Hello friends this time I have developed a IC 555 based controller to control stepper motor This controller can control speed as well as direction of stepper motor. This small PCB based controller is ...

When [compiling your build](Compile-your-build) add the following to `user_config_override.h`: ```c++ #ifndef USE_A4988_STEPPER #define USE_A4988_STEPPER // A4988/DRV8825 stepper motor (+10k5 code) ...

Stepper motors divide a full rotation into hundreds of discrete steps, which makes them ideal to precisely control movements, be it in cars, robots, 3D printers or CNC machines. Most stepper ...

We applied DRV8434AEVM using GUI to operate the customer's motor. Customer is using 2phase 4wire motor. And we have some questions. 1. How can we measure the back-emf when motor was operating? 2. We ...
