推荐答案

我们怎么知道?
我们无权访问您的硬件图，因此不知道如何将所有内容连接在一起.
您有软件，也有硬件.
试试吧.看看是否有效！

顺便说一句:将来，请在发布代码之前先整理一下缩进-这样会使代码更容易阅读，而不仅仅是发布整个程序-这被称为代码转储，被认为是不礼貌的.
How would we know?
We do not have access to your hardware diagrams and so have no idea how everything is connected together.
You have the software, you have the hardware.
Try it. See if it works!

BTW: in future, please sort out your indentation before you post code - it makes it a lot easier to read, and don''t just post a whole program - taht''s called a code dump and is considered rude.


这篇关于我可以知道，C ++可以为温度和湿度监视系统创建代码吗?该系统使用PIC16F877A，SHT11传感器，蜂鸣器和LCD 2x16.下面的编码是否正确?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
