1. How would I compute for the pulse width that I should give my servo. example I want my servo to be in 65 degrees position. How will I compute for that. My servo is HS-755HB (hitec). Its specs are here:
Control System: +Pulse Width Control 1500usec Neutral
Required Pulse: 3-5 Volt Peak to Peak Square Wave
Operating Voltage: 4.8-6.0 Volts
Operating Temperature Range: -20 to +60 Degree C
Operating Speed (4.8V): 0.28sec/60 degrees at no load
Operating Speed (6.0V): 0.23sec/60 degrees at no load
Stall Torque (4.8V): 153 oz/in. (11kg.cm)
Stall Torque (6.0V): 183 oz/in. (13.2kg.cm)
Operating Angle: 45 Deg. one side pulse traveling 400usec
360 Modifiable: Yes
Direction: Clockwise/Pulse Traveling 1500 to 1900usec
Current Drain (4.8V): 8mA/idle and 230mA no load operating
Current Drain (6.0V): 8.7mA/idle and 285mA no load operating
Dead Band Width: 8usec
Motor Type: 3 Pole Ferrite
Potentiometer Drive: Indirect Drive
Bearing Type: 1 Bearing and 1 Oilite Bushing
Gear Type: Karbonite Gears
Connector Wire Length: 11.81" (300mm)
Dimensions: 2.3" x 1.1"x 2.0" (59 x 29 x 50mm)
Weight: 3.88 oz.. (110g)
2. The datasheet states that the minimum pulse I can give the servo must be 900microseconds. I tried giving it 600 microseconds and I can get a bigger angle change and I need that much angle, can I use 600 microseconds even if the datasheet says that the minimum is 900 micro?
