Storing history of analog values

merriweather.randolph All Messages By This Member #133012 I want to keep a history of 5 to 10 changes to a single analog value. Does anyone have a suggestion of how I might accomplish this? mer
Jeremy Weatherford #133014 Quick and dirty SIMPL solution is to use an ABUF to make a sort of delay line, and send a WPULSE (single logic wave pulse) to the enable to shift everything by one: Value -> Value1 Value1 -> Value2 Value2 -> Value3 Value3 -> Value4 etc. Value1 will be the most recent saved, Value4 will be the oldest. Use an ARAM if it needs to survive program reboots.

mjrtoo2000 #133024 I might use a ring buffer, and an ABUF with multiple selects defined driven by the ring buffer. Setup the ring buffer clock and Store/Recall on the ABUF as you see fit. toggle quoted message Show quoted text --- In Crestron@..., "merriweather.randolph" <merriweather.randolph@...> wrote: I want to keep a history of 5 to 10 changes to a single analog value.

merriweather.randolph All Messages By This Member #133807 Thanks, Jeremy. I thought I had it figured out, but I'm getting an odd behavior that I don't understand. I setup the abuf as you suggested enabled by the wpulse and I have the output of the abuf feeding an aram (ones on store, recall and select1) whose output feeds the output side of the argument definition. Watching the signals in debugger the output of the buffer is correct, but I don't get an output from the aram until the program is reset. toggle quoted message Show quoted text --- In Crestron@..., Jeremy Weatherford <xidus.net@...> wrote: Quick and dirty SIMPL solution is to use an ABUF to make a sort of delay line, and send a WPULSE (single logic wave pulse) to the enable to shift everything by one: Value -> Value1 Value1 -> Value2 Value2 -> Value3 Value3 -> Value4 etc. Value1 will be the most recent saved, Value4 will be the oldest.

Jeremy Weatherford #133812 To use an ARAM this way (with 1s on store, recall, and select1), the input signal names need to be the same as the output signal names. While the program runs, it's just storing data to NVRAM. When the program starts up, it sees the 1 on recall and sends the stored values to the outputs. It doesn't output anything else until the program restarts. On Mon, Mar 7, 2011 at 12:43 PM, merriweather.randolph <merriweather.randolph@...> wrote: Thanks, Jeremy.
