Silent Step 4 click

Silent Step 4 Click is a compact add-on board representing a completely integrated step motor driver solution. This board features the TMC2240, a smart integrated stepper driver from Analog Devices. The driver is based on a 256 micro-steps built-in indexer, two fully integrated H-Bridges, and non-dissipative integrated current sensing (ICS). The two H-Bridges can drive motors of up to 36V and 3A at max.

  • Type : I2C/SPI type

Software Support

We provide a library for the Silent Step 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 Silent Step 4 Click driver.

Example Description

This example demonstrates the use of the Silent Step 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;
silentstep4_cfg_t silentstep4_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
silentstep4_cfg_setup( &silentstep4_cfg );
SILENTSTEP4_MAP_MIKROBUS( silentstep4_cfg, MIKROBUS_1 );
err_t init_flag = silentstep4_init( &silentstep4, &silentstep4_cfg );
if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( SILENTSTEP4_ERROR == silentstep4_default_cfg ( &silentstep4 ) )
{
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 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.SilentStep4

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.
