Deep sleep #1

Open kadamski opened 4 years ago

kadamski commented 4 years ago

I don't know Bascom to much but looking at the code it seems like you don't use deep sleep and let the AVR core running all the time. With 5V supply, 1.2Mhz clock, this would mean power consumption ~1mA while waiting for an interrupt. If you use deep_sleep and let watchdog (or pin change interrupt) wake the CPU up, this can be reduce to 5uA. See the https://avrhelp.mcselec.com/index.html?config_powermode.htm

If you really want to minimize self drawn current, that's the way to go :)

Thank you for looking into the code and pointing out the way to improve it. I will experiment with it to see how it behaves and hope the added code still fit in this 1 KB MCU ;-). Thank you again for your comment!

Did you ever manage to experiment with this ?
