Esp8266
Posted: Fri Jul 22, 2016 12:45 amWhy not I figured I would include some info about the esp8266 itself and where everything is located in address space I will warn this was copy/paste info. But good to have in the hardware section.
Kind of useful if someone were going to try and disassemble the thing or create an emulator or simulator that would allow you to see instructions being made and some of this allow user input in cmd/resp format so you can see what is happening at machine level or even pause things or slow them down etc I've seen this before but this is normally more of an assembly based thing while not related to basic directly it is related indirectly so might be useful for those on the search.
