Stepper 13 click

Stepper 13 Click is a bipolar step motor driver. It features an H-bridge bipolar step motor driver, which supports full-, half-, quarter-, or eighth-step modes. Stepper 13 click also carries a port expander so that the communication can be done with a minimal number of pins, through the mikroBUS™ I2C bus.

Software Support

We provide a library for the Stepper 13 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 13 Click driver.

Example Description

This example demonstrates the use of the Stepper 13 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;
stepper13_cfg_t stepper13_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
stepper13_cfg_setup( &stepper13_cfg );
STEPPER13_MAP_MIKROBUS( stepper13_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == stepper13_init( &stepper13, &stepper13_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( STEPPER13_ERROR == stepper13_default_cfg ( &stepper13 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Drives the motor clockwise for 200 full steps and then counter-clockwise for 200 half

steps and 400 quarter steps with 2 seconds 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" );
Delay_ms ( 2000 );
log_printf ( &logger, " Move 200 half steps counter-clockwise, speed: medium\r\n\n" );
Delay_ms ( 2000 );
log_printf ( &logger, " Move 400 quarter steps counter-clockwise, speed: fast\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.Stepper13

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.
