TIDCB51A-Driving a Stepper Motor With TM4C MCU Firmware - Wrong Download Code

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

  • Hello Grant,

    We are in the process of correcting it. Thank you for the formal report.

    Hello Grant

    The team is already working on it. I will update the post as soon as I can verify the correct packages get downloaded.

    Hi Grant,

    As Amit has mentioned, we are working to correct the issue noted with the incorrect SW installation in the downloaded zip file. In the meantime, I think you can get a better solution in the software for the WiFi based stepper motor TI design located at this link:

    www.ti.com/.../TIDM-TM4C123IOTSTEPPERMOTOR stepper motor&tisearch=tidesigns

    It is actually the TI design that correlates to the incorrect software installer included in the link for the stepper motor driver code. The primary difference in the motor driver is that the Stepper Motor Driver design uses bit banged GPIOs to drive the stepper motor where the WiFi enabled Stepper Motor uses PWMs. If you strip out the WiFi part of the code, the motor can still be controlled via a UART interface.

    Have a look and see if this is helpful for what you want to do. The best part is that the software included with this TI design actual matches the TI design!! Sorry about the mixup with the other one.

    Thanks and Regards,

    Hello Grant,

    The issue with the download has been corrected and the right software package is now associated with the simple TM4C123 based stepper motor TI design. Please let us know if you see any additional problems or if you have any questions.

    Thanks and Regards,

    Hi Chuck:

    I've downloaded the new code release and verified it is working, thanks!  Per your recommendation above, I'll work on integrating the PWM functionality into this new code release to improve the performance.

    Thanks again,

    Grant
