When using the tap detect, the application note AN4072 in Figure 2 describes a pulse consisting of a positive pulse followed by a negative pulse. Does this result in two taps? If Double Pulse Abort (DPA) is set, will a full-scale positive followed by a full-scale negative result in an abort condition? Should I turn off the DPA instead?
I’m having a hard time determining why I have inconsistent results in my data.
I’ve attached a screen shot that shows an interrupt on the first double-tap, but not after that. I’ve looked at the data in detail, and feel that the following double-taps should fit the qualifications, but I’m wondering if the DPA is preventing the double-tap from working correctly.
