• Type : I2C type

Software Support

We provide a library for the DcMotor7 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 DcMotor7 Click driver.

Standard key functions :

• Config Object Initialization function.

  void dcmotor7_cfg_setup ( dcmotor7_cfg_t *cfg );

• Initialization function.

  DCMOTOR7_RETVAL dcmotor7_init ( dcmotor7_t ctx, dcmotor7_cfg_t cfg );

• Default Configuration

  void dcmotor7_default_cfg ( dcmotor7_t *ctx );

Example key functions :

• Functions for set port

  void dcmotor7_set_port ( dcmotor7_t *ctx, uint8_t port, uint8_t value );

• Function for setting the motor in stand mode

  void dcmotor7_go_to_stand_by_mode ( dcmotor7_t *ctx, uint8_t motor );

• Function for set PWM value for motor B

  void dcmotor7_set_pwm_motor_b ( dcmotor7_t *ctx, uint8_t state );

Examples Description

This application is a dual brushed DC motor driving.

The demo application is composed of two sections :

Application Init

Initialization driver init, enabled all output port, sets H-Bridge operation mode and Motor Digital tblk

void application_init ( void )
{
    log_cfg_t log_cfg;
    dcmotor7_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.

    dcmotor7_cfg_setup( &cfg );
    DCMOTOR7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    dcmotor7_init( &dcmotor7, &cfg );

    dcmotor7_default_cfg( &dcmotor7 );
}

Application Task

Set the motor A and the motor B to rotate clockwise and in the Counte clockwise direction, and between the change of direction, the motor stops the motor.

void application_task ( void )
{
    dcmotor7_set_motor( &dcmotor7, DCMOTOR7_MOTOR_A, 0, 1 );
    dcmotor7_set_motor( &dcmotor7, DCMOTOR7_MOTOR_B, 0, 1 );
    Delay_ms ( 500 );

    dcmotor7_motor_stop( &dcmotor7, DCMOTOR7_MOTOR_A );
    dcmotor7_motor_stop( &dcmotor7, DCMOTOR7_MOTOR_B );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    dcmotor7_set_motor( &dcmotor7, DCMOTOR7_MOTOR_A, 1, 0 );
    dcmotor7_set_motor( &dcmotor7, DCMOTOR7_MOTOR_B, 1, 0 );
    Delay_ms ( 500 );

    dcmotor7_motor_stop( &dcmotor7, DCMOTOR7_MOTOR_A );
    dcmotor7_motor_stop( &dcmotor7, DCMOTOR7_MOTOR_B );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
} 

Note

VM input - 10 V (min) to 47 V (max)

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.DcMotor7

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.
