I know a lot of people who bought the Texas Instruments MSP430 LaunchPad development kit but never really got into it. I’m one of them; the $4.30 purchase price was compelling, but the requirement to install a huge proprietary IDE (with its own embedded C dialect) was just too much.
For this reason, Energia is great. It’s a fork of the Wiring/Arduino development environment for the MSP430. Looks just like Arduino, but quite red:
The basics of the language are the same, although the pin names and functions are different from the Arduino. The basic board also has a red and a green LED, a user button, and the obligatory reset button.
