Stepper 4 Click is a very versatile bipolar stepping motor driver. It features TB67S269FTG IC, fabricated with the BiCD process, allowing the Click board™ to handle significant voltage and current levels up to 35V and 1.2A. This IC has the integrated translator section, used to simplify the control: using simple step control inputs from the host MCU, the stepper motor can be driven in both directions, with the predetermined step sizes from the full step, up to 1/32 step.

Click library

  • Author : Stefan Filipovic
  • Date : Feb 2024.
  • Type : GPIO type

Software Support

We provide a library for the Stepper 4 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 4 Click driver.

Standard key functions :

  • stepper4_cfg_setup Config Object Initialization function.

    void stepper4_cfg_setup ( stepper4_cfg_t *cfg );
  • stepper4_init Initialization function.

    err_t stepper4_init ( stepper4_t *ctx, stepper4_cfg_t *cfg );
  • stepper4_default_cfg Click Default Configuration function.

    void stepper4_default_cfg ( stepper4_t *ctx );

Example key functions :

  • stepper4_set_direction This function sets the motor direction by setting the DIR pin logic state.

    void stepper4_set_direction ( stepper4_t *ctx, uint8_t dir );
  • stepper4_drive_motor This function drives the motor for the specific number of steps at the selected speed.

    void stepper4_drive_motor ( stepper4_t *ctx, uint32_t steps, uint8_t speed );
  • stepper4_reset_device This function resets the device by toggling the RST pin.

    void stepper4_reset_device ( stepper4_t *ctx );

Example Description

This example demonstrates the use of the Stepper 4 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. */
    stepper4_cfg_t stepper4_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.
    stepper4_cfg_setup( &stepper4_cfg );
    STEPPER4_MAP_MIKROBUS( stepper4_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == stepper4_init( &stepper4, &stepper4_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    stepper4_default_cfg ( &stepper4 );

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

Application Task

Drives the motor clockwise for 200 steps and then counter-clockiwse for 100 steps with 2 seconds delay before changing the direction. Each step will be logged on the USB UART where you can track the program flow.

void application_task ( void )
{
    log_printf ( &logger, " Move 200 steps clockwise \r\n\n" );
    stepper4_set_direction ( &stepper4, STEPPER4_DIR_CW );
    stepper4_drive_motor ( &stepper4, 200, STEPPER4_SPEED_FAST );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf ( &logger, " Move 100 steps counter-clockwise \r\n\n" );
    stepper4_set_direction ( &stepper4, STEPPER4_DIR_CCW );
    stepper4_drive_motor ( &stepper4, 100, STEPPER4_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.Stepper4

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.

ADC 20 Click

0

ADC 20 Click is a compact add-on board with a high-performance data converter. This board features the TLA2518, an SPI-configurable eight-channel 12-bit successive approximation register analog-to-digital converter (SAR ADC) from Texas Instruments. The TLA2518 has an internal oscillator for the ADC conversion and supports averaging multiple data samples with a single conversion start. Also, the built-in programmable averaging filters help reduce noise from the analog inputs and reduce the number of data samples required to be read by the host MCU. All eight channels can be used as analog inputs, with the addition that the four channels can be used as digital inputs or digital outputs.

ADC 15 Click is a compact add-on board that contains a high-performance data converter. This board features the ADS131M02, a two-channel, simultaneously sampling, 24-bit, delta-sigma (ΔΣ), analog-to-digital converter from Texas Instruments. The ADC inputs can be independently configured via serial peripheral interface depending on the sensor input. A low noise, programmable gain amplifier (PGA) provides gains ranging from 1 to 128 to amplify low-level signals.
