| Abstract: | A real-time data acquisition system based on PCI Bus was introduced.The system was designed for single-ring absolute optical shaft encoder.In the system,PCI9052,which was developed by PLX corporation and compliant with PCI Specification 2.1,was designed as interface chip.Using powerful CPLD as logic control part,high-performance ADS803E produced by TI Company was adopted as core component for real-time data acquisition produced by linear CCD.It also described the details how to test the circuit board and how to program drivers with proper development tools.The result shows that the system satisfies data acquisition of single-ring absolute optical shaft encoder. |
