Stepper 20 click

Stepper 20 Click is a compact add-on board that contains a bipolar stepper motor driver. This board features the TB67S580FNG, a two-phase bipolar stepping motor driver from Toshiba Semiconductor. Fabricated with the BiCD process, it supports a PWM constant-current control drive and steps resolution from full to 1/32 for less motor noise and smoother control. It has a wide operating voltage range of 8.2V to 44V with a maximum output current capacity of 1.28A, decay modes selection function, protection, and several anomaly detection indicators.

  • Date : Feb 2023.
  • Type : I2C type

Software Support

We provide a library for the Stepper 20 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 20 Click driver.

Standard key functions :

Example Description

This example demonstrates the use of the Stepper 20 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;
stepper20_cfg_t stepper20_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
stepper20_cfg_setup( &stepper20_cfg );
STEPPER20_MAP_MIKROBUS( stepper20_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == stepper20_init( &stepper20, &stepper20_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( STEPPER20_ERROR == stepper20_default_cfg ( &stepper20 ) )
{
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" );
Delay_ms ( 2000 );
log_printf ( &logger, " Move 400 quarter steps counter-clockwise \r\n\n" );
Delay_ms ( 2000 );
}

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.Stepper20

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.
