H-Bridge 15 click

H-Bridge 15 Click is a compact add-on board with an H-Bridge gate driver, also known as a full-bridge pre-driver. This board features the DRV8834, a dual-bridge stepper or DC motor driver from Texas Instruments.

Software Support

We provide a library for the H-Bridge 15 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for H-Bridge 15 Click driver.

Standard key functions :

• hbridge15_cfg_setup Config Object Initialization function.

  void hbridge15_cfg_setup ( hbridge15_cfg_t *cfg );

• hbridge15_init Initialization function.

  err_t hbridge15_init ( hbridge15_t *ctx, hbridge15_cfg_t *cfg );

• hbridge15_default_cfg Click Default Configuration function.

  err_t hbridge15_default_cfg ( hbridge15_t *ctx );

Example key functions :

• hbridge15_set_pins H-Bridge 15 set pins function.

  err_t hbridge15_set_pins ( hbridge15_t *ctx, uint8_t set_mask, uint8_t clr_mask );

• hbridge15_set_sleep H-Bridge 15 set sleep function.

  err_t hbridge15_set_sleep ( hbridge15_t *ctx, uint8_t sleep_state );

• hbridge15_set_out_state H-Bridge 15 set output function.

  err_t hbridge15_set_out_state ( hbridge15_t *ctx, uint8_t out_state );

Example Description

This example demonstrates the use of the H-Bridge 15 click board by driving the motor in both directions with braking and freewheeling.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    hbridge15_cfg_t hbridge15_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.
    hbridge15_cfg_setup( &hbridge15_cfg );
    HBRIDGE15_MAP_MIKROBUS( hbridge15_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == hbridge15_init( &hbridge15, &hbridge15_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( HBRIDGE15_ERROR == hbridge15_default_cfg ( &hbridge15 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

This example is driving a motor in both directions with motor braking and freewheeling in between.

void application_task ( void ) 
{
    log_printf( &logger, " Motor in forward mode. \r\n" );
    hbridge15_set_out_state( &hbridge15, HBRIDGE15_DRIVE_MOTOR_FORWARD );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, " Motor brake is on \r\n" );
    hbridge15_set_out_state( &hbridge15, HBRIDGE15_DRIVE_MOTOR_BRAKE );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, " Motor in reverse mode. \r\n" );
    hbridge15_set_out_state( &hbridge15, HBRIDGE15_DRIVE_MOTOR_REVERSE );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, " Motor is coasting \r\n" );
    hbridge15_set_out_state( &hbridge15, HBRIDGE15_DRIVE_MOTOR_FREEWHEEL );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.HBridge15

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
