串行通信的Arduino到PHP [英] Serial Communication Arduino to PHP

问题描述

I'm在其中我想通过串行通讯从Arduino的发送传感器数据到PHP的一个项目工作。

I´m working on a project in which I want to send sensor data from Arduino via Serial Communication to PHP.

可惜我不能读PHP串行端口。然而，另一个方向（PHP来的Arduino）完美的作品。
I'm使用 php_serial.class。从雷米·桑切斯PHP ，由RIZWAN卡西姆修改。 I'm依赖从readPort（） - 的功能。

Unfortunately I can not read the Serial Port in PHP. However the other direction (PHP to Arduino) works perfectly. I´m using the php_serial.class.php from Rémy Sanchez, modified by Rizwan Kassim. I´m dependant from the readPort() - function.

I'm有一个Arduino UNO和Apache WAMP - 服务器在Mac OS X工作
我应该意识到没有以太网屏蔽串行连接。在进一步的步骤，我不得不从串口接收到的数据保存在MySQL数据库。
我确实看到一对夫妇涉及这个问题的条目，但他们鸵鸟政策真正帮助我。我曾尝试了这么多。
我敢肯定，有人有一些工作codeS和可以将它们上传。
我究竟做错了什么？
我希望有人将张贴code，或有一个提示！

I´m working with an Arduino UNO and Apache WAMP-Server on Mac OS X. I should realise the serial connection without Ethernet shield. In further steps I have to save the received data from the serial port in a MySql database. I have indeed seen a couple of entries covering this issue, but they don´t really help me. I have tried so much. I´m sure, someone has some working codes and can upload them. What am I doing wrong? I hope someone will post the code or has a tip!

顺便说一句， 是从一个人的视频谁成功了。但我不能得到codeS ....
预先感谢您的咨询！

By the way, here is a video from a guy who succeeded. But I can´t get the codes.... Thanks in advance for your advice!

推荐答案

在php_serial.class.php是种坏了，我不得不去适应它得到一个读出来，这样反而利用读卡器以下方法：
$内容=; $ I = 0;

the php_serial.class.php is kind of broken, i had to adapt it to get a reading out of it, so instead of using the following from the reader method: $content = ""; $i = 0;

                    if ($count !== 0)
                    {
                            do {
                                    if ($i > $count) $content .= fread($this->_dHandle, ($count - $i));
                                    else $content .= fread($this->_dHandle, 128);
                            } while (($i += 128) === strlen($content));
                    }
                    else
                    {
                            do {
                                    $content .= fread($this->_dHandle, 128);
                            } while (($i += 128) === strlen($content));
                    }

我曾经就这

     //trigger_error("reading 0 ".$i, E_USER_WARNING);
     $content .= fread($this->_dHandle, $count);


     return str_split($content);

然后重新构建在PHP中的字节串

then reconstruct the byte string in php
