I just got some esp8266 NodeMCU chips, which I want to use for IoT. I understand that these chips are programmed with Lua code. Is this correct?
I found online that I can program these chips with the arduino IDE.
1) Does the arduino code get compiled to Lua?
2) Are there any alternative IDEs for programming these chips?
3) As AVR is used to program Atmel chips on Arduino, is there an equivalent for esp8266s?
What does the 'NodeMCU' in 'esp8266 NodeMCU' mean, as opposed to plain old 'esp8266'.
