UART device

XY-MD02

The XY-MD02 is a UART device in the LabWired part catalog. Its catalog type is xy-md02. It connects to the MCU over UART. The catalog gives a supply range of 5–30 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.

From the catalog: XY-MD02 Modbus RTU slave modelled from the manufacturer manual: input registers 0x0001/0x0002 (temperature, humidity), holding registers 0x0101..0x0104 (address, baud, temperature and humidity correction), functions 03/04/06/10, CRC-16, 3.5-character framing, standard exceptions 01-03. No text protocol (READ, AUTO, BR:, TC:), no parity.

How to simulate the XY-MD02 in LabWired

Open the Playground at app.labwired.com and place an MCU board.
Add the XY-MD02 (catalog type xy-md02).
Connect GND and VCC to the supply and ground of the board. Use a supply inside the catalog range of 5–30 V.
Connect B and A as your circuit needs.
Run the firmware. It sends and receives bytes on the simulated UART as on hardware.
