FlexAPI Object Properties

Mark Erbaugh

There must be something I don't understand about the properties of some FlexAPI C# objects. 

In response to a PanadapterAdded message, my program creates a display form. It sets panadapter.CenterFreq and waterfall.CenterFreq to 3.919 (hard-coded for now). In my waterfall.OnDataReady event, I query the panadapter.CenterFreq and waterfall.CenterFreq properties and they are changed.  They are 14.1. Also, the Waterfall tile.FrameLowFreq shows around 13. 


Interestingly, when I plot the panadapter, it seems to be at 3.919.

I'm jealous! I had a hard time getting any of it to be even close to the correct signal. The spectrum display ( panadapter) was a piece of cake compared to the waterfall. Another issue I have, in my code I use Color.From.ARGB to get the correct color and intensity of the signal. That turns out to be processor intensive and can bog down the CPU. Eric told me they use a lookup table for the waterfall colors in SSDR. That seems to be a better solution. But, I never got around to trying to build one. From all your posts it appears you're making great progress. Makes me want to get back at it. James WD5GWY

It's pretty likely that the slowdown is elsewhere in my code. You're really doing good.
When can we expect the Erbaugh app to show up? :-)
