Running the Java Keytool on Mac

Locate your java home directory by executing in Termal

/usr/libexec/java_home

This will return the full path to your java home directory on your Mac. Change into that directory and then you will be able to run the java keytool from there.

Here is a log of what I ran in Terminal on my Mac:

$ /usr/libexec/java_home
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
$ cd /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
$ keytool

Connecting ESPDUINO (ESP-13) to Arduino IDE

https://github.com/esp8266/Arduino was the most helpful place to start. You need to

  • open the Arduino IDE
  • Open ‘Preferences’ menu under ‘File’
  • Add the url http://arduino.esp8266.com/stable/package_esp8266com_index.json to the ‘Additional Boards Manager URLs’ input box
  • click ‘OK’
  • open menus ‘Tools’ -> ‘Board’ -> ‘Boards Manager’
  • find the esp8266 by searching in search filter input
  • Click the esp8266 and click install

You should then be able to connect to and upload sketches to the espduino board.
