H-Bridge 12 Click

H Bridge 12 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 DRV8823, a 4-bridge serial interface motor driver from Texas Instruments.

Click library

  • Author : Stefan Ilic
  • Date : Apr 2023.
  • Type : SPI type

Software Support

We provide a library for the H-Bridge 12 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 12 Click driver.

Standard key functions :

  • hbridge12_cfg_setup Config Object Initialization function.

    void hbridge12_cfg_setup ( hbridge12_cfg_t *cfg );
  • hbridge12_init Initialization function.

    err_t hbridge12_init ( hbridge12_t *ctx, hbridge12_cfg_t *cfg );
  • hbridge12_default_cfg Click Default Configuration function.

    err_t hbridge12_default_cfg ( hbridge12_t *ctx );

Example key functions :

  • hbridge12_write_config H-Bridge 12 write settings function.

    err_t hbridge12_write_config ( hbridge12_t *ctx, hbridge12_config_t config_data );
  • hbridge12_set_current_scale H-Bridge 12 set current scale function.

    void hbridge12_set_current_scale ( hbridge12_t *ctx, uint8_t channel_sel, uint8_t out1_curr_scale, uint8_t out2_curr_scale );
  • hbridge12_turn_clockwise H-Bridge 12 turn motor clockwise function.

    err_t hbridge12_turn_clockwise ( hbridge12_t *ctx, uint8_t channel_sel );

Example Description

This example demonstrates the use of the H-Bridge 12 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. */
    hbridge12_cfg_t hbridge12_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.
    hbridge12_cfg_setup( &hbridge12_cfg );
    HBRIDGE12_MAP_MIKROBUS( hbridge12_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == hbridge12_init( &hbridge12, &hbridge12_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( HBRIDGE12_ERROR == hbridge12_default_cfg ( &hbridge12 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

Driving motor in both directions for 5 seconds with a motor braking and freewheeling in between.

void application_task ( void )
{
    log_printf( &logger, " Turning motor counterclockwise \r\n" );
    hbridge12_turn_counterclockwise( &hbridge12, HBRIDGE12_AB_BRIDGE_SEL );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, " Turning motor brake on \r\n" );
    hbridge12_turn_brake_on( &hbridge12, HBRIDGE12_AB_BRIDGE_SEL );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, " Turning motor clockwise \r\n" );
    hbridge12_turn_clockwise( &hbridge12, HBRIDGE12_AB_BRIDGE_SEL );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, " Motor freewheeling \r\n" );
    hbridge12_freewheeling_on( &hbridge12, HBRIDGE12_AB_BRIDGE_SEL );
    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.HBridge12

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.
