hi
well i hav to design a priority based intercom system using microcontroller.....
task is basically that call will be made from one station to another station by pressing a single button...let suppose a button is pressed from station 1 then the signal should be shown on the station 2 which hav been called and m using a blinking LED for indication..this what iz indication side..but now call will i only established when the station 2 will also press the respective button.....if station 2 doesnot press button means LED should be keep on blinking.
now microcontroller iz buzy for blinking loop...let if station 3 pressed button for station 4 same indication signal should go on station 4 n LED should blink...but as microcontroller iz buzy in blinking of first case than how to solve this up.....
is it possible that mmicro controller keep on blinking LED n simultaneously start to operate an other LED,.....
i hav a technique to use two microcontroller one slave n one master slave should scan button pass signal serially to master microcontroller n then master should give signal for LED blinking n switching
plz reply me with solution....
thanks for ur cooperation
