Energia IDE version (found in Energia > About Energia menu): Energia 1.8.7E21

General description

When I upload a sketch on my launchpad board with MSP430G2452 chip (not tested with 2553), the program runs very slowly. This behaviour is very visible on the blink example, the LED turns ON or OFF after long time (something like 10 seconds). When I upload the same sketch on the the same board with energia 0101E0016, there is no problem, the LED state change each second.

Describe the expected results.

Hi, this is an issue which was fixed already a while ago but as there was no release in the mean time not in the release package so far - but i will go into the next version. If you would like to fix it know just take the wiring.c file out of the repository and replace it with your local version. https://github.com/energia/msp430-lg-core/blob/master/cores/msp430/wiring.c
