针对LPC2100系列芯片的Keil开发工程模板，代码清晰，已编译通过！

用KEIL 5进行嵌入式开发时，用盗版JLINK经常在调试前弹窗出来warning the connected J-link is defective. Proper operation cannot be guaranteed Jlink information Firmware J-link ARM V8 这个问题经常导致调试过程中频繁退出，或无法停止，无法reset，单步调试异常等现象 把压缩包中的文件替换到在Keil的安装文件夹中，Keil/ARM/Segger/下 再次重启Keil，就可以正常调试了

keil中所有库函数的帮助文件。 The C51 run-time library provides you with more than 100 predefined functions and macros to use in your 8051 C programs. This library makes embedded software development easier by providing you with routines that perform common programming tasks such as string and buffer manipulation, data conversion, and floating-point math operations. Typically, the routines in this library conform to the ANSI C Standard. However, some functions differ slightly in order to take advantage of the features found in the 8051 architecture. For example, the function isdigit returns a bit value as opposed to an int. Where possible, function return types and argument types are adjusted to use the smallest possible data type. In addition, unsigned data types are favored over signed types. These alterations to the standard library provide a maximum of performance while also reducing program size. All routines in this library are implemented to be independent of and to function using any register bank.
