Multi Stepper Click is a compact add-on board that contains a bipolar stepper motor driver. This board features the TB67S269FTG, CLOCK-in controlled bipolar stepping motor driver from Toshiba Semiconductor. It supports a PWM constant-current control drive and allows from full-step up to 1/32 steps resolution for less motor noise and smoother control. It has a wide operating voltage range of 10V to 47V with an output current capacity of 1.4A in addition to several built-in error detection circuits.

We provide a library for the Multi Stepper TB67S269 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.
This library contains API for Multi Stepper TB67S269 Click driver.
multisteppertb67s269_cfg_setup
Config Object Initialization function.
void multisteppertb67s269_cfg_setup ( multisteppertb67s269_cfg_t *cfg );
multisteppertb67s269_init
Initialization function.
err_t multisteppertb67s269_init ( multisteppertb67s269_t *ctx, multisteppertb67s269_cfg_t *cfg );
multisteppertb67s269_default_cfg
Click Default Configuration function.
err_t multisteppertb67s269_default_cfg ( multisteppertb67s269_t *ctx );
multisteppertb67s269_set_step_mode
This function sets the step mode resolution settings.
err_t multisteppertb67s269_set_step_mode ( multisteppertb67s269_t *ctx, uint8_t mode );
multisteppertb67s269_drive_motor
This function drives the motor for the specific number of steps at the selected speed.
void multisteppertb67s269_drive_motor ( multisteppertb67s269_t *ctx, uint32_t steps, uint8_t speed );
multisteppertb67s269_set_direction
This function sets the motor direction by setting the AN pin logic state.
void multisteppertb67s269_set_direction ( multisteppertb67s269_t *ctx, uint8_t dir );
This example demonstrates the use of the Multi Stepper TB67S269 click board by driving the motor in both directions for a desired number of steps.
The demo application is composed of two sections :
Initializes the driver and performs the click default configuration.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
multisteppertb67s269_cfg_t multisteppertb67s269_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.
multisteppertb67s269_cfg_setup( &multisteppertb67s269_cfg );
MULTISTEPPERTB67S269_MAP_MIKROBUS( multisteppertb67s269_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == multisteppertb67s269_init( &multisteppertb67s269, &multisteppertb67s269_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( MULTISTEPPERTB67S269_ERROR == multisteppertb67s269_default_cfg ( &multisteppertb67s269 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " 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" );
multisteppertb67s269_set_direction ( &multisteppertb67s269, MULTISTEPPERTB67S269_DIR_CW );
multisteppertb67s269_drive_motor ( &multisteppertb67s269, 200, MULTISTEPPERTB67S269_SPEED_FAST );
Delay_ms ( 2000 );
log_printf ( &logger, " Move 100 steps counter-clockwise \r\n\n" );
multisteppertb67s269_set_direction ( &multisteppertb67s269, MULTISTEPPERTB67S269_DIR_CCW );
multisteppertb67s269_drive_motor ( &multisteppertb67s269, 100, MULTISTEPPERTB67S269_SPEED_FAST );
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.

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.
