A quick tutoral guide to setting up a Linux development environment for the ESP8266 WIFI enabled microcontroller. Intended for someone who might have just taken delivery of their first module and is wonder where to start. Covers hardware, firmware, C SDK, and NodeMCU Lua.

Very Helpful Stuff Bro,..Thankyou Very Much.

I've been meaning to get one of these chips to play with! I'd like to do webserver (or ftp server) that can be used for updating the programming file of an arduino! In general once you have the compiler/toolchain setup (or download a virtual machine image), can you flash a small tcp/ip stack (ex. uip or lwip) onto the chip for a totally custom internet solution? Or is the idea that Espressif's library has a tcp/ip stack that can do it all, and so no tcp/ip programming is required? I've used ARMs in the past, is the architecture of the 80Mhz Tensilica Xtensa 32bit processor remotely similar to an ARM? Either in the architecture ARM7,8 etc, or in the instruction set ARM7v6, v7-M?

Hello Ben,

I can't answer regarding the similiarities with ARM as I have little to do with either architecture. Espressif's SDK does include the lwip.a library, so persumably their TCP/IP API wrappers this. You might consider the FreeRTOS port to ESP8266; it gives a more Unix-like API. Re the Aurdino - there is a open source project called 'Absolutely Transparent TCP/IP to Serial Bridge' which allows for just this.

Cheers, Steve.
