TestStand可以通过以下两种方式调用C语言代码： 1. 在TestStand中使用C语言模块STEP 在TestStand中，可以使用C语言模块STEP来调用C语言代码。可以将C语言代码编译成动态链接库（DLL）或静态链接库（LIB），然后在TestStand中创建C语言模块STEP，将DLL或LIB文件加载到该STEP中，然后将其添加到测试序列中。在测试序列中执行该步骤时，TestStand将调用C语言代码。 2. 在TestStand中使用C/C++插件 TestStand还支持使用C/C++插件来调用C语言代码。使用插件的好处是可以直接在TestStand中编写C/C++代码，而不必将其编译成动态链接库或静态链接库。为了使用插件，需要在TestStand中创建一个新的插件步骤，然后在该步骤中编写C/C++代码。可以使用TestStand提供的API来访问测试序列中的数据和其他信息，以便在C/C++代码中执行所需的操作。在测试序列中执行该步骤时，TestStand将调用C/C++代码。总之，TestStand可以通过C语言模块STEP或C/C++插件来调用C语言代码，具体选择哪种方式取决于应用场景和个人技术偏好。
