kaselite Posted November 20, 2021 Report Posted November 20, 2021 Hello Goran, i have a hardware-based autopilot interface. On the device each key is using 1 dataref. It works.... but not as smoothly as the virtual buttons. I ran a dataref monitoring tool, to see what datarefs used when each virtual key is pressed. I was surprised as i found that of then there is more than one for many of the buttons. I have a few questions: 1. When there are multiple datarefs, are these being issues by each key or is it a chain reaction from 1 initial dataref? 2. When there are multiple datarefs, are they required to make each function work correctly? 3. If #2 is true, are they issued all at once, or in a sequence? Im planning to run tests tomorrow, i am wondering if anyone has figured something out here. The commands from my monitoring tests: FLC sim/GPS/g1000n1_flc SPD sim/autopilot/knots_mach_toggle tbm900/actuators/ap/spd VS UP/DN tbm900/actuators/ap/nose_up tbm900/actuators/ap/nose_down VS sim/autopilot/vertical_speed sim/GPS/g1000n1_vs tbm900/actuators/ap/vs VNY sim/autopilot/vnav sim/GPS/g1000n1_vnv tbm900/actuators/ap/vnv ALT sim/autopilot/altitude_hold sim/GPS/g1000n1_alt tbm900/actuators/ap/alt YD sim/systems/yaw_damper_toggle tbm900/actuators/ap/yd AP sim/autopilot/autothrottle_off sim/autopilot/fdir_servos_toggle sim/autopilot/fdir_toggle sim/autopilot/servos_toggle sim/GPS/g1000n1_ap sim/GPS/g1000n1_fd tbm900/actuators/ap/ap BANK tbm900/actuators/ap/bank FD sim/autopilot/fdir_toggle sim/GPS/g1000n1_fd tbm900/actuators/ap/fd NAV tbm900/actuators/ap/nav APR sim/autopilot/glide_slope tbm900/actuators/ap/apr HDG sim/autopilot/heading sim/GPS/g1000n1_hdg tbm900/actuators/ap/hdg Quote
Goran_M Posted November 22, 2021 Report Posted November 22, 2021 (edited) Datarefs fall into different categories Indicators - (A heading indicator that displays the aircrafts current heading) actuators - (The knob on an autopilot heading dial that changes the heading bug and commands the aircraft to follow a specific heading) (Also some are writeable and some are not. Some are ratios...0 to 1... and some are booleans...negative numbers, 0, positive numbers) And then they can fall into the different types of systems air driven gyro electric AHARS Whenever you see a "TBM" dataref, it's a custom dataref that is code driven. a "sim" dataref is a default dataref that comes with X-Plane. In some cases, the TBM uses default datarefs, because many of those work very well. To answer your questions, 1. a dataref that is an actuator can absolutely trigger a sequence of events that trigger and activate indicators, and if there is code attached, they can also trigger other actuator datarefs. 2. actuators and indicators, yes. In most cases. 3. 1 triggers the next, and then the next, and so on. (I hope this answers your question). Edited November 22, 2021 by Goran_M Quote
