Using output pin to power peripherals; Op-amp, voltage reference, voltage divider....

Did you come to any conclusion about this, I've often wondered (powering external devices from PIC gpio) but never seen anything definitive.

BTW the 1847 has several fixed voltage sources which you could use to measure battery Vdd, no need for divider or subsequent power drain.

Hey George,

Thanks for checking in. I'm still working on the project, it's going VERY slow due to availability of time, and haven't come to a conclusion yet. I'll be sure to check back in when I finish up.

Best regards,
Mark
