Click library

  • Author : MikroE Team
  • Date : jan 2020.
  • Type : PWM type

Software Support

We provide a library for the DcMotor5 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 DcMotor5 Click driver.

Standard key functions :

Example key functions :

  • Function brakes the engine by setting IN1 ( PWM ) and IN2 ( INT ) pins on DC Motor 5 Click board.

    void dcmotor5_short_brake ( dcmotor5_t *ctx );

  • Function stops the engine by clearing IN1 ( PWM ) and IN2 ( INT ) pins on DC Motor 5 Click board.

    void dcmotor5_stop ( dcmotor5_t *ctx );

  • Function disables the engine by clearing SLEEP ( RST ) pin on DC Motor 5 Click board.

    void dcmotor5_enable ( dcmotor5_t *ctx );

Examples Description

This applciation enables usage of brushed DC motor gate driver.

The demo application is composed of two sections :

Application Init

Initializes GPIO, PWM and logger and enables the click board.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
LOG_MAP_USB_UART( log_cfg );
log_cfg.level = LOG_LEVEL_DEBUG;
log_cfg.baud = 9600;
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
DCMOTOR5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
dcmotor5_init( &dcmotor5, &cfg );
dcmotor5_pwm_start( &dcmotor5 );
dcmotor5_enable( &dcmotor5 );
Delay_1sec( );
}

Application Task

This function drives the motor in both directions increasing and decreasing the speed of the motor. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void )
{
clockwise( );
pull_brake( );
counter_clockwise( );
high_z( );
}

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.DcMotor5

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.
