Stepper Motor Demo Application
4.1
Introduction
As mentioned earlier, the BOOSTXL-DRV8301 Motor Drive BoosterPack has been optimized to work
together with the MSP430G2 Launchpad, MSP-EXP430G2, and MSP430G2553 to provide a complete
stepper motor evaluation platform. With the demo application provided, you can have your stepper motor
up and spinning in minutes. Get started with TI's pre-written stepper control application by following
the steps outlined in
