Nov 21, 2015 In my readings about PHP, two important things to know, 1) PHP opens and closes the serial port when it sends something to the serial port, so the arduino auto reset will need to be defeated, and 2) PHP does not have any way to receive data from the arduino via the serial port. PHP Serial I somehow got hold of a « Citizen C2202-PD » point-of-sale display, and I wanted to play around with it. I also managed to get the documentation of it, and created a convenience class to access the serial port though the Linux file.
Posted on in Last time I talked about connecting the Raspberry Pi with the Arduino, I could send simple echo strings from the Raspberry Pi to my Arduino. Great now lets step it up! During research I came across the PHP serial class, a great implementation of serial control for PHP.
Although the class lacks decent support for Windows, it fully supports Linux (and Raspberry Pi). Configuring your Raspberry Pi for PHP serial class Before you can use the class some stuff must happen (I assume you have PHP enabled Raspberry Pi running, there are a gazillion tutorial blogs out there, Google one).

First we need to find out what user runs PHP. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 deviceSet( ' /dev/ttyAMA0 '); $serial->confBaudRate( 115200); $serial->confParity( ' none '); $serial->confCharacterLength( 8); $serial->confStopBits( 1); $serial->deviceOpen(); $serial->sendMessage( ' Hello from my PHP script, say hi back!
'); $serial->deviceClose(); echo ' I've sended a message! N r ';?>First I enable all the errors, the PHPserial class issues warnings on failure and by default they aren’t displayed (in a normal PHP configuration). Then I include the PHP serial class file. Next I initiate a new phpSerial object called $serial and configure some parameters. We don’t have parity, characters are 8 bits and we use 1 as a stop bit.
