Make sure your voltage dividers, ADC inputs, etc don't add micromps of loading, or it will...
How to: power consumption of intermittent, spikey projects Yes, I have a digital scope. I have used it before But it's a dynamic range problem again. Also, my digital scope won't let me sample at a fast enough speed for several hours....
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...

How to: power consumption of intermittent, spikey projects 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...

acc dec stepper, why it is so difficult ? I used to write code for fruit machines/slot machines. Amongst other things.
Getting the reels to start and stop in a desirable fashion was very, very tricky. Probably because the...

Implementing a 32-bit input capture timer I am probably barking up the wrong tree. The thing I had problems with was a slightly different scenario, whereby I was using the external clock input to a timer to count pulses...

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...

All interesting, but any insight on charging my supercap?
