martinsimpson 1:3ca91ad8e927 2 Simple Routine for Nucleo Board for ROCO104 Buggy Motor Control and Microswitches
martinsimpson 1:3ca91ad8e927 3 Heavy edit from previous ROCO103PP code
martinsimpson 1:3ca91ad8e927 4 Motor Class can now be instansiated with all four pins needed to control the H Bridge
martinsimpson 1:3ca91ad8e927 5 with a member functions as follows
martinsimpson 1:3ca91ad8e927 6
martinsimpson 1:3ca91ad8e927 7 Motor::Speed(float A, Float B) range -0.1 to +1.0 to give full reverse to full forward for A/B motors
martinsimpson 1:3ca91ad8e927 8 Motor::Stop() STOP
martinsimpson 1:3ca91ad8e927 9 Motor::Fwd(float) Forward but floating point number (range 0.0 to 1.0)
martinsimpson 1:3ca91ad8e927 10 Motor::Rev(float) Reverse but floating point number (range 0.0 to 1.0)
