You didnt specify isolation voltage;
but maybe have a look at

you can use the fact that there is a diode on each pin, so power the device via a resistor; conduction will begin when pin voltage is higher than that of supply
you need to seperate micro from supply incase it does not have protection diode and not try to power the whole power rail with the...

Directly you cannot;
you need an interface; by using a RTL or other interface chip
a non pic (LPC2124 ARM7TDMI-S) example is

look on google; i am sure i have seen someone try/do it.
you can use a transformer to step down to 5V
use a diode to rectify and a capacitor.
when the pic measures the capacitor voltage, when it detects 5V 100VaC is on line
ultrasound+modulator
Dear People,
I am looking for a frequency modulation circuit that operates roughly in the 150kHz range. modulates audio.
It need a means of providing an output of the 150kHz frequency before being modulated. so things like on the fly LC oscilation may not work.
I am...
winpic800 language
From following this post
i gather there is an old version of firmware which is FREE
a new version of firmware which cost 6 or 7
Hardware wise both are the same.
Does anyone have the old firmware and what it support?
Granted this is smaller than usb version of icd2; but no...
