DRV8825 Stepper Driver

The DRV8825 Stepper Driver is a board I/O module in the LabWired part catalog. Its catalog type is drv8825. It connects to the MCU over GPIO. The catalog gives a supply range of 8.2–45 V. It has 10 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.

How to simulate the DRV8825 Stepper Driver in LabWired

Open the Playground at app.labwired.com and place an MCU board.
Add the DRV8825 Stepper Driver (catalog type drv8825).
Connect VMOT and GND to the supply and ground of the board. Use a supply inside the catalog range of 8.2–45 V.
Connect STEP, DIR, EN, M0, M1, M2, RESET and SLEEP to free GPIO pins.
Run the firmware. It drives and reads the pins of the part, and the device model responds on those pins.
