PySSC32

This is simple interface to control RC servos with an SSC32 board.

Features:

  • Direct and grouped queries (#<N>P<US> and <SERVO_POS>...T<MS>)
  • Angle (degrees or radians) to microsecond position calculation
  • Simple configuration file that help to map board output pin to servo name and provide limits.
  • Sequences scripts (in YAML format)

Example

>>> import ssc32
>>> import math
>>> ssc = ssc32.SSC32('/dev/ttyUSB0', 115200, count=32)
>>> ssc[2].position = 2000
>>> ssc[3].name = 'pan'
>>> ssc[4].name = 'tilt'
>>> pan_servo = ssc['pan']
>>> tilt_servo = ssc['tilt']
>>> pan_servo.degrees = 0
>>> tilt_servo.radians = math.pi/4
>>> ssc.commit(time=1000)
>>> ssc.is_done()
False
>>> ssc.is_done()
True
>>> ssc.description = 'My camera's pan/tilt'
>>> ssc.save_config('my_pantilt.cfg')
