where do I "kick-start" the regulator?
Vbat starts at 6V. The regulator is fixed at 3.3V, so the Atmel is running at that voltage (or at max that voltage.) At 8MHz, the thing ran solidly for 15 hours before it finally "got stuck". Measuring voltage then, it was measuring 3.1V coming straight off of the batteries, regulator was providing anywhere between 3.0 and 2.7V ... which is about where things start to go wonky and I'm perfectly okay with that. At the first signs of the Atmel quitting (which it will), it just needs to shut stuff off.So, looking at your schematic, will the above tolerances work for the FETs? And also, where do I "kick-start" the regulator? As in, where would the momentary switch get wired to so I can provide temporary power to the ENable pin of the regulator till the Atmel starts running and brings its pin HIGH to maintain the regulator?
