头文件stc单片机具有在应用编程，调试起来比较方便；带有10位AD；内部eeprom；可在1T/机器周期下工作，速度是传统51单片机的12倍；下面是我写的AD和EEPROM的驱动C代码-STC12C2052AD.H Header file for 8xC31/51, 80C51Fx, 80C51Rx+ Copyright (c) 1988-1999 Keil Elektronik GmbH and Keil Software, Inc. All rights reserved.

是STC主芯片驱动，用C语言编程，完全可移植到其他51内核单片机主芯片上，将IO口修改即可，使用的编程软件为KEIL-Is the STC the main chip drive, using the C programming language, fully portable to the other 51 core microcontroller main chip IO port modifications, using the programming software for KEIL

用STC最小系统的实时时钟设计实现数字钟。 可以切换年月日时分秒显示，支持时钟设计功能 用Keil C51编程实现上述功能 用Keil与Proteus联调. -With minimum on STC system real time clock design for digital clock. Can switch when (date) (month) (year), according to minutes support clock design functions Use
