  • Author : Stefan Ilic
  • Date : Jun 2023.
  • Type : PWM type

Software Support

We provide a library for the DC Motor 27 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for DC Motor 27 Click driver.

Standard key functions :

  • dcmotor27_cfg_setup Config Object Initialization function.

    void dcmotor27_cfg_setup ( dcmotor27_cfg_t *cfg );
  • dcmotor27_init Initialization function.

    err_t dcmotor27_init ( dcmotor27_t *ctx, dcmotor27_cfg_t *cfg );
  • dcmotor27_default_cfg Click Default Configuration function.

    err_t dcmotor27_default_cfg ( dcmotor27_t *ctx );

Example key functions :

  • dcmotor27_set_duty_cycle DC Motor 27 sets PWM duty cycle.

    err_t dcmotor27_set_duty_cycle ( dcmotor27_t *ctx, float duty_cycle );
  • dcmotor27_get_flt_pin DC Motor 27 get flt pin state.

    uint8_t dcmotor27_get_flt_pin ( dcmotor27_t *ctx );
  • dcmotor27_set_coast DC Motor 27 set coast mode funtion.

    void dcmotor27_set_coast ( dcmotor27_t *ctx, uint8_t coast_state );

Example Description

This example demonstrates the use of the DC Motor 27 Click board by driving the motor at different speeds, enabling brake and coast modes.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    dcmotor27_cfg_t dcmotor27_cfg;  /**< Click config object. */

    /** 
     * 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.
    dcmotor27_cfg_setup( &dcmotor27_cfg );
    DCMOTOR27_MAP_MIKROBUS( dcmotor27_cfg, MIKROBUS_1 );
    if ( PWM_ERROR == dcmotor27_init( &dcmotor27, &dcmotor27_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    if ( DCMOTOR27_ERROR == dcmotor27_default_cfg ( &dcmotor27 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    log_info( &logger, " Application Task " );
}

Application Task

Controls the motor speed by changing the PWM duty cycle every second, places the motor into coast or braking mode.

void application_task ( void ) 
{
    for ( uint8_t speed_cnt = 10; speed_cnt <= 100; speed_cnt += 10 )
    {
        float speed = ( float ) speed_cnt / 100;
        dcmotor27_set_duty_cycle( &dcmotor27, speed );
        log_printf( &logger, " Motor speed %d%% \r\n", ( uint16_t ) speed_cnt );
        Delay_ms ( 1000 );
    }

    log_printf( &logger, " Motor coasting \r\n" );
    dcmotor27_set_coast( &dcmotor27, DCMOTOR27_SET_COAST_ON );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    dcmotor27_set_coast( &dcmotor27, DCMOTOR27_SET_COAST_OFF );

    for ( uint8_t speed_cnt = 10; speed_cnt <= 100; speed_cnt += 10 )
    {
        float speed = ( float ) speed_cnt / 100;
        dcmotor27_set_duty_cycle( &dcmotor27, speed );
        log_printf( &logger, " Motor speed %d%% \r\n", ( uint16_t ) speed_cnt );
        Delay_ms ( 1000 );
    }

    log_printf( &logger, " Motor brake is on \r\n" );
    dcmotor27_pwm_stop( &dcmotor27 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    dcmotor27_pwm_start( &dcmotor27 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.DCMotor27

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. UART terminal is available in all MikroElektronika compilers.

eFuse 4 Click

0

eFuse 4 Click is a compact add-on board with a power path protection solution that limits circuit currents and voltages to safe levels during fault conditions. This board features the TPS25940, an eFuse power switch with reverse current blocking from Texas Instruments. The TPS25940 features a full suite of protection and monitoring functions, including a DevSleep™ mode that supports compliance with the SATA™ Device Sleep standard. The wide operating range from 2.7V to 18V allows control of many popular DC bus voltages. The additional potentiometer sets the overload and short-circuit current limit of the TPS25940, while the additional header allows external current monitoring.

MUX 5 Click is a compact add-on board that contains a precise multiplexing solution. This board features the MAX14661, a serially controlled, dual-channel analog multiplexer from Analog Devices, allowing any of the 16 pins to be connected to either common pin simultaneously in any combination. The MAX14661 features Beyond-the-Rails™ capability that allows ±5.5V signals to be passed with any supply configuration alongside a configurable host interface that supports SPI and I2C serial communications. Both modes provide individual control of each independent switch so that any combination of switches can be applied.

Pressure 21 Click is a compact add-on board that contains a board-mount pressure sensor. This board features the BMP581, an absolute barometric pressure sensor from Bosch Sensortec. The BMP581 provides a relative accuracy of ±6Pa and typical absolute accuracy of ±30Pa with ultra-low noise, low power consumption, and temperature stability alongside programmable output: temperature-only or both pressure and temperature (pressure-only is not supported). It converts output data into a 24-bit digital value and sends the information via a configurable host interface that supports SPI and I2C serial communications. It measures pressure from 30kPa up to 125kPa over a wide operating temperature range.
