NodeMCU Flasher

NodeMCU flasher is a firmware programmer for NodeMCU DEVKIT V0.9.

You can use it to program NodeMCU DEVKIT or your own ESP8266 board.

You MUST set GPIO0 to LOW before programming, and NodeMCU DEVKIT V0.9 will do it automatically.

This is demo version.

We are working on next version and will use QT framework.

It will be cross platform and open source.
