(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.  - */ - -#ifndef Servo_h -#define Servo_h - -#include <inttypes.h> - -/*  - * Defines for 16 bit timers used with  Servo library  - * - * If _useTimerX is defined then TimerX is a 16 bit timer on the curent board - * timer16_Sequence_t enumerates the sequence that the timers should be allocated - * _Nbr_16timers indicates how many 16 bit timers are available. - * - */ - -// Say which 16 bit timers can be used and in what order -#if defined(__AVR_ATmega1280__) || defined(__AVR_ATmega2560__) -#define _useTimer5 -#define _useTimer1  -#define _useTimer3 -#define _useTimer4  -typedef enum { _timer5, _timer1, _timer3, _timer4, _Nbr_16timers } timer16_Sequence_t ; - -#elif defined(__AVR_ATmega32U4__)   -#define _useTimer1  -typedef enum { _timer1, _Nbr_16timers } timer16_Sequence_t ; - -#elif defined(__AVR_AT90USB646__) || defined(__AVR_AT90USB1286__) -#define _useTimer3 -#define _useTimer1 -typedef enum { _timer3, _timer1, _Nbr_16timers } timer16_Sequence_t ; - -#elif defined(__AVR_ATmega128__) ||defined(__AVR_ATmega1281__)||defined(__AVR_ATmega2561__) -#define _useTimer3 -#define _useTimer1 -typedef enum { _timer3, _timer1, _Nbr_16timers } timer16_Sequence_t ; - -#else  // everything else -#define _useTimer1 -typedef enum { _timer1, _Nbr_16timers } timer16_Sequence_t ;                   -#endif - -#define Servo_VERSION           2      // software version of this library - -#define MIN_PULSE_WIDTH       544     // the shortest pulse sent to a servo   -#define MAX_PULSE_WIDTH      2400     // the longest pulse sent to a servo  -#define DEFAULT_PULSE_WIDTH  1500     // default pulse width when servo is attached -#define REFRESH_INTERVAL    20000     // minumim time to refresh servos in microseconds  - -#define SERVOS_PER_TIMER       12     // the maximum number of servos controlled by one timer  -#define MAX_SERVOS   (_Nbr_16timers  * SERVOS_PER_TIMER) - -#define INVALID_SERVO         255     // flag indicating an invalid servo index - -typedef struct  { -  uint8_t nbr        :6 ;             // a pin number from 0 to 63 -  uint8_t isActive   :1 ;             // true if this channel is enabled, pin not pulsed if false  -} ServoPin_t   ;   - -typedef struct { -  ServoPin_t Pin; -  unsigned int ticks; -} servo_t; - -class Servo -{ -public: -  Servo(); -  uint8_t attach(int pin);           // attach the given pin to the next free channel, sets pinMode, returns channel number or 0 if failure -  uint8_t attach(int pin, int min, int max); // as above but also sets min and max values for writes.  -  void detach(); -  void write(int value);             // if value is < 200 its treated as an angle, otherwise as pulse width in microseconds  -  void writeMicroseconds(int value); // Write pulse width in microseconds  -  int read();                        // returns current pulse width as an angle between 0 and 180 degrees -  int readMicroseconds();            // returns current pulse width in microseconds for this servo (was read_us() in first release) -  bool attached();                   // return true if this servo is attached, otherwise false  -private: -   uint8_t servoIndex;               // index into the channel data for this servo -   int8_t min;                       // minimum is this value times 4 added to MIN_PULSE_WIDTH     -   int8_t max;                       // maximum is this value times 4 added to MAX_PULSE_WIDTH    -}; - -#endif  |
