Sorry no one every got to review this. It's now outdated, these functions are legacy in the IDF. Also, the functionality should be added to the So I'll close this PR. |

The esp32 can enter deep sleep and use really little current. For example on the tinypico board I measured a current of 24 uA in deep sleep.
The esp32 also provides a touch sensor module which can be used to wake-up from deep sleep. However this module uses about 2 mA of current to do the touch detection and (by default) does it for about 4ms at 37 Hz.
This means that all these efforts to use really little power will be ruined by the touch sensor using 100 times the sleep power roughly 15% of the time.
The good news it that Espressif provides a way to customize those timings and depending on the application, the power consumption of the touch sensor can be greatly reduced.
This patch simply exposes this functionality in python.
