Problem with loading simple code
Posted: Thu Jun 27, 2019 2:57 pmHi, 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
