#107956 - PLS HELP Responding to: ???'s previous message |
I AM USING PHILIPS P89C51RD2 MICROCONTROLLER.I AM WORKING ON A FIRE ALARM CONTROL PANEL..WHENEVER THERE IS FIRE OR SOME SHORT CIRCUIT IN THE DETECTOR THE EVENT SHOULD BE LOGGED ,THAT IS I SHOULD BE ABLE TO STORE SOME DATA BYTE IN FLASH MEMORY,SO THAT EVEN WHEN THE POWER IS SWITCHED OFF THIS INFORMATION STILL REMAINS IN THE INBUILT FLASH WHICH CAN BE LATER ACCESSED.
KINDLY TELL ME IF THIS IS POSSIBLE USING PHILIPS 89C51RD2 MICROCONTROLLER |
