software failing problems
i have made different programes for moving display ffor words made from ledsand
other to control motors from sensor inputs and by inputing logic high through push
buttons for stopping and moving the motors. I am using 89c51and 2003and relays for contol.
for motors ihave used snubbers and isolated supply for mc and relays . i have noticed that after around 30 minutes(random till 1 hr) of operation in both cases the mc software fails and does not respond to any instructions!!! . i am missing something as a programer that is to be taken into account??? can someone guide
