不同于一般形式的软件编程，嵌入式系统编程建立在特定的硬件平台上，势必要求其编程语言具备较强的硬件直接操作能力。无疑，汇编语言具备这样的特质。但是，由于汇编语言开发的复杂性，它并不是嵌入式系统开发的一般选择。而与之相比，C语言--一种"高级的低级"语言，则成为嵌入式系统开发的最佳选择。-Unlike most forms of software programming, embedded systems programming based on the specific hardware platform, is bound to require its programming language with a strong ability to direct hardware. Undoubtedly, the compilation of language with such qualities. However, the assembly language development complexity, it is not embedded systems development in general choice. But compared with C language-- a "senior vulgar" language, embedded systems development as the best option.
