Button is rotate counterclockwise.I.e. when encoder port B is low level, the port level state variable is equal to the change clockwise
0X03 is measured, confirms encoder knob to turn clockwise.When encoder port C is low level, the port level state becomes
Amount is equal to the variable 0X05 counterclockwise, and confirmation encoder knob is rotate counterclockwise.
S400：The first Interruption and the second Interruption are closed, external interrupt is opened, port level state variable is clear
0.After once rotation detection is completed, each port level state variable clear 0, variable left four restarts to revolve next time
Turn detection,
If at least two port level is low or does not collect second in setting duty cycle in step S300
Interruption condition, then close the first Interruption and the second Interruption, external interrupt is opened, by port level state variable
Clear 0.In a duty cycle, if the second Interruption is not triggered all the time, will close the first Interruption is the second timing
Interrupt, open external interrupt, restart rotation detection.In the duty cycle, if there is two or more port electricity simultaneously
Put down to be low, then port level state variable clear 0, close the first Interruption and the second Interruption, open external interrupt.Institute
Stating duty cycle can be set according to demand, such as be set to 10 milliseconds, 50 milliseconds or 80 milliseconds time cycles, in task week
Turn off the first Interruption, the second Interruption by force if rotation detection is not completed in phase, open external interrupt.
