#89601 - MCU and multimeters..
Responding to: ???'s previous message
Look a the pin with a multimeter. Is the voltage near Vcc?


Take care though - if you are trying to measure a MCU port pin when the MCU is clocking away happily, you can get very confusing results to say the least ! A scope is the best bet to know what is happening on port pins.

Of course if you are sure that the pin being monitored is not in a loop or some such repeating code, a multimeter CAN give the status of the pin.
