应用KEILC写的一个C52程序，单片机是用的STC的STC89C52主要写的是与EEPROM和DS1302及12232液晶的程序 -Application KEILC write a C52 program, the STC is a single-chip microcomputer of the main written STC89C52 with EEPROM and LCD DS1302 and 12,232 proced

STC89C52由于它本身自带有1K的EEPROM；支持掉电记忆，所以不用外接AT24C系列芯片；减少开发成本 -STC89C52 because it itself comes with 1K of EEPROM support power-down memory, so no external AT24C chips reduce development costs
