Re: [AVR-Chat] Re: futaba S3003 servo

2004-06-20 by jay marante

ok... assuming phil's data, this is what i sofar understand:
 
i should send a signal to the servo with 2ms (5V) to rotate it at maximum position and 1ms (5V) for minimum position. 
 
should i send this signal once (just sigle pulse) for the servo to rotate, say for maximum position? or should i send a continuous signal of 2ms length of 5V? and if that should be the case, what should be the length of the 0V in between the 5V signals? thanks...

;For Futaba Servos
..equ    Futaba_Min      = 1000  ;Microseconds for minimum position
..equ    Futaba_Max      = 2000  ;Microseconds for maximum position
..equ    Futaba_Range    = (Futaba_Max - Futaba_Min)

;For Cirrus Servos
..equ    Cirrus_Min      = 400   ;Microseconds for minimum position
..equ    Cirrus_Max      = 2000  ;Microseconds for maximum position
..equ    Cirrus_Range    = (Cirrus_Max - Cirrus_Min)

;For JR Servos
..equ    JR_Min          = 1000  ;Microseconds for minimum position
..equ    JR_Max          = 2000  ;Microseconds for maximum position
..equ    JR_Range        = (JR_Max - JR_Min)

Pulled from my GSV5 code that does eight mix-and-match servos with 8 bit control
