51单片机C语言的编程技巧 在进行单片机应用系统设计时．汇编语言是一种常用的软件工具。它能直接操作硬件．指令的执行速度快。但其指令繁育统的固有格式受硬件结构的限制很大．且难于编写与调试．同时其可移植性也较差。随着单片机硬件性能的提高．其工作速度越来越快．因此在编写单片机应用系统程序时．更着重于程序本身的编写效率。本文介招的C51交叉编译器就是解决连一问题的利器-51 microcontroller C programming language skills during SCM application system design. Assembly Language is a common software tools. It can directly operate the hardware. Order Execution speed. But their breeding EC Directive format by the inherent structural limitations of hardware great. It is not easy to prepare and debugging. While its portability also poor. With SCM performance of hardware. Their work ever faster. Therefore, in preparing microcontroller applications procedures. More focused on the preparation process itself efficiency. This paper introduces the C51 cross compiler is not even solve the problem of a sharp object
