　　网页flash抓取器 7.0(信捷PLC编程软件XDPProgcc详述详述的数据结构和算法

)

　　新捷PLC编程软件XDPPro收录arm-none-eabi的gcc程序。测试中使用的模型的SOC是ST的Cortex-M7。C语言编程的自由度非常高，如果你有能力接管编译过程，各种高级数据结构就是锦上添花。

　　初步测试了GCC的调用过程。从捕获的信息来看，用户手册中没有详细说明的魔术操作在源代码中一目了然。

　　如果用C语言来开发实用的数据结构和算法，这个小PLC的应用场景还是很多的。毕竟有1MB的程序空间，要填满也不是一件容易的事。附上gcc调用参数及文件核心内容：源码 -> *.c -> *.i

　　//XDPPro v3.7.4b, PLC XL5E-16

//调用记录arm-none-eabi-*.exe
