TMC2209 Stepper

The TMC2209 Stepper is a board I/O module in the LabWired part catalog. Its catalog type is tmc2209. It connects to the MCU over GPIO. The catalog gives a supply range of 4.75–29 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 TMC2209 Stepper in LabWired

Open the Playground at app.labwired.com and place an MCU board.
Add the TMC2209 Stepper (catalog type tmc2209).
Connect VM, GND and VIO to the supply and ground of the board. Use a supply inside the catalog range of 4.75–29 V.
Cross the UART lines: connect PDN_UART to the RX pin of the board.
Connect STEP, DIR, EN, MS1, MS2 and DIAG to free GPIO pins.
Run the firmware. It drives and reads the pins of the part, and the device model responds on those pins.
