c++实现编译原理词法分析

说明：  This is the basic algorithm.

这是Windows程序设计（第五版）第11章-第15章的源代码！(This is a Windows program design (fifth edition) Chapter 11- Chapter 15 of the source code!)

可以实现大地坐标系与三维空间直角坐标系之间的转换。高斯正反算等(The transformation between geodetic coordinate system and three-dimensional space rectangular coordinate system can be realized. Gauss forward and backward calculation, etc.)

包括多种开发板的白皮书，基础学习单片机知识(Intelligent tracking car)

MS5基于STM32F103设计开发，可以在Keil下软件仿真调试，不需要实物硬件板子，UART1作为人机窗口。硬件测试是基于正点原子的miniSTM32F103RBT6板子测试，资料是开源的。MS5主要基于MS4（基于NXP Cortex M3）升级而来，因为在2011年基于MS4做了6KW高频焊接机，增加了界面部分，采用函数指针加消息机制，感觉比较简单而有效，性能比较不错，尤其是针对工业产品，系统节拍分时设计有进一步的体会，把这两点融入到MS5中，同时修改了串口UART发送系统等待问题，先把串口数据放到一个buff中，系统节拍去检测buff，当有数据时，每个节拍发送一个，这样就避免了以前发送的时候，需要很长的等待问题。(MS5 based on the design and development of STM32F103 in Keil software simulation debugging, does not require physical hardware board UART1 as a man-machine window. The hardware test is based the the punctuality atoms miniSTM32F103RBT6 board test, and the information is open source. MS4 MS5 mainly based on (upgrades from NXP Cortex M3), because in 2011 based on the MS4 6KW high-frequency welding machine, increase the interface part of the function pointer plus message mechanism, feeling relatively simple and effective, and the performance is quite good, beats especially for industrial products, systems, time-sharing design further experience, these two points into the MS5 while waiting for problems to modify the serial UART transmit the first serial data into a buff system beats to detect buff, data, send each beat, thus avoiding the previously sent, the long wait.)

实现象ToolTips那样的上下文帮助(The Example of implementing the help of tooltip style)

说明：  华大MCU双电阻采样无感FOC方案，适用于对成本敏感场合的应用(Huada MCU double resistance sampling non inductive FOC scheme)

  autoquad项目esc32部分的源代码，基于STM32F103C8T6,使用C语言kei环境下编译的。
