... this kind of National ADC questions arise here. In almost all cases the problem was, that the datasheet wasn't fully read or understood. I'm a bit tired of this datasheet reading, help giving and then the OP seeing disappearing without giving any feedback.
So, instead of reading the datasheet for you, my question is: Have you fully read and understood the datasheet of ADC0809? Have you carefully read all the timing plots? Does your code 100%-ly fullfill the timing requirements? Kai Klaas |
