Figure 5. DRV8824-25 GUI
The DRV8824-25 has an updated GUI that contains all the necessary control signals for driving a bipolar
stepper. Important aspects to control are enablement, direction of rotation, speed, number of steps,
reference voltage (for maximum current) and degrees of microstepping.
Figure 6. DRV8841-43 Tab
The DRV8841-43 tab is very similar to the DRV8802-12-13-14 tab, except correct naming conventions
have been followed to showcase the AINx pins (instead of PHASE and ENABLE). In this tab, the four INx
signals have a respective PWM slider in order to provide speed control per H Bridge on both directions
per H Bridge.
