This program implements a PIC-Based fuzzy inference engine for the Fudge fuzzy development system from Motorola.
It works by taking the output from Fudge for the 68HC11 processor, and converting it to a MPASM compatible assembler file using the convert
batch file.
This file can then be incorporated with fuzzy.asm to create a fuzzy inference engine.

基于PIC單片機(jī)的低功耗讀卡器硬件設(shè)計(jì):本文提出了一個(gè)完整的基于串口的智能讀卡器子系統(tǒng)設(shè)計(jì)方案并將其實(shí)現(xiàn)。讀卡器的設(shè)計(jì)突出了小型化的要求，全部器件使用貼片封裝。為了減小讀卡器的體積，設(shè)計(jì)中還使用了串口竊電的技術(shù)，使用串口信號(hào)線直接給讀卡器供電。為此，讀卡器使用了省電的設(shè)計(jì)，采用了省電的集成電路，并大膽簡(jiǎn)化了許多傳統(tǒng)的設(shè)計(jì)電路。關(guān)鍵字： 讀卡器， 單片機(jī)， 串口竊電
Abstract： This paper aims to put forward a complete design of Smart IC card reader based onSerial Port and propose the way of realizing it for the purpose of Network Security. SMD isadopted to make Smart IC reader smaller in this design. To reduce the volume of Smart ICreader， Serial Port powered technology is employed to get power from the signal line of Serial Port. For this reason， low-power consumption components are adopted in the design and some traditional designs are simplified to reduce the power consumption.Keywords： Card Reader； Single-chip Computer； Serial Port Powered
