Can anyone tell me how to connect reed switch to 89c51? I directly connected the 2 ends of the swtch to vcc and ground. but the switch is not functioning properly.. on application of 5 volts..as i bring magnet near to it..internal mechanism of the swtch gets short... when i remove the magnet, it remains short, doesnt go to its original position, what to do?
Check the Keil manuals. Search for "reed-switch". If you don't find it, it's likely not going to be a Keil related problem and therefore not a relevant question for the Keil forum.
