Click library

  • Author : Nikola Peric
  • Date : Feb 2022.
  • Type : PWM type

Software Support

We provide a library for the HBridge3 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for HBridge3 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void hbridge3_cfg_setup ( hbridge3_cfg_t *cfg );

  • Initialization function.

    HBRIDGE3_RETVAL hbridge3_init ( hbridge3_t ctx, hbridge3_cfg_t cfg );

  • Click Default Configuration function.

    void hbridge3_default_cfg ( hbridge3_t *ctx );

Example key functions :

  • This function sets the PWM duty cycle.

    void hbridge3_set_duty_cycle ( hbridge3_t *ctx, pwm_data_t duty_cycle );

  • This function sends SPI command and receives response to command sent

    uint8_t hbridge3_spi ( hbridge3_t *ctx, uint8_t spi_command );

  • Generic SPI transfer, for sending and receiving packages.

    void hbridge3_generic_transfer ( hbridge3_t ctx, spi_master_transfer_data_t block );

Examples Description

H-bridge in general, allows the current to flow in one or another direction. This Click is used for drive a H-Bridge motor by changing output states. The outputs can be pulse width modulated at frequencies up to 20kHz by means of PWM/DIR control.

The demo application is composed of two sections :

Application Init

Initializes SPI and LOG modules, AN, RST, CS and PWM pins


void application_init ( void )
{
    log_cfg_t log_cfg;
    hbridge3_cfg_t cfg;

    /** 
     * 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.

    hbridge3_cfg_setup( &cfg );
    HBRIDGE3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    hbridge3_init( &hbridge3, &cfg );
    Delay_ms ( 500 );

    hbridge3_pwm_start( &hbridge3 );
    log_info( &logger, "---- Application Task ----" );
    log_printf( &logger, "> CLOCKWISE <\r\n" );
}

Application Task

This example demonstrates the use of H-Bridge 3 Click board, by running dc motor in both directions - increasing and decreasing PWM duty cycle. Results are being sent to the Usart Terminal where you can track their changes.


void application_task ( void )
{
    static int8_t duty_cnt = 1;
    static int8_t duty_inc = 1;
    float duty = duty_cnt / 10.0;


    hbridge3_set_duty_cycle ( &hbridge3, duty );
    log_printf( &logger, " Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );
    Delay_ms ( 500 );

    if ( 10 == duty_cnt ) 
    {
        duty_inc = -1;
    }
    else if ( 0 == duty_cnt ) 
    {
        duty_inc = 1;

        if ( motor_direction == 1 )
        {
            log_printf( &logger, "> COUNTER CLOCKWISE <\r\n" );
            motor_direction = 0;
             hbridge3_dir_set ( &hbridge3 , 0 );
        }
        else if ( motor_direction == 0 )
        {
            log_printf( &logger, "> CLOCKWISE <\r\n" );
            motor_direction = 1;
            hbridge3_dir_set ( &hbridge3 , 1 );
        }
    }
    duty_cnt += duty_inc;
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.HBridge3

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.

UV click

5

With UV click you can measure Ultraviolet light intensity both indoors and outdoors. The photodiode on the ML8511 IC is sensitive to UV-A (365–315 nm) and UV-B (315-280) rays. You can use UV click to design devices that protect the user against excesive sun exposure, or for industrial purposes where UV light is used for sterilization.
