#109233 - Polled means...... Responding to: ???'s previous message |
In this case that there is a loop in the program which repeatedly checks the state of the inputs and does something when they change so the loop is constantly polling the inputs as oposed to an interrupt driven routine which uses a special input which triggers an internal interrupt to tell the processor when an input has changed state and the processor then does something.
polled routines are in my humble opinion a pain in the bum for anything but the simplest applications. |
