Which version IDE do I need for ESP8266

Hi, can anyone help? I can't seem to find which version of the IDE I need to programme the ESP8266. I've tried Ver 1.6.1 and couldn't find it in TOOLS/BOARD. I've tried 1.6.5 and still couldn't see it.

I believe you need to got thru the

Tools - Board Manager

to download the non-built-in boards such as the ESP8266

Hi, thanks for the reply. I've checked the tools/board manager and expected to see an option for "Generic ESP8266 board". But it's not there. I've checked Versions 1.6.1 and 1.6.5, but still no luck.

I've found out how to do it. For anyone else wanting to know, check here for the instructions.
