When I download the above mentioned zip file (TIDCB51A) and extract the files they are the same ones found for the IOT Stepper Motor Design (i.e. TIDCBI8A-Microstepping Stepper Motor Control with MCU and Wi-Fi Software).
Can you please put the correct code on the website for the TIDM-TM4C123STEPPERMOTOR which does not include the Wifi functionality.
Thanks,
Grant
