For all Boards

All Boards need a udev rule to be able to program as a regular user (not root). To install these udev rules, follow the steps below:

  1. Download the udev rules: TI udev rules
  2. Open a terminal and execute the following command: sudo mv /71-ti-permissions.rules /etc/udev/rules.d/
  3. If your Linux distribution supports the service command you can active the new rules with sudo service udev restart. If your Linux distribution does not support this command or if you are not able to upload to the LaunchPad with Energia, then restart your computer to activate the rules.
  4. If your board is pulled in, unplug it and plug it back in. Not needed if you rebooted your computer.

Windows Users & Mac OS X Users

Download Energia

The most recent release of Energia can be downloaded from the download page.

Double click the energia-0101EXXXX-macosx.dmg file and drag the Energia application onto the Application folder.

Download and install Java for OS X from Apple.

On OS X 10.8, as Energia 0101E0009 isn’t signed, proceed as follow:

  • First time you use Energia, press `ctrl` and click on Energia, choose `Open` on the menu.
  • A window states Energia isn’t signed and asks for confirmation to launch it: confirm and Energia starts.
  • This procedure isn’t required after.

If a window pop-ups and claims Energia is damaged and can’t be opened. You should move it to the Trash” don’t panic!

The “damaged application” message is a cryptic reminder that Energia isn’t signed and thus not truth-worthy according to Mountain Lion.

Proceed as follow:

  1. Launch Systems Preferences on the Apple menu
  2. Select Security and Privacy
  3. Click on the padlock, type your password and confirm
  4. Select Authorise the apps downloaded from everywhere and confirm
  5. Go back to the folder containing Energia
  6. Ctrl-click on Energia and select Open
  7. If a message asks you to confirm, confirm
  8. Once Energia is running, go back the the Systems Preferences and select the previous setting for Authorise the apps, either Mac App Store or Mac App Store and Identified developers.
  9. Next time you double-click on Energia, the application will be launched normally.

Starting Energia

Double click Energia.exe (Windows users) / Energia.app (Mac OS X users). Energia will start and an empty Sketch window will appear. 

Selecting the Serial Port

Select Serial Port from the Tools menu to view the available serial ports. On windows, they will be listed as COMXXX port and usually a higher number is the LaunchPad com port. On Mac OS X they will be listed as /dev/cu.uart-XXXX. On Mac OS X make sure to select the /dev/cu.uart-XXXX and NOT the /dev/tty.uart-XXX

Selecting the Board

To select the board or rather the msp430 in your LaunchPad, select Board from the Tools menu and choose the board that matched the msp430 in the LaunchPad.

Uploading Your First Blinky Sketch

To compile and upload the Sketch to the LaunchPad click the Upload button.

If all is well then the green LED on your LaunchPad is happily blinking. Congratulations, you have uploaded your first Sketch. Energia includes many more examples to get you started with your electronic project. Need help? The Energia discussion forum is hosted on 43oh.com.
