Incorrect ADC values after wake-up

[jucs]

Hi there,

it seems like analogRead() wouldn't work correctly after wake-up from deep sleep mode. This is only the case when the Z-Uno wakes up on its own, the problem does not occur when waking up using the service button / interrupt. The problem persists even when looping "indefinitely" until a correct value is read; a correct value is never read.

Any ideas? Thanks!

Yes, I can confirm it.
Have seen same issue at weekend - was not sure about it, wanted to recheck at first

Made a METER device - is working fine before changing it to sleeping device.
Could not make it working.

It is simple reproducible - so developers can check it.

This week we have found few sever problems with ADC, pins and USB. We will do 2.0.8 very soon. Will be almost no new features, but mostly stability fixes.
