3.1.4 Interpolation commands

(21)i8091_INTP_PULSE(unsigned char cardNo, int Xpulse, int Ypulse) This command will move a short distance (interpolation short line) in X-Y plane. This command provided a method for user to generate an arbitrary curve in X-Y plane.

cardNo : board number 0~19. Restriction:

− 2047≤ # Xpulse≤ 2047

−2047≤ #Ypulse≤ 2047

Example: i8091_INTP_PULSE(1,20,20); i8091_INTP_PULSE(1,20,13); i8091_INTP_PULSE(1,20,7); i8091_INTP_PULSE(1,20,0); i8091_INTP_PULSE(1,15,-5);

(22)i8091_INTP_LINE(unsigned char cardNo, long Xpulse, long Ypulse) This command will move a long distance (interpolation line) in X-Y plane. The CPU on I-8091 card will generate a trapezoidal speed profile of X-axis and Y-axis, and execute interpolation by way of DDA chip.
