学习这篇文章（Simulink中搭建图像的采集与输出模型案例分析，Simulink中搭建图像的采集与输出模型案例分析-电子发烧友网）的时候跌跌撞撞搭完了模块，运行的时候却提示All sample times for this block must be discrete. Continuous sample time is not allowed.

更改信号处理模块的采样时间从-1改为整体采样时间的整数倍，结果OK。

运行效果：

介绍说要采用离散的采样时间，我如下修改后未能OK。

参考：All sample times for this block must be discrete. Continuous sample time is not allowed.这种错误解决办法_小灰灰_的博客-CSDN博客

All sample times for this block must be discrete. Continuous sample time is not allowed.这种错误一般都是前面一个模块产生的是模拟信号，后面一个模块需要的是离散信号，只要在错误的模块前面加一个Zero-Order Hold保持器即可以解决问题。

修改后并不能行。

Try changing the sample time of the cyclic decoder input to 0.1 instead of inherited. This is what worked for me.

实测OK
