perr1940 0:d38d627c922f 2 This is the main file for the "RyanEXO" control software.
perr1940 0:d38d627c922f 3 This sets up the main control loop that operates at a 1kHz frequency
perr1940 0:d38d627c922f 4 and controls the flow of the rest of the software
perr1940 0:d38d627c922f 5
perr1940 0:d38d627c922f 6 The configuration for the exo system that this software runs:
perr1940 0:d38d627c922f 7 amplifiers: 2 Copley Controls 10A digital amplifiers
perr1940 0:d38d627c922f 8 sensors: 2 Austria Microsystems 12 bit magnetic encoders, handled by encoders.h
perr1940 0:d38d627c922f 9 motors: 2 maxon EC90 DC brushless motors, handled by HipMotorControl.h (called in FSM.h)
perr1940 0:d38d627c922f 10 Knees: wrap spring clutch controlled by Firgelli PQ12P linear actuators, controlled in linearActuatorControl.h
