u8 axis;// Axis number
u16 csr = 0;// Communication status register
i32 bufferSize = 100;// The size of the buffer to
allocate on the //motion controller
u32 totalPoints = 100;// The number of high speed
capture to //acquire
i32 capturedPositions[100];// Array to store the
captured //positions
f64 actualInterval;// The interval at which the
motion controller can //really contour
