PHP – COM poort communicatie

By Sebastiaan Posted on 2019-01-12 Geplaatst in PHP Script

Hieronder vind je een voorbeeld om via PHP met een COM poort te communiceren. Simpel Hieronder een vrij simpele oplossing met FOPEN: (er is een trucje om een compoort hoger als 10 aan te roepen)

<?php

$fp = fopen("COM12", "wb+");

// COM poorten hoger dan 10, als volgt aanroepen:
// $fp = fopen("\\\\.\\COM12", "wb+");

if (!$fp) {
   echo "Niet open";
} else {
   echo "Open";
}

fwrite($fp, "040732090878007800\r");

// of PUTS te gebruiken
//fputs($fp, "040732090878007800\r");

fclose($fp);

?>

<?php

$fp = fopen("COM12", "wb+");

// COM poorten hoger dan 10, als volgt aanroepen:

// $fp = fopen("\\\\.\\COM12", "wb+");

if (!$fp) {

echo "Niet open";

} else {

echo "Open";

}

fwrite($fp, "040732090878007800\r");

// of PUTS te gebruiken

//fputs($fp, "040732090878007800\r");

fclose($fp);

Python Library – PIGPIO

By Sebastiaan Posted on 2016-09-14 Geplaatst in Python libraries

PIGPIO Website Informatie (ENG): pigpio is a C library for the Raspberry which allows control of the general purpose input outputs (gpios). Features

sampling and time-stamping of gpios 0-31 between 100,000 and 1,000,000 times per second.

provision of PWM on any number of the user gpios simultaneously.

provision of servo pulses on any number of the user gpios simultaneously.

callbacks when any of gpios 0-31 change state (callbacks receive the time of the event
accurate to a few microseconds).

notifications via pipe when any of gpios 0-31 change state.

callbacks at timed intervals.

reading/writing all of the gpios in a bank (0-31, 32-53) as a single operation.

individually setting gpio modes, reading and writing.

socket and pipe interfaces for the bulk of the functionality in addition to the
underlying C library calls.

the construction of arbitrary waveforms to give precise timing of output gpio
level changes (accurate to a few microseconds).

software serial links using any user gpio.

rudimentary permission control through the socket and pipe interfaces so users
can be prevented from "updating" inappropriate gpios.

creating and running scripts on the pigpio daemon.
