Hello all, I would like to set a timer to create a percent complete graph with the "QT GUI Level Gauge" block. I've created a flowgraph that does this and attached a screenshot and the flowgraph. My goal is to have this kind of "percent complete timer" to tell me when to move my antenna during a satellite pass. This means adding a piece of hardware and its connections to the attached flowgraph and I am worried about having two timers in the same flowgraph.
If I use this flowgraph and add hardware and use a head block with "samp_rate * duration" items it doesn't complete at the same time as the "percent complete timer". There are more items to complete for the hardware when the "percent complete timer" ends. I have tried to use the "Function Probe" block to probe the source of my hardware piece, but that doesn't work properly as the timing is off for both timers. Does anyone have a suggestion on how to calculate the percentage complete from the timer on the hardware piece instead of using a separate null sink as I have in the attached flowgraph? Thanks in advance, Chris
