pptrig

pptrig is a tool for troubleshooting the triggering.

Command line switches for setting the trigger:

-trig_int: use internal trigger signals (generated using a PIO under software control)
-trig_ext: use external trigger signals
-trig_misc: use trigger signals from on-board interfaces (pushbuttons, switches); external pulse-per-second signal is also connected to this trigger input block
-trig_any: use a combination of the above (logical or, "any of")
-trig_all: require all trigger signals to be present (logical and, "all of")
-invert_trig_result v: uses v as the inversion pattern on the output of the combiner circuit
-invert_int v: uses v as the inversion pattern on the input INT
-invert_ext v: uses v as the inversion pattern on the input EXT
-invert_misc v: uses v as the inversion pattern on the input MISC
-mask_int m: uses m as the mask for input INT (only signals marked with 1 are passed through)
-mask_ext m: uses m as the mask for input EXT (only signals marked with 1 are passed through)
-mask_misc m: uses m as the mask for input MISC (only signals marked with 1 are passed through)

Diagnostic switches:

-pio v: write v to the internal trigger PIO before reading back trigger state; default is 0
-debug: continuously print streamer external-trigger input/control state for live debugging
