#101188 - AT89c2051 port pin remains latched |
in my application o/p of comparator is given to p1.3 through a 10k resistor and 4.7v zener as o/p of comparator is 12v.
when comp o/p is low the p1.3 shows 0v, when comp o/p is high the p1.3 goes to 4.7v. but comp o/p coming back to 0v leaves the p1.3 pin at 2.5V controller i used is AT89c2051 can any one guide me |
