Stepper 24 Click

Stepper 24 Click is a compact add-on board designed to drive small stepping motors in consumer electronics and industrial equipment applications. This board features the TB67S589FTG, 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 2.7A 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.

Click library

• Author : Stefan Filipovic
• Date : Jun 2024.
• Type : I2C type

Software Support

We provide a library for the Stepper 24 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 24 Click driver.

Standard key functions :

• stepper24_cfg_setup Config Object Initialization function.

void stepper24_cfg_setup ( stepper24_cfg_t *cfg );

• stepper24_init Initialization function.

err_t stepper24_init ( stepper24_t *ctx, stepper24_cfg_t *cfg );

• stepper24_default_cfg Click Default Configuration function.

err_t stepper24_default_cfg ( stepper24_t *ctx );

Example key functions :

• stepper24_set_direction This function sets the motor direction by setting the DIR pin logic state.

void stepper24_set_direction ( stepper24_t *ctx, uint8_t dir );

• stepper24_set_step_mode This function sets the step mode resolution settings.

err_t stepper24_set_step_mode ( stepper24_t *ctx, uint8_t mode );

• stepper24_drive_motor This function drives the motor for the specific number of steps at the selected speed.

void stepper24_drive_motor ( stepper24_t *ctx, uint32_t steps, uint8_t speed );

Example Description

This example demonstrates the use of the Stepper 24 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. */
    stepper24_cfg_t stepper24_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.
    stepper24_cfg_setup( &stepper24_cfg );
    STEPPER24_MAP_MIKROBUS( stepper24_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == stepper24_init( &stepper24, &stepper24_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( STEPPER24_ERROR == stepper24_default_cfg ( &stepper24 ) )
    {
        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 200 half steps and 400 quarter steps with a 1 second delay on driving mode change. 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, speed: slow\r\n\n" );
    stepper24_set_direction ( &stepper24, STEPPER24_DIR_CW );
    stepper24_set_step_mode ( &stepper24, STEPPER24_MODE_FULL_STEP );
    stepper24_drive_motor ( &stepper24, 200, STEPPER24_SPEED_SLOW );
    Delay_ms ( 1000 );

    log_printf ( &logger, " Move 200 half steps counter-clockwise, speed: medium\r\n\n" );
    stepper24_set_direction ( &stepper24, STEPPER24_DIR_CCW );
    stepper24_set_step_mode ( &stepper24, STEPPER24_MODE_HALF_STEP_TYPE_A );
    stepper24_drive_motor ( &stepper24, 200, STEPPER24_SPEED_MEDIUM );
    Delay_ms ( 1000 );

    log_printf ( &logger, " Move 400 quarter steps counter-clockwise, speed: fast\r\n\n" );
    stepper24_set_direction ( &stepper24, STEPPER24_DIR_CCW );
    stepper24_set_step_mode ( &stepper24, STEPPER24_MODE_QUARTER_STEP );
    stepper24_drive_motor ( &stepper24, 400, STEPPER24_SPEED_FAST );
    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.Stepper24

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.
