| | | | 1. yes, you probably killed your analog 5. the analog inputs are very sensitive to over voltage. if your ran more than +5v directly into the input, you probably killed it. next time you're playing with funky voltages, put a 5K resistor in series (...)

| | | | | (...) When I first got my HC11EVB I ran 12V straight into the E port (one of the pins), and was sure I ruined the chip. I called the tech support person at motorola, and he said 12V on a A/D port should be no problem. Sure enough it all still (...) (26 years ago, 20-Jan-99, to lugnet.robotics.handyboard)

| | | | | (...) this isn't right, so i feel the need to correct you. the hc11's analog inputs are sensitive; i have seen many of them destroyed (on a pin-by-pin basis), and voltages above 5v or below 0v are the cause). more accurately, it's not the voltage (...)
