Click library

  • Author : Stefan Ilic
  • Date : Jul 2021.
  • Type : I2C type

Software Support

We provide a library for the HBridge6 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 HBridge6 Click driver.

Standard 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 );

Example key functions :

  • 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 );

Example Description

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

The demo application is composed of two sections :

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 );
}

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.HBridge6

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.
