| Abstract: | This paper introduces a data acquisition system in which the functions of 8-channel digital input, 8-channel digitaloutput and data acquisition for 8-channel analog signals have been realized by using the CP2102 of Silicon Co. as the USB interface and the high performance analog MCU ADuC845 as core of the system. The concept of software design is based on message mechanism and state machine mechanism. The system is of simplicity in design, smaller volume, low cost and wider prospect of application. |
