Hello,
The Blink example works 16 times slower than expected on EXP430G2 rev.1.3 with MSP430G2452. Also enableXtal() gives up after >30 seconds. Perhaps some divider not properly adjusted.
I wanted to play with the kids and Energia/Launchpad, but no luck :( Usually, I use CCS for MSP430 development, and I'm not quite familiar with Energia and the init sequence.
Energia 1.8.7E21 (Linux 64), Launchpad EXP430G2 rev 1.3, MSP430G2452, no XTAL
