实现STM32的bootloader设计，参考代码，可以实现stm32串口bootloader(The bootloader achieve STM32 design, reference code, can achieve stm32 serial bootloader)

json编解码,json源文件，交叉变异后，或者直接编译后，用于jons解析和生成json格式数据。(json-c:Json codec,json source file, cross mutation, or directly compiled, jons for parsing and generating json format data.)

主要实现了STM32F10X的串口dma，实现了flash操作；并且 直接可以编译运行;(It mainly implements the serial port DMA of STM32F10X, realizes flash operation, and compiles and runs directly.)

实现数码管，矩阵键盘结合的计算器功能，基于51单片机的代码适合初学者参考(Realize the calculator function of the combination of digital tube and matrix keyboard)

Arduino LCD library

Xilinx虚拟连接，这是一种基于TCP/IP协议的通信技术，以实现JTAG功能，通过这样的连接，可以访问开发的FPGA或者SOC，而不需要通过传统的JTAG电缆。(Xilinx Virtual Cable (XVC) is a TCP/IP-based communication protocol that acts like a JTAG cable and provides a means to access and debug your FPGA or SoC design without using a physical cable. In this document are the general details of this XVC 1.0 protocol.)

rs232实验 可以看看是综合实验 需要的人 是51的板子 用keil编译(the rs232 experiment to see people in need of comprehensive experimental 51 board keil compiler)

某地220kv母线负荷数据，对电力研究很有用(A 220kV bus load data, very useful for electric power research)

飞思卡尔智能车电磁组源代码，包括ad采样，pid控制，速度控制，方向控制(freescale smart car code)

能够实现通过红外遥控器控制电机的正反，停止转动。(Can be achieved through an infrared remote control motor forward and reverse, stop turning.)
