Php Serial Extension Free
Data I send to the serial port from the Arduino Uno can be viewed exactly as expected in the Arduino serial monitor, but when reading the data from PHP through serproxy in my WAMP environment I am getting some missing or extra characters (often a character that looks like a question mark inside of a black diamond, for example).
I've found similar questions posted, but all of the answers fell short. Often solutions were given for Linux only, or solved only part of the many challenges it takes to even get Windows to read (not write) from a serial port.
I first tried the php_serial class suggested, but quickly found out it only allows writing on Windows, and the answer for one of the other stack overflow questions (Serial Communication Arduino to PHP) suggested replacement code only for the Linux portion of the code, not Windows.
The article at Serial comm with PHP on Windowsalso mentions limited capacity on Windows for php_serial class and suggests an alternative serial extension (also mentioned here and here), but this would not load on my WAMP environment with PHP 5.4.12 VC9 build when I used the correct matching extension version, added the extension to the correct php.ini, and restarted the server. I received a "Module win_serial is not compiled into PHP" after following all of the steps. If anyone else has had this issue please let me know as I would be willing to look into this again.
Finally, I tried using a program called serproxy which redirects network sockets to and from serial ports. This does work with the caveat that I added a 10uF capacitor on the Arduino's GND and RESET pins to prevent reseting on new serial connections as mentioned at PHP serial port data return from Arduino.
So now, I have my Arduino sending data to my computer via the USB cable, and so long as I am monitoring the data in Arduino's serial monitor, everything looks as it should. The moment I echo out that same data in PHP I begin to see extra or missing data along with the stream. So sending the text "AOK AOK AOK" sometimes becomes "OK?Pz[R" or something similar when echoed out of my PHP script.
Setting parity of serial data. I tried setting it to "EVEN" in serproxy config and DOS (ran command of "mode COM4: BAUD=9600 PARITY=E data=8 stop=1 XON=off TO=on" and recieved a valid response/output that command worked as expected)
Having modified some example socket code for TCP/IP from php.net, I have a PHP script that writes 2048 bits of data from the serial port via serproxy. This page is called via jQuery from another page every 10th of a second and the echoed content is loaded into the contents of a on my main page.
My end goal is to send a stream of either 1's or 0's to be sent to my PHP script to indicate that a should toggle it's background color. I would prefer to be certain those 1's or 0's were not just randomly echoed among the extra characters and truly came from the serial stream itself.
Second, just delay the data on the Arduino side. Apparently the data loss is a "known issue" regarding Arduinos and serial ports. This person's site at martinmelchior.be has some code to delay the data stream being sent from the Ardunio;
Apparently, windows no longer allows to communicate with serial ports via virtual file names. In the case of PHP, I was trying to get in-touch with the com port via fopen("com7"). So this method is no longer viable it seems. This is according to David Gibson. View Source Here . I would love to read more on this if I could find the original source though.
The Web Serial API provides a way for websites to read from and write to a serial device with JavaScript. Serial devices are connected either through a serial port on the user's system or through removable USB and Bluetooth devices that emulate a serial port.
In the educational, hobbyist, and industrial sectors, users connect peripheral devices to their computers. These devices are oft fen controlled by microcontrollers via a serial connection used by custom software. Some custom software to control these devices is built with web technology:
The Web Serial API is asynchronous by design. This prevents the website UI from blocking when awaiting input, which is important because serial data can be received at any time, requiring a way to listen to it.
To open a serial port, first access a SerialPort object. For this, you can either prompt the user to select a single serial port by calling navigator.serial.requestPort() in response to a user gesture such as touch or mouse click, or pick one from navigator.serial.getPorts() which returns a list of serial ports the website has been granted access to.
The navigator.serial.requestPort() function takes an optional object literal that defines filters. Those are used to match any serial device connected over USB with a mandatory USB vendor (usbVendorId) and optional USB product identifiers (usbProductId).
Calling requestPort() prompts the user to select a device and returns a SerialPort object. Once you have a SerialPort object, calling port.open() with the desired baud rate will open the serial port. The baudRate dictionary member specifies how fast data is sent over a serial line. It is expressed in units of bits-per-second (bps). Check your device's documentation for the correct value as all the data you send and receive will be gibberish if this is specified incorrectly. For some USB and Bluetooth devices that emulate a serial port this value may be safely set to any value as it is ignored by the emulation.
After the serial port connection is established, the readable and writable properties from the SerialPort object return a ReadableStream and a WritableStream. Those will be used to receive data from and send data to the serial device. Both use Uint8Array instances for data transfer.
When new data arrives from the serial device, port.readable.getReader().read() returns two properties asynchronously: the value and a done boolean. If done is true, the serial port has been closed or there is no more data coming in. Calling port.readable.getReader() creates a reader and locks readable to it. While readable is locked, the serial port can't be closed.
Some non-fatal serial port read errors can happen under some conditions such as buffer overflow, framing errors, or parity errors. Those are thrown as exceptions and can be caught by adding another loop on top of the previous one that checks port.readable. This works because as long as the errors are non-fatal, a new ReadableStream is created automatically. If a fatal error occurs, such as the serial device being removed, then port.readable becomes null. 2ff7e9595c
