H BRIDGE 2 Click

< H-Bridge 2 Click can be used to drive a motor by utilizing a specific configuration of the output stage MOSFETs, known as the H-bridge. This configuration enables H-Bridge 2 Click to drive a motor with up to 1.2A and 15V, providing control of the speed and direction, as well as the dynamic (rheostatic) braking capability >

Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : GPIO type

Software Support

We provide a library for the HBridge2 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 HBridge2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void hbridge2_cfg_setup ( hbridge2_cfg_t *cfg );

  • Initialization function.

    HBRIDGE2_RETVAL hbridge2_init ( hbridge2_t ctx, hbridge2_cfg_t cfg );

Example key functions :

  • Output Set function.

    uint8_t hbridge2_set_output ( hbridge2_t *ctx, uint8_t out_state );

  • Enable function.

    void hbridge2_enable ( hbridge2_t *ctx, uint8_t state );

  • GOUT Set function.

    void hbridge2_set_gout ( hbridge2_t *ctx, uint8_t state );

Examples Description

This application controls the speed and direction of motor.

The demo application is composed of two sections :

Application Init

Initializes GPIO driver and puts the device to enable state, and the GPIO pin to logic high state.


void application_init ( void )
{
    log_cfg_t log_cfg;
    hbridge2_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.

    hbridge2_cfg_setup( &cfg );
    HBRIDGE2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    hbridge2_init( &hbridge2, &cfg );

    hbridge2_enable( &hbridge2, HBRIDGE2_ENABLE );
    hbridge2_set_gout( &hbridge2, HBRIDGE2_GOUT_HIGH );
    log_printf( &logger, "H-Bridge 2 is intialized\r\n" );
    Delay_ms ( 200 );
}
}

Application Task

Demonstrates the control of output pins by put output pins to different states. The outputs be changed after every 3 seconds.


void application_task ( void )
{
    hbridge2_set_output( &hbridge2, HBRIDGE2_OUT1_H_OUT2_L );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    hbridge2_set_output( &hbridge2, HBRIDGE2_OUT1_L_OUT2_H );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    hbridge2_set_output( &hbridge2, HBRIDGE2_OUT1_Z_OUT2_Z );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}  

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.HBridge2

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.

4x4 RGB 2 Click is a compact add-on board that contains a matrix of 16 intelligent RGB LEDs, forming a 4x4 display screen. This board features 16 IN-PC55TBTRGB, 5x5mm RGB LEDs with an integrated IC from Inolux. The LEDs feature an 8-bit color control in 256 steps (256-level greyscale) and a 5-bit brightness control in 32 steps. The intelligent LEDs are cascaded (daisy-chained); thus, every one of them can communicate with the host MCU using the same data lines.
