计时器检测要接计时器要用keil生成hex再用

《单片机应用系统设计与产品开发》配套源码-"SCM application system design and product development" complementary source

x5045相关程序，用keil c,其中附有两份很实用的资料-X5045-related procedures, using keil c, one with two very useful information

8051编译器 dos下 很小-8051 compiler under small dos

本代码是本人毕设所做的GPRS数传系统的软件部分，实现了PPP，UDP，IP协议的分层和打包，实现了嵌入式设计中的UDP/IP协议栈-the code is completed, I set up the GPRS data-transmission system software, to achieve the PPP, UDP, IP protocol layering and packaged to achieve the design of embedded UDP/IP protocol stack

该程序为基于51单片机的接口和片外应用的代码，在设计51单片机时可供参考，代码包括RS232通信、I2C、SPI、单总线、CAN总线、键盘、LED、LCD、AD/DA等应用。各工程在Keil调试通过，喜欢的朋友可供参考。-The program is based on the 51-chip microcontroller interface and application code, in the design of microcontroller 51 when the reference code, including RS232 communication, I2C, SPI, single-bus, CAN bus, keyboard, LED, LCD , AD/DA applications. Keil debugging the project passed, like a friend for reference.

这个是带了仿真功能的DS1302C程序,要搞DS1302可以参考一下的,仿真已通过-This is with a simulation function DS1302C procedures, wants to refer to the DS1302, simulation has passed
