ESP8266.net — The Internet of Things with ESP8266. Getting Started With The ESP8266 WIFI Microcontroller. By Stephen Stebbing2015-03-07 02:04:05 ESP8266 is a powerful, WIFI enabled, 32-bit microcontroller which is available for just a few dollars.
Given its versatility, it is not surprising that it is becoming very popular for InternetOfThings-type application, and will likely continue to do so. It has a strong and helpful community of users behind it, and new applications and tools are being developed very rapidly. The difficulty that I had in getting started was that there was no central source for the required information; I ended up spending quite some time searching, trolling through forums, reading source code and various other documentation in order to get up and running, and to glean some idea about how things work, and what is going on in general.
Anwyay, here I will document the various steps that I took to: Wire up the hardware Test the module with AT commands Install the C SDK Flash the device Set up for development with NodeMCU Lua environment CH_PD is the chip enable line. 3.1. Getting Started with NodeMCU Board Powered by ESP8266 WiSoC. Since ESP8266 is now so popular, I’ve recently bought a NodeMCU board to try it.
I selected this board because the latest version of the board is breadboard-friendly, integrates a USB to serial chip, and it can be powered by a simple USB to micro USB cable. I also noticed a ESP8266 tutorial with NodeMCU firmware by SwitchDoc Labs the other day (using ESP-12 and Adafruit Huzzah), which I applied to my NodeMCU board, but since I encountered a few issues, I decided to report my findings, and write my own little getting started guide to switch on/off LED and GPIOs using a web interface. NodeMCU v0.9 and NodeMCU v1.0. How to Directly Program an Inexpensive ESP8266 WiFi Module. The ESP8266 is the answer to “I want something with Wifi.”
Surprisingly, there are a number of engineers and hobbyists who have not heard of this chip or have heard of it but don’t really understand what it is. It’s basically the answer to everything IoT to so many engineering problems that have plagued the hobbyist and commercial world alike. The chip is a processor with integrated RAM, some ROM, and a WiFi radio, and the only external components you will need are 4 capacitors, a crystal and an external flash!
It’s CHEAP, like $4/ea cheap! Or $5 if you want it on a nice, convenient carrier board that includes all these components. One place thing that more people need to know about is how to program directly for this chip. Know thy Hardware First off, some background. The processor by default runs at 80 MHz but can go up to 160 MHz, it has ~80kB DRAM (Data RAM), and ~35kB of high speed IRAM (Instruction RAM).4 Yes, that means it uses a Harvard architecture.
