H BRIDGE 2 Click

H-Bridge 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

• Type : GPIO type

Software Support

Example Description

This application controls the speed and direction of motor.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.HBridge2

Example Key Functions

• hbridge2_cfg_setup Config Object Initialization function.

void hbridge2_cfg_setup ( hbridge2_cfg_t *cfg );

• hbridge2_init Initialization function.

err_t hbridge2_init ( hbridge2_t *ctx, hbridge2_cfg_t *cfg );

• hbridge2_set_output Output Set function.

uint8_t hbridge2_set_output ( hbridge2_t *ctx, uint8_t out_state );

• hbridge2_enable Enable function.

void hbridge2_enable ( hbridge2_t *ctx, uint8_t state );

• hbridge2_set_gout GOUT Set function.

void hbridge2_set_gout ( hbridge2_t *ctx, uint8_t state );

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 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
