总的来说，在uClinux上的开发和标准Linux还是很类似的。通常可以按照下面的步骤去设计和调试： 建立基于以太网的开发环境； 如果所设计的程序和硬件的关联不大，那么一定要在标准Linux上先编译和调试通过。灵活地使用gcc和gdb将大大节省时间； 将x86上的GCC编译好的应用程序用交叉编译工具来编译；如果编译时发现错误，那么很可能存在以下问题： 交叉编译器或库文件的路径不正确；最彻底的解决办法是重新装一次编译器； 遇到库不支持的函数；此时需要自己把函数的实现做成另外一个库供应用程序使用。如果是uClinux本身不支持的调用，那么就需要改写代码了。-Overall, the uClinux on the development and standard Linux is still very similar. Usually can use the following steps to design and debug : Ethernet-based development environment; If the design of the procedure and not linked to the hardware, then it must be the first standard Linux compiler and debugging through. Flexibility in the use of gdb and gcc will greatly save time; X86 will be on the GCC-compiled application with cross-compiler tool to compile; If you compile time error is found, it was very likely that the following issues : cross-compilers or libraries are not the correct path; The most radical solution is a re-installed time compiler; encountered does not support functions; At this time the need to

SPI主机驱动，利用74HC595驱动7段数码管进行数字显示。

24CXX全系列EEPROM底层读写函数，自己写的，IIC接口函数自己根据具体方法可以模拟或硬件实现-qi bottom of the whole series EEPROM read and write functions, wrote, IIC interface function in accordance with their own specific methods can be simulated or hardware

应用背景TM1628控制10位7段数码管，小数点请另外方式控制，STM32F030用keil5.10可以直接编译通过关键技术TM1628是很好用的专门控制数码管的IC，成本低，通讯方式简单驱动电流每段可以最大50ma，对于IO紧张的单片机做显示是一个不错的选择，控制共阴数码管跟共阳数码管写入数据方式不一样，共阳较麻烦，这里这份代码可以给共阳方式接法的提供参考，已经成功经过硬件调试。
