H-Bridge 13 Click

H-Bridge 13 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 DRV8411A, a dual H-bridge motor driver with current regulations from Texas Instruments. It can drive one bipolar stepper motor, one or two brushed DC motors, solenoids, and other inductive loads.

Click library

• Author : Stefan Ilic
• Date : Jun 2023.
• Type : I2C type

Software Support

We provide a library for the H-Bridge 13 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 13 Click driver.

Standard key functions :

• hbridge13_cfg_setup Config Object Initialization function.

void hbridge13_cfg_setup ( hbridge13_cfg_t *cfg );

• hbridge13_init Initialization function.

err_t hbridge13_init ( hbridge13_t *ctx, hbridge13_cfg_t *cfg );

• hbridge13_default_cfg Click Default Configuration function.

err_t hbridge13_default_cfg ( hbridge13_t *ctx );

Example key functions :

• hbridge13_write_reg H-Bridge 13 write register function.

err_t hbridge13_write_reg ( hbridge13_t *ctx, uint8_t reg, uint8_t data_out );

• hbridge13_set_direction H-Bridge 13 set direction function.

err_t hbridge13_set_direction ( hbridge13_t *ctx, uint8_t dir_set, uint8_t speed );

• hbridge13_get_an_voltage H-Bridge 13 get xIPROPI voltage function.

err_t hbridge13_get_an_voltage ( hbridge13_t *ctx, float *voltage, uint8_t an_sel );

Example Description

This example demonstrates the use of the H-Bridge 13 Click board by driving the motor connected to OUT A and OUT B, 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. */
    hbridge13_cfg_t hbridge13_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.
    hbridge13_cfg_setup( &hbridge13_cfg );
    HBRIDGE13_MAP_MIKROBUS( hbridge13_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == hbridge13_init( &hbridge13, &hbridge13_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( HBRIDGE13_ERROR == hbridge13_default_cfg ( &hbridge13 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

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

void application_task ( void ) 
{
    for( uint8_t n_cnt = 0; n_cnt <= 100; n_cnt += 10 )
    {
        log_printf( &logger, " Motor in forward mode with speed of %d %% \r\n", ( uint16_t ) n_cnt );
        hbridge13_set_direction( &hbridge13, HBRIDGE13_DIR_FORWARD, n_cnt );
        Delay_ms ( 1000 );
    }
    
    log_printf( &logger, " Motor brake is on \r\n" );
    hbridge13_set_brake( &hbridge13 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    
    for( uint8_t n_cnt = 0; n_cnt <= 100; n_cnt += 10 )
    {
        log_printf( &logger, " Motor in reverse with speed of %d %% \r\n", ( uint16_t ) n_cnt );
        hbridge13_set_direction( &hbridge13, HBRIDGE13_DIR_REVERSE, n_cnt );
        Delay_ms ( 1000 );
    }
    
    log_printf( &logger, " Motor is coasting \r\n" );
    hbridge13_set_coast( &hbridge13 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    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.HBridge13

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.
