Click library

  • Author : Nikola Peric
  • Date : Feb 2022.
  • Type : PWM type

Software Support

We provide a library for the Stspin250 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 Stspin250 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void stspin250_cfg_setup ( stspin250_cfg_t *cfg );

  • Initialization function.

    STSPIN250_RETVAL stspin250_init ( stspin250_t ctx, stspin250_cfg_t cfg );

  • Click Default Configuration function.

    void stspin250_default_cfg ( stspin250_t *ctx );

Example key functions :

  • This function regulates Direction control pin state. It controls direction

  • of the current.

    void stspin250_set_ph ( stspin250_t *ctx, uint8_t state );

  • This function regulates enable pin state.

    void stspin250_enable ( stspin250_t *ctx, uint8_t state);

  • This function regulates reset pin state.

    void stspin250_reset ( stspin250_t *ctx );

Examples Description

This application enables usage of brushed DC motor driver with the current limiting and current sensing.

The demo application is composed of two sections :

Application Init

Initialization driver init, PWM init and enable device


void application_init ( void )
{
    log_cfg_t log_cfg;
    stspin250_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.

    stspin250_cfg_setup( &cfg );
    STSPIN250_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    stspin250_init( &stspin250, &cfg );

    stspin250_enable( &stspin250, STSPIN250_DEVICE_ENABLE );
    stspin250_set_duty_cycle ( &stspin250, 0.0 );

    stspin250_pwm_start( &stspin250 );
    log_info( &logger, "---- Application Task ----" );
    Delay_ms ( 500 );
}

Application Task

This is a example which demonstrates the use of Stspin250 Click board. Stspin250 Click communicates with register via PWM interface. It shows moving in the left direction from slow to fast speed and from fast to slow speed. Results are being sent to the Usart Terminal where you can track their changes.


void application_task ( void )
{
    static int8_t duty_cnt = 1;
    static int8_t duty_inc = 1;
    float duty = duty_cnt / 10.0;

    if ( motor_direction == 1 )
    {
        stspin250_set_ph( &stspin250, 1 );
        log_printf( &logger, "> CLOCKWISE <\r\n" );
    }
    else
    {
        stspin250_set_ph( &stspin250, 0 );
        log_printf( &logger, "> COUNTER CLOCKWISE <\r\n" );
    }

    stspin250_set_duty_cycle ( &stspin250, duty );
    log_printf( &logger, "Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );
    Delay_ms ( 500 );

    if ( 10 == duty_cnt ) 
    {
        duty_inc = -1;
    }
    else if ( 0 == duty_cnt ) 
    {
        duty_inc = 1;
        if ( motor_direction == 1 )
        {
            motor_direction = 0;
        }
        else if ( motor_direction == 0 )
        {
            motor_direction = 1;
        }
    }
    duty_cnt += duty_inc;
}

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.Stspin250

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.

Stepper 23 Click is a compact add-on board designed to drive small stepping motors in consumer electronics and industrial equipment applications. This board features the TB67S569FTG, a BiCD constant-current 2-phase bipolar stepping motor driver IC from Toshiba Semiconductor. Key features include a PWM chopper-type 2-phase bipolar drive system, high withstand voltage of up to 34V operating, and a maximum operating current of 1.8A per phase. The board also integrates safety mechanisms such as over-temperature, over-current, and low-supply voltage detection. Additional control is provided by the PCA9555A port expander via I2C, enabling functions like decay and torque modes, step resolution settings, and many more.
