Stepper 22 Click is a compact add-on board designed for precise motion control of bipolar stepper motors and brushed DC motors. This board features the DRV8711, a bipolar stepper motor gate driver from Texas Instruments, which uses external N-channel MOSFETs to drive motors with up to 5A of output current. The board features a wide range of microstepping options from full-step to 1/256-step, adaptive blanking time, and various current decay modes, ensuring smooth and accurate motor operation. Control is achieved via a standard SPI interface and STEP/DIR inputs, with additional management through an onboard I2C-configurable GPIO expander.
We provide a library for the Stepper 22 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 Stepper 22 Click driver.
stepper22_cfg_setup
Config Object Initialization function. stepper22_init
Initialization function. stepper22_default_cfg
Click Default Configuration function. stepper22_set_direction
This function sets the motor direction by setting the DIR pin logic state. stepper22_set_step_mode
This function sets the step mode resolution settings. stepper22_drive_motor
This function drives the motor for the specific number of steps at the selected speed. This example demonstrates the use of the Stepper 22 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.
Drives the motor clockwise for 200 full steps and then counter-clockiwse for 200 half
steps and 400 quarter steps with a 1 second delay on driving mode change. All data is being logged on the USB UART where you can track the program flow.
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.
