前言：
而今同学们对“信捷plc编程软件教程”大概比较关怀，同学们都需要了解一些“信捷plc编程软件教程”的相关资讯。那么小编同时在网络上收集了一些对于“信捷plc编程软件教程””的相关文章，希望看官们能喜欢，大家快快来了解一下吧！信捷PLC编程软件XDPPro，里面有arm-none-eabi的gcc程序，测试所用型号的SOC为ST的Cortex-M7。用C语言编程的自由度很高，如果有能力接管编译过程，各种高级数据结构更是锦上添花。
初步测试了GCC的调用过程，从抓取到的一些信息看，用户手册中未详述的魔术操作，在源码中反而直白明了。
如果利用C语言开发出实用的数据结构和算法，这种小型PLC的应用场景还是很多的，毕竟有1MB的程序空间，要填满真不容易。附上gcc调用参数和文件核心内容：源码 -> *.c -> *.i
