How to: power consumption of intermittent, spikey projects
The battery will be a primary cell, probably Lithium Thionyl Chloride. I'm not over concerned about self discharge. Ten units? I have two. The client has the third, and more...

Am I reading this  correctly, you have a 10 mSec duration ISR running every 5 Seconds?   I sometimes have an LED that I flash for 10mS every 5 seconds.   To...

How to: power consumption of intermittent, spikey projects
I have always used the same approach, i.e. measure the sleep current, measure the transmit current, do a bit of arithmetic. This one's a bit busier, though. There's an interrupt...

Resurrecting an old thread here, but it's a problem I have recently encountered again with a LoraWan node that idles at tens of uA, but peaks at around 100mA. The Dave Jones...
