Stepper 12 Click is a compact add-on board that contains a bipolar stepper motor driver. This board features the TB67S549FTG, a two-phase bipolar stepping motor driver from Toshiba Semiconductor. It supports a PWM constant-current control drive without a current sense resistor for motor-current detection and allows full-step to 1/32 steps resolution for less motor noise and smoother control. It has a wide operating voltage range of 4.5V to 34V with an output current capacity of 1.2A maximum and several anomaly detection indicators.

Click library

  • Author : Stefan Filipovic
  • Date : Sep 2022.
  • Type : I2C type

Software Support

We provide a library for the Stepper 12 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 Stepper 12 Click driver.

Standard key functions :

  • stepper12_cfg_setup Config Object Initialization function.

    void stepper12_cfg_setup ( stepper12_cfg_t *cfg );
  • stepper12_init Initialization function.

    err_t stepper12_init ( stepper12_t *ctx, stepper12_cfg_t *cfg );
  • stepper12_default_cfg Click Default Configuration function.

    err_t stepper12_default_cfg ( stepper12_t *ctx );

Example key functions :

  • stepper12_set_direction This function sets the motor direction by setting the DIR pin logic state.

    void stepper12_set_direction ( stepper12_t *ctx, uint8_t dir );
  • stepper12_drive_motor This function drives the motor for the specific number of steps at the selected speed.

    void stepper12_drive_motor ( stepper12_t *ctx, uint32_t steps, uint8_t speed );
  • stepper12_set_step_mode This function sets the step mode resolution settings.

    err_t stepper12_set_step_mode ( stepper12_t *ctx, uint8_t mode );

Example Description

This example demonstrates the use of the Stepper 12 Click board by driving the motor in both directions for a desired number of steps.

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. */
    stepper12_cfg_t stepper12_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.
    stepper12_cfg_setup( &stepper12_cfg );
    STEPPER12_MAP_MIKROBUS( stepper12_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == stepper12_init( &stepper12, &stepper12_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( STEPPER12_ERROR == stepper12_default_cfg ( &stepper12 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Drives the motor clockwise for 200 full steps and then counter-clockiwse for 400 quarter steps with 2 seconds delay before changing the direction. All data is being logged on the USB UART where you can track the program flow.

void application_task ( void )
{
    log_printf ( &logger, " Move 200 full steps clockwise \r\n\n" );
    stepper12_set_step_mode ( &stepper12, STEPPER12_MODE_FULL_STEP );
    stepper12_set_direction ( &stepper12, STEPPER12_DIR_CW );
    stepper12_drive_motor ( &stepper12, 200, STEPPER12_SPEED_FAST );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf ( &logger, " Move 400 quarter steps counter-clockwise \r\n\n" );
    stepper12_set_step_mode ( &stepper12, STEPPER12_MODE_QUARTER_STEP );
    stepper12_set_direction ( &stepper12, STEPPER12_DIR_CCW );
    stepper12_drive_motor ( &stepper12, 400, STEPPER12_SPEED_FAST );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

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.Stepper12

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.
