#include <LedEngine.h>
Inheritance diagram for LedEngine:
Provides a collection of special effects so that the code can be reused various places as feedback to to the user.
Cycling ("pulsing") and single-value setting are mutually exclusive - one will cut off the other
A flash will invert and override the current setting, so that it will "reset" after the flash. Flashes change mid-range values to extremes to make the flash visible (ie not just (1-current)) Normal invert will do simple inverses (just (1-current))
getSetting() returns value of last set(); getValue() returns what's actually being returned to Motion at the moment
There's some nice functions for using the LEDs to display numbers. This is handy for when you want to be free of the terminal.

The equation used is
The idea is that with a amplitude=1 and offset=0, it will start at 0, ramp up to 1, and then ramp down again. The arguments to this function will let you control all parameters of the cycle. You can get a blink-on/off instead of cycle on/off by using a very large amplitude. Definition at line 183 of file LedEngine.cc. Referenced by ccycle(), and EmergencyStopMC::EmergencyStopMC(). |

Allows convenient display of numerical information to the LEDs on the face. If overflow occurs, the face LEDs are set to flash on and off 3 every 333 milliseconds Definition at line 209 of file LedEngine.cc. |
|
Allows convenient display of percentage information to the LEDs on the face. Besides allowing a two-digit display, the 'edge' bar for each type is blinked to denote how full it is. So you can get up to a two-digit, base 5 display, with an extra digit of estimated value.
If overflow (>1) occurs, sets everything to .75. The left and right columns are combined with an OR operation. (they overlap on the top bar) Left and right designations are dog centric! Definition at line 269 of file LedEngine.cc. |
