|+# readme.mb : Readme file for chipKIT/MPIDE Servo library|
|+The Servo library allows a sketch to output RC servo pulses on up to 24 of the I/O pins|
|+at a time. These servo pulses are all controlled by hardware timers and interrupts, so that|
|+once they are started, they continue to output pulses with no sketch code interaction.|
|+Use this library to control up to 24 RC servos at a time, using either degree (0 to 179)|
|+parameter or microsecond pulse durations (from 544us to 2400us).|
|+See the Servo.cpp and Servo.h files for detailed usage information.|
|+The way the library works is to keep a list of all possible servos. Each time you create|
|+a new Servo object and attach it to a pin, the next servo in the list is populated with|
|+the pin number, the duration (in uS) and which of three timers will control that servo.|
|+The three timers are dynamically turned on/off as needed to support the number of servos|
|+used, with up to 8 servos on each of the three timers. Each time the timer fires, it|
|+clears the current servo pin and set the next one in the list, then sets itself to fire|
|+again in the future the duration of the new servo high period. After all servos have fired,|
|+the timer then sets itself to fire such that the entire process repeats every 20ms or so.|
|+Even though timers are used, the actual pin setting and clearing is done in software in|
|+the timer's ISR. Thus these servos will have jitter based upon what other interrupts|
|+are enabled and running on the system at the time.|
|+See Servo.cpp and Servo.h for more information on special precautions when using the|
|+This library was adatped for the PIC32 architecture from the Arduino Servo library. See|
|+Servo.cpp for more history information|
