Guide to PROGMEM on ESP8266 and Arduino IDE

Intro

On low memory devices like the arduino and esp8266 you do not want strings to be stored in RAM. This occurs by default on these systems. Declare a string const char * xyz = "this is a string" and it will use up RAM.

The solution on these devices is to allow strings to be stored in read only memory, in Arduino this is the PROGMEM macro. Most of my experience is with the ESP8266 which is a 32bit micros controller. This device stores PROGMEM data in flash. The macro PROGMEM on ESP8266 is simply

#define PROGMEM   ICACHE_RODATA_ATTR

	This file remaps the key bindings of a single user on Mac OS X 10.5 to more
	closely match default behavior on Windows systems. This makes the Command key
	behave like Windows Control key. To use Control instead of Command, either swap
	Control and Command in Apple->System Preferences->Keyboard->Modifier Keys...
	or replace @ with ^ in this file.

	Here is a rough cheatsheet for syntax.
