About imp002 POWER_EN

How to control imp002 module POWER_EN ?

Currently, the imp asserts POWER_EN when it needs to start the wifi chip. We intend that in the future, it will also de-assert it when it needs to turn the wifi off (currently, wifi is turned on “lazily”, i.e. when it’s first needed, but then stays on until or unless the imp enters deep sleep). We also intend to expose direct control of POWER_EN to Squirrel, for cases when people need 3v3 power to be up for reasons other than wifi. However, those features aren’t in yet.


I believe de-asserting is implemented now
