Analog Inputs
General Usage
Analog inputs can be used eg. for:
- yoke / aileron
- control column / elevator
- rudder pedals
- toe brakes
- multi-engine throttle levers
- reverser levers
- nose gear steering tiller
- panel brightness control
- instrument brightness control
- ...
PHCC Analog Input Channels
Features
- integrated on the PHCC motherboard
- 35 analog-in channels
- 3 of them priority (scanned 15 times more often than the other 32)
- well suited for aileron, elevator, and rudder control
- 3 of them priority (scanned 15 times more often than the other 32)
- measures voltage, not current (like gameports)
- jitter reduction algorithm smoothes out spikes in input
- scan rate: TBD.
- PHCC host control program can configure each channel individually:
- to relay it to a kernel joystick driver
- this allows all applications to use PHCC inputs as joystick axes
- to use it internally, eg.
- to control brightness of your backlighting
- to map to some floating point number within flightgear, eg. spoilers
- to relay it to a kernel joystick driver
- mechanical connection: pinheader with 3 pins.
- compatible with potentiomenters from < 1kOhm to 100kOhm
- can be used with LVDTs (LVDT signal conditioning circuit necessary)
- several other sensor types work as well
