Description: This article was published in the third issue of single chip and embedded system application in 2005. I have contacted with Mr. Peng. He'll answer your questions
In early 2002, the author set out to write a working program of IC card prepaid meter, the meter using Philips company's eight 51 extension type single-chip microcomputer 87 lpc764 and requirement to realize many functions, including extinguish flashing, load calculation and control, indication and meters of various parameters in the query, etc., in short, to use the unit of time. The writer completed the program with ASM51 and completed the program with a little more than 2KB. Later, for a variety of reasons, the program was not really used, but only after some modifications were used to calculate the timing and load on an aging device. About a year later, I rewrote the code.
