Click library

• Author : MikroE Team
• Date : Jun 2020.
• Type : GPIO type

Software Support

We provide a library for the Dcmotor14 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 Dcmotor14 Click driver.

Standard key functions :

• Config Object Initialization function.

void dcmotor14_cfg_setup ( dcmotor14_cfg_t *cfg );

• Initialization function.

DCMOTOR14_RETVAL dcmotor14_init ( dcmotor14_t *ctx, dcmotor14_cfg_t *cfg );

Example key functions :

• This functio is used to drive the motor forward.

void dcmotor14_forward ( dcmotor14_t *ctx );

• This functio is used to drive the motor in reverse.

dcmotor14_reverse ( dcmotor14_t *ctx );

• This functio is used to brake the motor.

dcmotor14_brake ( dcmotor14_t *ctx );

Examples Description

This example demonstrates the use of DC Motor 14 click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    dcmotor14_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.

    dcmotor14_cfg_setup( &cfg );
    DCMOTOR14_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    dcmotor14_init( &dcmotor14, &cfg );
}
  

Application Task

Drives the motor in the forward direction for 5 seconds, then pulls brake for 2 seconds, and after that drives it in the reverse direction for 5 seconds, and finally, disconnects the motor for 2 seconds. Each step will be logged on the USB UART where you can track the program flow.

void application_task ( void )
{
    log_printf( &logger, "The motor turns forward! \r\n" );
    dcmotor14_forward( &dcmotor14 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, "Pull brake! \r\n" );
    dcmotor14_brake( &dcmotor14 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, "The motor turns in reverse! \r\n" );
    dcmotor14_reverse( &dcmotor14 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, "The motor is disconnected (High-Z)!  \r\n" );
    dcmotor14_stop( &dcmotor14 );
    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.Dcmotor14

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.
