H-Bridge 6 Click

H-Bridge 6 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 is an example that demonstrates the use of H-Bridge 6 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.HBridge6

Example Key Functions

• hbridge6_cfg_setup Config Object Initialization function.

void hbridge6_cfg_setup ( hbridge6_cfg_t *cfg );

• hbridge6_init Initialization function.

err_t hbridge6_init ( hbridge6_t *ctx, hbridge6_cfg_t *cfg );

• hbridge6_default_cfg Click Default Configuration function.

err_t hbridge6_default_cfg ( hbridge6_t *ctx );

• hbridge6_reset HW reset function.

void hbridge6_reset ( hbridge6_t *ctx );

• hbridge6_enable_diagnostic Enable the diagnostic function.

void hbridge6_enable_diagnostic ( hbridge6_t *ctx, uint8_t en_state );

• hbridge6_set_direction Adjust the direction function.

void hbridge6_set_direction ( hbridge6_t *ctx, uint8_t direction );

Application Init

Initialization driver enables - I2C, reset the device and set default configuration, initialization and configure the PWM, also write log.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    hbridge6_cfg_t hbridge6_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.
    hbridge6_cfg_setup( &hbridge6_cfg );
    HBRIDGE6_MAP_MIKROBUS( hbridge6_cfg, MIKROBUS_1 );
    err_t init_flag = hbridge6_init( &hbridge6, &hbridge6_cfg );
    if ( I2C_MASTER_ERROR == init_flag || PWM_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );
        for ( ; ; );
    }
    log_printf( &logger, "-----------------------\r\n" );
    log_printf( &logger, "  Set default config.  \r\n" );
    log_printf( &logger, "-----------------------\r\n" );
    hbridge6_default_cfg( &hbridge6 );
    Delay_ms ( 100 );
    
    log_info( &logger, " Application Task " );
}

Application Task

It shows moving in the clockwise direction of rotation and moving in the counterclockwise direction of rotation from slow to fast speed. All data logs write on USB uart changes.

void application_task ( void ) 
{
    static int8_t duty_cnt = 1;
    static int8_t duty_inc = 1;
    float duty = 0;
    
    log_printf( &logger, "       Clockwise       \r\n" );
    log_printf( &logger, "-----------------------\r\n" );
    hbridge6_set_direction( &hbridge6, HBRIDGE6_DIRECTION_CLOCKWISE );
    
    while ( duty_cnt < 10 ) {
        duty = duty_cnt / 10.0;
        hbridge6_set_duty_cycle ( &hbridge6, duty );
        Delay_ms ( 500 );
        duty_cnt += duty_inc;
    }
    
    log_printf( &logger, "         Brake         \r\n" );
    log_printf( &logger, "-----------------------\r\n" );
    hbridge6_set_direction( &hbridge6, HBRIDGE6_DIRECTION_BRAKE );
    duty_cnt = 1;
    Delay_ms ( 1000 );
    
    log_printf( &logger, "    Counterclockwise   \r\n" );
    log_printf( &logger, "-----------------------\r\n" );
    hbridge6_set_direction( &hbridge6, HBRIDGE6_DIRECTION_COUNTERCLOCKWISE );
    
    while ( duty_cnt < 10 ) {
        duty = duty_cnt / 10.0;
        hbridge6_set_duty_cycle ( &hbridge6, duty );
        Delay_ms ( 500 );
        duty_cnt += duty_inc;
    }
    
    log_printf( &logger, "         Brake         \r\n" );
    log_printf( &logger, "-----------------------\r\n" );
    hbridge6_set_direction( &hbridge6, HBRIDGE6_DIRECTION_BRAKE );
    duty_cnt = 1;
    
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    hbridge6_pwm_stop( &hbridge6 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    hbridge6_pwm_start( &hbridge6 );
}

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.
