H-Bridge 4 click

H-Bridge 4 Click is a Click board™ that contains the AP1010AEN, which is a two channel H-Bridge motor driver compatible with a motor operating voltage up to 18V and can drive two DC motors or one stepper motor.

Click library

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

Software Support

We provide a library for the HBridge4 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 HBridge4 Click driver.

Standard key functions :

• Config Object Initialization function.

void hbridge4_cfg_setup ( hbridge4_cfg_t *cfg );

• Initialization function.

HBRIDGE4_RETVAL hbridge4_init ( hbridge4_t *ctx, hbridge4_cfg_t *cfg );

Example key functions :

• Enable the device function

void hbridge4_enable ( hbridge4_t *ctx, uint8_t state );

• Set IN1 function

void hbridge4_set_in1 ( hbridge4_t *ctx, uint8_t state );

• Motor A standby function

void hbridge4_motor_a_standby ( hbridge4_t *ctx );

Examples Description

This application is used to turn on DC or Stepper motors.

The demo application is composed of two sections :

Application Init

Initialization driver enables GPIO and also starts write log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    hbridge4_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 ----\r\n" );

    //  Click initialization.

    hbridge4_cfg_setup( &cfg );
    HBRIDGE4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    hbridge4_init( &hbridge4, &cfg );

    hbridge4_enable( &hbridge4, 1 );
    Delay_ms( 100 );
    log_printf( &logger, "------------------- \r\n" );
    log_printf( &logger, " H-Bridge 4 click \r\n" );
    log_printf( &logger, "------------------- \r\n" );
}
  

Application Task

This example demonstrates the use of H-Bridge 4 click board by putting A motor in standby mode, then spining it in clockwise direction and applying brake function, and then spining it in counter-clockwise direction and applying brake function again.

void application_task ( )
{
    log_printf( &logger, "The motor A is in standby mode \r\n" );
    hbridge4_motor_a_standby( &hbridge4 );
    Delay_ms( 100 );
    log_printf( &logger, "The motor A turns clockwise \r\n" );
    hbridge4_motor_acw( &hbridge4 );
    Delay_ms( 2000 );
    log_printf( &logger, "The motor A applies brake \r\n" );
    hbridge4_motor_a_brake( &hbridge4 );
    Delay_ms( 1000 );
    log_printf( &logger, "The motor A turns counter-clockwise \r\n" );
    hbridge4_motor_accw( &hbridge4 );
    Delay_ms( 2000 );
    log_printf( &logger, "The motor A applies brake \r\n" );
    hbridge4_motor_a_brake( &hbridge4 );
    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.HBridge4

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.
