New Product – We are running #Lua on #ESP8266 #NodeMcu
NodeMcu is an dev board enabling you use Lua script on ESP8266 on a higher Software Abstract Layer. Featuring an open-source firmware, it is also equipped with a development toolchains helps you burn the firmware, download the codes. Currently it’s friendly to Windows system, the creators are developing the cross platform dev kits right now.
It will be in stock on 20th, only at seeedstudio.
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:
[bash]
ls /dev | grep tty | head
[/bash]
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.
Here’s a listed feature of the programming interfaces for your reference.
- IO
- PWM
- Wifi
- HTTP Server
- Read Sensor
The product will be in stock in 1 week, the team is developing the cross platform. Are you ready?
About Author
So I got one of these – yeah!
after downloading the OSX driver, I was unable to detect device. Then I came across this in Stack Exchange which fixed the issue: http://arduino.stackexchange.com/questions/3700/rename-device-name-ch340-usb-to-serial-mac-os
….
A note for those on Yosemite you seem to need to run this command in the Terminal and then restart the computer to get it to work.
sudo nvram boot-args=”kext-dev-mode=1″
Any news on availability?
