#102155 - Why using an interrupt? Responding to: ???'s previous message |
Suresh said:
i am using p3.2 of AT89c51 to receive a falling edge signal using a push button switch.Hence an interrupt0 edge flag is set in IE0. Is there really a need to use an interrupt routine to serve the push button? Is your main program loop so long lasting that a periodically reading of P3.2 (polling) does not do the job? Kai |
