The Design and Implementation of Motion Control Card Based on DSP
A hardware implement scheme is proposed based on digital signal processor, and the complex programmable logic device and industry standard architecture bus is proposed. The dual-port random access memory communication circuit, I/O port address decoding circuit, two axis control output circuit and position detecting circuit are developed, the main program and interrupt-serving program of digital signal processor are designed by the idea of modularization. The static accuray of the motion control card is tested via special experimental device. The present analysis show that the designed circuit is effective and the static control precision of motion control card is satisfied.
