i'm sorry but I just run the example and ti's not about any device.

Today i download Energia 1.8 witch is released in 2018. But i found that the sleep() function don't highlight in the editor. And it can't be compilered successfully. (It's same to sleepSeconds() and suspend().) Then i tried Energia 1.6/Enegia-0101E0017 and they also don't support sleep(). It reminds me "error: 'sleep' was not declared in this scope". But i find there are many examples with it on the internet. So, how can i deal with it? please.
