Low Power

I am trying to get the current drain down on my own 'bare metal' LPC1768 board,

So far using DeepPowerDown() I can get it down to 8.2 mA, But I need much lower, less than 0.2 mA.

I have found: Link

Which is very good so far,

Also how do I wake up from sleep/power down modes, Button, a 500 mS tick would be nice

Cheers

Hi Ceri

Did you get any further with this? Reading through the uP datasheet deep power down mode could get current draw down to 200 nA!

It is unclear what the wakeup times are however?

It is still on a list of stuff to do,

Sorry to dissapoint.

but if you find more joy then please forward.
