Problem with loading simple code

By Gold
- Thu Jun 27, 2019 2:57 pm #82937 Hi, I've just bought a NodeMCU v2 and I'm trying to load the simple code in the pictures but I always receive one of the two errors. What can I do to fix them?

  • Remove NodeMCU from development PC's USB port
  • Install the correct firmware for the used on-board USB -> UART convertor (either a CH340g or a CP2102).
  • Connect USB to development PC
  • Make a note of the assigned COM-port (if not shown, or the dialogbox went away too fast, look for the number in the "Device Manager" under "Ports (COM & LPT)")
  • Start up the Arduino IDE and under "Tools" select:
    • Board: NodeMCU (any version will work)
    • Port: <The COM-port you just made a note of>
  • It should work now
