用C语言模拟I2C时序功能，已经调试通过，可以直接使用

主要实现FPGA和总线模式下的通信可以实现8051对FPGA的读写操作-The main FPGA and bus modes of communication can be achieved under the 8051 pairs of the FPGA to read and write operation

4位可逆计数器：将50MHz的时钟进行 分频后的结果作为时钟控制，根据输入进行条件判断，再通过设置一个四位的向量将结果输出，利用数码管显示在实验板上-CNTR 4: will be conducted at 50MHz clock frequency as the clock after the control conditions to determine the basis of inputs, and then set up a four through the results of the vector output, digital display board in the experiment

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.

这是一个ntripclient的源码，主要是设置各种参数从ntripcaster上获取GNSS数据，然后将数据通过串口输出或写在文件里，源码比较实用，适合在linux操作系统下开发
