I know this question is so simple and probably stupid that it will enrage some people, but bear with me. :)
When connecting a bench power supply that does 5V@3A, to let's say a P16F88, should I use 25 ohm resistor to bring those 3 Amps down to 200 ma?
According to the p16f88 datasheet:
Maximum current into VDD pin: 200 mA
And by doing so, can I expect 200mA to come out of an output Pin when I turn it on in the pic?
And finally, the reason I ask is that I didnt use a resistor, and I connected the power supply directly to the PIC and after programming it maybe once or twice it no longer works (as in does not return proper ID when programmer asks for it).
I am assuming I fried it and am looking for a solution, thanks.
