge10_cfg_t hbridge10_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.
    hbridge10_cfg_setup( &hbridge10_cfg );
    HBRIDGE10_MAP_MIKROBUS( hbridge10_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == hbridge10_init( &hbridge10, &hbridge10_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( HBRIDGE10_ERROR == hbridge10_default_cfg ( &hbridge10 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Drives the motors connected between OUT1-OUT2 and OUT2-OUT3 in both directions in the span of 6 seconds, and displays the status messages on the USB UART.

void application_task ( void )
{
    uint16_t status;
    if ( ( HBRIDGE10_OK == hbridge10_set_output_state ( &hbridge10, HBRIDGE10_CHANNEL_OUT1, HBRIDGE10_OUT_HIGH ) ) && 
         ( HBRIDGE10_OK == hbridge10_set_output_state ( &hbridge10, HBRIDGE10_CHANNEL_OUT2, HBRIDGE10_OUT_LOW ) ) && 
         ( HBRIDGE10_OK == hbridge10_set_output_state ( &hbridge10, HBRIDGE10_CHANNEL_OUT3, HBRIDGE10_OUT_HIGH ) ) )
    {
        Delay_ms ( 100 );
        if ( HBRIDGE10_OK == hbridge10_get_status ( &hbridge10, &status ) )
        {
            hbridge10_display_status ( status );
            Delay_ms ( 1000 );
            Delay_ms ( 1000 );
            Delay_ms ( 1000 );
        }
    }
    if ( ( HBRIDGE10_OK == hbridge10_set_output_state ( &hbridge10, HBRIDGE10_CHANNEL_OUT1, HBRIDGE10_OUT_LOW ) ) && 
         ( HBRIDGE10_OK == hbridge10_set_output_state ( &hbridge10, HBRIDGE10_CHANNEL_OUT2, HBRIDGE10_OUT_HIGH ) ) && 
         ( HBRIDGE10_OK == hbridge10_set_output_state ( &hbridge10, HBRIDGE10_CHANNEL_OUT3, HBRIDGE10_OUT_LOW ) ) )
    {
        Delay_ms ( 100 );
        if ( HBRIDGE10_OK == hbridge10_get_status ( &hbridge10, &status ) )
        {
            hbridge10_display_status ( status );
            Delay_ms ( 1000 );
            Delay_ms ( 1000 );
            Delay_ms ( 1000 );
        }
    }
}

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.
