#145447 - One more doubt Responding to: ???'s previous message |
Hi friends,
I really thank you for your valuable suggestions given before. I have one more doubt, which is arising when I interface at89c52 with ADC 0804. I could read all the output pins to high irrespective of the input. Whether the input is low or high, output does not changes!! Can anyone guide me in this issue? |
