| Summary: | 碩士 === 樹德科技大學 === 電腦與通訊研究所 === 92 === With the rapid development of information technology, especially the omnipresence of internet and the fast unification of 3C(computer, communication, and consumer electronics), the application of embedded systems is becoming more and more popular. The embedded system has several advantages, such as small core, specialization, concise system, and highly practical operating system software. This thesis studies the Z8 Encore! Series of 8-bit Micro Controller Chips(MCU) made by Zilog company, which is rarely used in the current market. Those MCUs integrate 64KB flash memory, 10-bit analog/digital converter, system chip debugger, 24 vector interrupter, and 60-pin common I/O connector. This thesis utilizes the 16 sets of digital input isolation point system designed into the Z8 Encore! Series of 8-bit Micro Controller Chips(MCU) made by Zilog company, which adopted the industrial standard, Modbus RTU protocol. Through this protocol, controllers can communicate with each other as well as acquire data through OPC Server. They support standard 2-wire RS-485 serial equipment to monitor and acquire data. Besides, this thesis studies and designs data acquisition system in current semiconductor packaging and testing factories, which utilize GPIB interface to monitor data flow between the handler, Epsome NS-6040 chip testing platform and tester, Agilent 93000C single-chip tester. As a result, we are able to analyze the communication data collected through the data acquirer. The method used in this thesis is to replace the NS-6040 chip testing platform with a personal computer and 93000C single-chip tester with a oscilloscope while using GPIB interface for communicating messages and controlling. After testing, the data acquirer is able to effectively monitor all messages through GPIB interface.
