生产者结构这样写有问题吗？

[gangzi]

请问这样的生产者结构有问题吗，对数据的传输会不会因为内层的循环而延时？比如等内层循环结束，队列中的数据才能能被读？

No problem, the producer should work properly in the inner loop, there will not be any delay. But I am not sure whether your state machine should work properly for you project, you should just run and see the result. Run it , debug it.

And for your question in the image, no, no need to use a shift register at that position.

再麻烦解答一个问题：

labview中 功能全局变量 可以同时读吗

普通全局变量在使用时会复制副本，增加开销，但全局变量可以同时访问，所以可以用来做线程间操作的统一开关

不知道上面这句话，我说得对不对有没有问题

另，两个线程如果要使用一个开关控制两个线程中操作的开始、停止，如果不使用全局变量或局部 变量，有没有别的办法可用？

I think Function Global Variable should not be accessed(either read or write) simultaneous, because it is one thread only.

The second question

I agree with you, and I think the rendezvous and event in synchronize plate would help you to control multi threads
