Apr 30, 2012  php serial communication in linux. Arduino Forum > Using Arduino > Programming Questions > php serial communication in. I have installed xampp in fedora 13.I am trying to communicate with microcontroller through serial port using php serial class. My code is example.php(find the attachment).On opening example.php through firefox the code is.

This tutorial is meant to demonstrate how to implement a uni bidirectional communication between an Arduino sketch (running on SAM3X Arduino Compatible processor) and a binary application on iMX6 Linux processor. The Arduino sketch will remain the same no matter which programming language you’ll use to develop the binary on iMX6. There are two example scripts for each programming language: C, Java, PHP, Python. You can find the whole repo in. Each program is meant to be executed while the matching Arduino Sketch is running on SAM3X: for the following unidirectional programs: c_serial_example.c java_serial_example.java php_serial_example.php python_serial_example.py for the following bidirectional programs: c_serial_example_bidirectional.c java_serial_example_bidirectional.java php_serial_example_bidirectional.php python_serial_example_bidirectional.py C Serial Libraries for UDOO This part describes how to compile and run the C examples contained in. 1 – Open a terminal and navigate to this folder: cd serial_libraries_examples/c/ 2 – Compile the C file: for c_serial_example.c: gcc -o c_serial_example c_serial_example.c for c_serial_example_bidirectional.c: gcc -o c_serial_example_bidirectional c_serial_example_bidirectional.c 3 – Run the C program: for c_serial_example.c:./c_serial_example for c_serial_example_bidirectional.c:./c_serial_example_bidirectional JAVA Serial libraries for UDOO This part describes how to compile and run the Java examples contained in.

1 – Install the Java library to manage the serial: (NB: jump to the step 2 if you have this example preinstalled in you UDOObuntu distribution, release 1.1 and above) 1a. If you are in a UDOO distribution with the Arduino IDE preinstalled(UDOObuntu 1.0, Debian Wheezy 1.1) use the library contained in the /lib folder(this recompiled library handles properly the /dev/ttymxc3 internal serial of UDOO): sudo cp /opt/arduino-1.5.4/lib/librxtxSerial-2.2pre1.so /usr/lib/jvm/java-7-openjdk-armhf/jre/lib/arm/ sudo cp /opt/arduino-1.5.4/lib/RXTXcomm.jar /usr/share/java/ cd /usr/lib/jvm/java-7-openjdk-armhf/jre/lib/arm/ sudo ln -s librxtxSerial-2.2pre1.so librxtxSerial.so 1b. If you are in other UDOO distributions use the standard Vanilla JAVA Libraries.

I am building an online POS and trying to establish low level communication with an Epson tm-t88iv thermal printer. There is no direct printing of files, only hexadecimals or ascii can be sent to the hardware in a specific format for it to print.

All of this done in a linux enviroment (both ubuntu 13.10 and 12.04). Now the problem is that I can't establish communication with the printer. I have tried using Jzebra and other java to javascript libraries but with no luck, so I changed to a more familiar environment and tried using the php serial class with a status check code but nothing happens. Include 'src/PhpSerial.php'; // Let's start the class $serial = new PhpSerial; $serial->deviceSet('/dev/ttyUSB0'); $serial->confBaudRate(38400); $serial->confParity('none'); $serial->confCharacterLength(8); $serial->confStopBits(1); $serial->confFlowControl('none'); $serial->deviceOpen(); $serial->sendMessage(' x02 x81 x1B x02 x01 x03 x5C x5C'); $read = $serial->readPort(); var_dump($read); which returns an empty string.

Also the printer is not receiving the hexadecimals (it is set on a hex-dump state, to print every hex it receives). I am not sure even if its a coding or hardware problem. I tried installing cutecom to talk with serial port but I don't get any answers either. I also tried doing some stty commands directly from shell but got nothing either.

If someone can please shed a light on why this is happening or if he has any similar experience, it would be great. P. Minitab 17 free trial for mac pro. d: i am connecting using a prolific pl2303 serial to usb cable and its correctly installed as far as i am aware.
