Quantum LeaPs 例程之Blinky

在SOURCEFORGE上下载QP-C、QM和QTools

https://sourceforge.net/projects/qpc/files/

软件的手册见

QM http://www.state-machine.com/qm/index.html

注意：官方建议不要安装到Program Files中

It is generally not recommended to install QM™ in such Windows locations as "Program Files" or "Program Files (x86)", because these directories have access limitations and don't allow you to modify the QM Style Sheet (qm.qss) or new model templates.

我统一安装到D盘中

在系统环境变量中添加QM和QTools工具的路径

创建系统变量 QPC

测试QM是否能正常运行

按照QM™ Tutorial 使用QM创建一个Blinky的简单例程

https://www.state-machine.com/qm/gs_tut.html

打开QM生成的blinky.c文件，下面的代码就是QM根据我们画的状态机自动生成的C代码

调用D:\qp\qtools\bin里边的gcc编译生成可在Windows上执行的blinky.exe程序

执行效果
