I googled and found around 5, all for windows and linux but not mac. Navigate to the directory in which bin file is present and run the following command (replace the COM port with the one you found in previous step, and bin file name should the one you downloaded) esptool.

Using a cheap ESP8266 as an interface, enables a target lacking a network interface (e. I bought a Nodemcu ESP8266 a while ago and I wasn't using it, so when I heard about the micropython project, I got interested. The first release of Micropython for ESP8266 was delivered a couple of weeks ago. Pulse Width Modulation. My idea is to use the nice ESP8266 and do everything in python (micropython). io from the ESP8266.

MicroPython on ESP8266 This tutorial features topics on How to get started on MicroPython. Once we have the "Pin" function imported, we use it to create a pin object, with the first parameter telling it to use gpio2 , and the second parameter telling it to switch it into output mode. The board also expose a very interesting UEXT port but we will cover it later on. In this post I'd like to walk through the process of getting a NodeMCU ESP8266 device flashed and up and running with MicroPython. All ESP8266 boards running MicroPython.
