/*
|
||||||
|
|
||||||
|
A servo is activated by creating an instance of the Servo class passing the desired pin to the attach() method.
|
||||||
|
The servos are pulsed in the background using the value most recently written using the write() method
|
||||||
|
|
||||||
|
Note that analogWrite of PWM on pins associated with the timer are disabled when the first servo is attached.
|
||||||
|
Timers are seized as needed in groups of 12 servos - 24 servos use two timers, 48 servos will use four.
|
||||||
|
|
||||||
|
The methods are:
|
||||||
|
|
||||||
|
Servo - Class for manipulating servo motors connected to Arduino pins.
|
||||||
|
|
||||||
|
attach(pin ) - Attaches a servo motor to an i/o pin.
|
||||||
|
attach(pin, min, max ) - Attaches to a pin setting min and max values in microseconds
|
||||||
|
default min is 544, max is 2400
|
||||||
|
|
||||||
|
write() - Sets the servo angle in degrees. (invalid angle that is valid as pulse in microseconds is treated as microseconds)
|
||||||
|
writeMicroseconds() - Sets the servo pulse width in microseconds
|
||||||
|
read() - Gets the last written servo pulse width as an angle between 0 and 180.
|
||||||
|
readMicroseconds() - Gets the last written servo pulse width in microseconds. (was read_us() in first release)
|
||||||
|
attached() - Returns true if there is a servo attached.
|
||||||
|
detach() - Stops an attached servos from pulsing its i/o pin.

/*
|
||||||
|
|
||||||
|
A servo is activated by creating an instance of the Servo class passing the desired pin to the attach() method.
|
||||||
|
The servos are pulsed in the background using the value most recently written using the write() method
|
||||||
|
|
||||||
|
Note that analogWrite of PWM on pins associated with the timer are disabled when the first servo is attached.
|
||||||
|
Timers are seized as needed in groups of 12 servos - 24 servos use two timers, 48 servos will use four.
|
||||||
|
The sequence used to sieze timers is defined in timers.h
|
||||||
|
|
||||||
|
The methods are:
|
||||||
|
|
||||||
|
Servo - Class for manipulating servo motors connected to Arduino pins.
|
||||||
|
|
||||||
|
attach(pin ) - Attaches a servo motor to an i/o pin.
|
||||||
|
attach(pin, min, max ) - Attaches to a pin setting min and max values in microseconds
|
||||||
|
default min is 544, max is 2400
|
||||||
|
|
||||||
|
write() - Sets the servo angle in degrees. (invalid angle that is valid as pulse in microseconds is treated as microseconds)
|
||||||
|
writeMicroseconds() - Sets the servo pulse width in microseconds
|
||||||
|
read() - Gets the last written servo pulse width as an angle between 0 and 180.
|
||||||
|
readMicroseconds() - Gets the last written servo pulse width in microseconds. (was read_us() in first release)
|
||||||
|
attached() - Returns true if there is a servo attached.
|
||||||
|
detach() - Stops an attached servos from pulsing its i/o pin.
