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.
