Stepper 4 Click

Stepper 4 Click is a very versatile bipolar stepping motor driver. It features TB67S269FTG IC, fabricated with the BiCD process, allowing the Click boardâ„¢ 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 :

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.

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;
stepper4_cfg_t stepper4_cfg;
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" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
log_printf ( &logger, " Move 100 steps counter-clockwise \r\n\n" );
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.
