Here’s a short and dirty guide for mac users to getting started.
Install the driver
NodeMcu uses a USB 2 Serial called CH340, you have to download the driver, install the package as you used to do on Mac.
After the installation, you can test the serial by filtering using simple bash:
ls /dev | grep tty | head
In this picture the tty.wchusbserialfa130 is the right one.
Connect the board
I’m using iterm2 on the mac as terminal simulator, using screen command to connect the serial.
After you logging successful, you will find the Lua interpreter.
The init.lua file does not exist by default, you have to download the codes with the Dev kits or using the code (file.writeline). If you are using Mac, you will meet the gap downloading the code , not supported for Mac right now.
