Using Arduino IDE

While the Feather HUZZAH ESP8266 comes pre-programmed with NodeMCU's Lua interpretter, you don't have to use

it! Instead, you can use the Arduino IDE which may be more familar. This will write directly to the firmware, erasing the

NodeMCU firmware, so if you want to go back to Lua, use the flasher to re-install it (https://adafru.it/f1O)

In order to upload code to the ESP8266 and use the serial console, connect any data-capable micro USB cable to the

Feather HUZZAH and the other side to your computer's USB port.

Don't forget you will also need to install the SiLabs CP2104 Driver:

On Mac OS 10.13 and higher, in addition to installing, you will have to give the CP2104 kernel driver permission to load.

You can find out if you need to give additional permission by visiting your Security & Privacy settings system

preferences screen after installing and looking for the message that says, 'System software from developer "SiLabs"

was blocked from loading', like in the picture below.
