Hallo everybody, I purchased a few rotary encoder and a bunch of 7segment displays to build a physical replacement of the Bendix KX165. I'm using Arduino which feeds data to FGFS on a serial connection. I'd like to update "instrumentation/comm[0]/frequencies/standby-mhz" property using the rotary encoder, I wonder what's the best strategy.
My current setup lets me read the rotary encoder rotation (it's a signed int value that measures it's direction and the amount of rotation; e.g. +3 equals three steps CW, -1 is 1 step CCW and 0 means it's not rotating) and send it to fgsf at 30Hz. This encoder is meant to be the KX165 physical equivalent of the frequency selector knob. I can send those values to FGFS but that's useless as it is now; I should make FGFS increment the "standby-mhz" property accordingly; problem is that using the generic protocol to feed those data I can't use the same approach as in kx165-1.xml where the "property-adjust" (with a proper <step> value) command has been used. I wonder how could I attack this part of the problem. Suggestions? My first thought was to feed the raw increment to fgfs, store it in a custom property and let fgfs run a nasal script to update standby-mhz accordingly in the background. I'm only guessing now, I don't even know if it's even possible. This scenario is of course of great interest to me since I'd like to use those rotary encoders for more stuff on FGFS. cheers, Roberto -- NEU: FreePhone - kostenlos mobil telefonieren und surfen!
