#2026 - Port output of 8051: |
Dear friends,
I am using 89C51. When all ports have #0ffh. The output voltage at all pins of Ports 0,1 and 3 is 3+ volts. But output voltage at all pins of port 2 are less than 0.5 volt. Why is that ???? I have to drive a TTL input with port 2. Will it ?? Help............ Babar/ |
