Multi Stepper TB62269 click

Multi Stepper Click is a compact add-on board that contains a bipolar stepper motor driver. This board features the TB62269FTG, PWM method 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 38V with an output current capacity of 1.2A in addition to several built-in error detection circuits.

Software Support

We provide a library for the Multi Stepper TB62269 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 Multi Stepper TB62269 Click driver.

Example Description

This example demonstrates the use of the Multi Stepper TB62269 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;
multisteppertb62269_cfg_t multisteppertb62269_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
multisteppertb62269_cfg_setup( &multisteppertb62269_cfg );
MULTISTEPPERTB62269_MAP_MIKROBUS( multisteppertb62269_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == multisteppertb62269_init( &multisteppertb62269, &multisteppertb62269_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
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 ( 2000 );
log_printf ( &logger, " Move 100 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.MultiStepperTB62269

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.
