datalog module

newtothis

The datalog module is triggered by the first input crossing the "trig value." So once the buffer is full with logged values, does it "re-log" data (or behave in circular fashion) when the first input crosses the trig value low to high again? Want to confirm whether the module will stop logging data if the buffer is filled and the first input remains above the trig value.

Hi Newtothis,

Yup DLOG will "re-log" once it is full and it has appropriate trigger condition on input. If the buffer is full, the DLOG will not start with "re-loging" until it next trigger condition. It is like a scope in Normal triggering mode (not Auto and not single-shot)

Hi Mitja,

A simlar issue stumbles me. How to trigger the Datalog interrupt of C2000 DSP? Could you enlighten the clue?

Thanks

Hi Adam,

channel 1 acts as a trigger, so value sampled by channel 1 should cross (with positive slope) the trigger value.
