I'm not tryin to offend anybody, but this is a legitimate question.
i got a DIO pin with rated capacity of 40mA, and i'm tryin to figure out if it's kosher to connect a 1uF cap straight from pin to ground and safely charge it without a series resistor.
i know mathematically and mechanically that there is a certain wattage limit, or more precisely, a certain "surge capacitance" limit, that it can comfortably handle if it only does it once on power up. And if it was a generally useful thing to know, then there would exist a standard measurement protocol and a clearly defined rating for digital output pins.
But it's not and there ain't. So does anyone have any experience with this?
