EXTERNAL DEVICE CONTROL USING IBM PC’s CENTRONICS PRINTER PORT
نویسنده
چکیده
IBM PCs with parallel printer ports are widely available in teaching and research laboratories. This paper describes a novel system for controlling any equipment in general, positioning with stepping motors in particular via the parallel Centronics printer port of an IBM PC or compatible. Techniques are presented for exploring the unused parallel port or exploiting the Centronics printer port for control. Programs are developed for position control of stepper motor using Macro Assembler MASM 86.
