Microchip MCP9808

The Microchip MCP9808 is an I²C device in the LabWired part catalog. Its catalog type is mcp9808. It connects to the MCU over I²C at the default address 0x18. 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 Microchip MCP9808 in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the Microchip MCP9808 (catalog type mcp9808).
  3. Connect VCC and GND to the supply and ground of the board.
  4. Connect SDA and SCL to the I²C data and clock pins of the board.
  5. Run the firmware. It finds the part on the I²C bus at 0x18 and reads and writes it as on hardware.
