TIDM-TM4C123IOTSTEPPERMOTOR

Design files

Overview

A system example to show how to control a stepper motor via Wi-Fi connectivity. The TM4C123x MCU is integrated with the DRV8833 stepper motor driver to drive the stepper motor in full step, half step and microstep (up to 256) modes. The SimpleLink™ Wi-Fi CC3100 network processor is also integrated into the system to demonstrate the capability of remotely controlling MCU/stepper motor operation via the Internet.

Features
  • The TM4C123 microcontroller uses four PWM pins to control the output of the H bridge drivers in DRV8833 to run the stepper motor in full step, half step and microstep (up to 256) modes.
  • The TM4C123 MCU is also integrated with the SimpleLink CC3100 network processor as a Wi-Fi HTTP server to control the MCU/stepper motor operation remotely via the Internet.
  • Software is designed to work with an EK-TM4C123GXL Launchpad™ kit, SimpleLink CC3100 BoosterPack™ plug-in module and DRV8833 EVM.
  • In addition to stepper motor control, HTML code also enables the user to remotely control the operation of EK-TM4C123GXL LaunchPad including LED toggling, internal temperature reading, and button press recording via a web browser.
  • A UART interface is also created to control the stepper motor.
