TM1637 7-Segment (4-digit)

The TM1637 7-Segment (4-digit) is a board I/O module in the LabWired part catalog. Its catalog type is tm1637-7seg. It connects to the MCU over GPIO. The catalog gives a supply range of 3–5.5 V. It has 4 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 TM1637 7-Segment (4-digit) in LabWired

Open the Playground at app.labwired.com and place an MCU board.
Add the TM1637 7-Segment (4-digit) (catalog type tm1637-7seg).
Connect GND and VCC to the supply and ground of the board. Use a supply inside the catalog range of 3–5.5 V.
Connect CLK and DIO to free GPIO pins.
Run the firmware. It drives and reads the pins of the part, and the device model responds on those pins.
