怎么使用示例HTML按钮？

MLA？和谐？CPU？

    MLA?
Harmony?
CPU?

感谢响应我正在使用PIC32以太网启动套件与PIC32 MX795F512L处理器。

    Thanks for responding
 
I am using the PIC32 Ethernet starter kit with the PIC32MX795F512L processor.
Harmony V1.10
 

我不知道我从哪里得到演示网页，但它可能已经是V2012-04-03。它老了，但仍然有效。我有自己的索引页，稍微更改了XML文件和Java文件。只是为了了解它是如何工作的。谢谢你的回应

    I am not sure where I got the demo web pages from but it may have been V2012-04-03. Its old but it still works. I have my own index page and have changed XML file and Java S file slightly. just to learn how it works.

和声演示有AJAX读取PCB按钮并设置PCB发光二极管。看看Wi-Fi演示。



      以下为原文

    The Harmony demo has AJAX to read the PCB buttons and set the PCB LEDs.  Look at the Wi-FI G demo.

好的，但是我认为这将是标准的微芯片演示页面，它显示上下箭头指示PCB板上的按钮是否被按下。我想走另一条路，把按钮放在我的网页上，打开PCB板上的ON/OFF输出。我可能是错误的，稍后我会看到下面的一些HTML代码。&按钮类型＝“按钮”ID =“Mybtn”OnClutl=“MySyfMeple（）”。试试It & /Butt & gt；& lt；p id＝“demo”& gt；& lt；/p& gt；& & t；Script & gt；函数MyMyFror（）{var x＝文档。ID（“MYBTN”）；x.Babid＝TRUE；}



      以下为原文

    OK, but I think that's going to be the standard Microchip demo page which shows up/down arrows indicating if buttons on the PCB board are pressed or not. I want to go the other way and put buttons on my web page to turn outputs on/off on the PCB board.  I could be wrong and I will look at the again later but I was expecting to see some HTML code that looks like this below.
 
Try it

 

您可以通过在计算机上安装基于PC的Web服务器来测试这一点，我使用XAMPP，并从上一篇文章中提供Web页面。如果您打开浏览器上的网页（类型127.0.0.1/xxx，如果Web服务器与浏览器处于同一台计算机上），则在文本框中填写两个值，然后按下按钮，您就可以在Web浏览器调试器上看到JSON。你应该看看屏幕截图。从浏览器发出的JSON字符串显示在“源”标签下。



      以下为原文

    You can test this out some more by installing a PC based web server on your computer, I use xampp, and serve up the web page from the previous post.  If you open the web page on you browser (type 127.0.0.1/xxx if the web server is on the same computer as your browser) , then fill out a couple of values in the text box, and press the button you should able to see the JSON on the web browser debugger. You should see something like the screenshot.  The JSON string that is sent out of the browser is shown under the "Source" label.

获取JSON字符串的嵌入式代码和处理它应该看起来像下面的代码。这是为一个旧的MLA栈编写的，和声的东西可能是不同的。这也是一个例子，完全未经测试，并不是很好的代码。我引用了一个“手动”的JSON解码方法，但是在嵌入式端解码JSON的最好方法是使用一个库，CJSON是最容易使用的，但是它相当大，并且使用了很多MalCoS。我使用的JSMN非常小，但使用起来有点棘手。



      以下为原文

    The embedded code to grab the JSON string and process it should look something the code like below.  This is written for an old MLA stack, the Harmony stuff may be different.  Also this is a example, totally untested and not very good code.  I inlcuded a "manual" method of decoding the JSON, but the best way to decode JSON on the embedded side is to use a library, cJSON is the easiest to use, but its quite large, and use a lot of mallocs.  I use jsmn which is very small but a little trickier to use.
