H-Bridge 14 Click

H-Bridge 14 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.


Click Library

  • Author : Stefan Ilic
  • Date : Sep 2023.
  • Type : I2C/SPI type

Software Support

Example Description

This example demonstrates the use of the H-Bridge 14 board by driving the motor in both directions with braking and coasting in between.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.HBridge14

Example Key Functions

  • hbridge14_cfg_setup Config Object Initialization function.
void hbridge14_cfg_setup ( hbridge14_cfg_t *cfg );
  • hbridge14_init Initialization function.
err_t hbridge14_init ( hbridge14_t *ctx, hbridge14_cfg_t *cfg );
  • hbridge14_default_cfg Click Default Configuration function.
err_t hbridge14_default_cfg ( hbridge14_t *ctx );
  • hbridge14_set_pins H-Bridge 14 set pins function.
err_t hbridge14_set_pins ( hbridge14_t *ctx, uint8_t set_mask, uint8_t clr_mask );
  • hbridge14_sleep_state H-Bridge 14 control sleep function.
err_t hbridge14_sleep_state ( hbridge14_t *ctx, uint8_t sleep_state );
  • hbridge14_drive_motor H-Bridge 14 drive motor function.
err_t hbridge14_drive_motor ( hbridge14_t *ctx, uint8_t state );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    hbridge14_cfg_t hbridge14_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.
    hbridge14_cfg_setup( &hbridge14_cfg );
    HBRIDGE14_MAP_MIKROBUS( hbridge14_cfg, MIKROBUS_1 );
    err_t init_flag = hbridge14_init( &hbridge14, &hbridge14_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( HBRIDGE14_ERROR == hbridge14_default_cfg ( &hbridge14 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Drives the motor in both directions with coasting and braking in between, every sate is lasting 5 seconds.

void application_task ( void )
{
    uint8_t fault_status = 0;

    hbridge14_drive_motor( &hbridge14, HBRIDGE14_DRIVE_MOTOR_CW );
    log_printf( &logger, " Driving motor Clockwise \r\n" );
    hbridge14_register_read( &hbridge14, HBRIDGE14_REG_FAULT_STATUS, &fault_status );
    log_printf( &logger, " Fault status : 0x%.2X \r\n", ( uint16_t ) fault_status );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    
    hbridge14_drive_motor( &hbridge14, HBRIDGE14_DRIVE_MOTOR_BRAKE );
    log_printf( &logger, " Brake is on \r\n" );
    hbridge14_register_read( &hbridge14, HBRIDGE14_REG_FAULT_STATUS, &fault_status );
    log_printf( &logger, " Fault status : 0x%.2X \r\n", ( uint16_t ) fault_status );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    
    hbridge14_drive_motor( &hbridge14, HBRIDGE14_DRIVE_MOTOR_CCW );
    log_printf( &logger, " Driving motor counter-clockwise \r\n" );
    hbridge14_register_read( &hbridge14, HBRIDGE14_REG_FAULT_STATUS, &fault_status );
    log_printf( &logger, " Fault status : 0x%.2X \r\n", ( uint16_t ) fault_status );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    
    hbridge14_drive_motor( &hbridge14, HBRIDGE14_DRIVE_MOTOR_COASTING );
    log_printf( &logger, " Driving motor Coasting \r\n" );
    hbridge14_register_read( &hbridge14, HBRIDGE14_REG_FAULT_STATUS, &fault_status );
    log_printf( &logger, " Fault status : 0x%.2X \r\n", ( uint16_t ) fault_status );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    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.
