kandi X-RAY | serialport Summary
Connect to serial port with PHP. Inspired by PHP-Serial, I simplify it and include composer.json to install via composer. Actually, it works on linux. This library is suitable for working with Arduino.

QUESTION
I'm currently reading in data via a SerialPort
connection in an asynchronous Task
in a console application that will theoretically run forever (always picking up new serial data as it comes in).
I have a separate Task
that is responsible for pulling that serial data out of a HashSet
type that gets populated from my "producer" task above and then it makes an API request with it. Since the "producer" will run forever, I need the "consumer" task to run forever as well to process it.
Here's a contrived example:

I keep getting the statement "do not save non-serializable variables in your state" in almost every google search result - But what happens when I really should?
Progect: I am building an app for deviceS connected via SerialPort (using SerialPort WebAPI). I wish to save the connection instance since I use it throughout all my application and I am honestly tired of passing the instance down and up whenever I need it without react knowing to re-render data and display new data - which is important for me too.
Steps that I have done:
It was easy to ignore the non-serializable error using
serializableCheck: false
:export default configureStore({

ANSWER
Answered 2022-Jan-11 at 13:15Simple: don't put it into Redux. Redux is made for data, not for arbirtary external libraries/dependency injection.
If that value will never change after initialization and you do the initialization outside of React, just put it into a global variable that is exported.
If that value will change over time, you should use the Dependency Injection mechanism of React for it: Context. This is really what context is made for - not sharing state values, but global dependencies.
QUESTION
I am trying to build a plugin for a Minecraft Spigot server that ultimately I would like to be able to communicate over serial with things connected to my PC (server is running locally on the PC as well).
I have been able to build and run the plugin and manipulate player/blocks in the game so I know the build process for my base plugin is working. My trouble started when I began trying to include an extra dependency: jSerialComm
I added the dependency entry in my pom.xml file:
...ANSWER
Answered 2021-Dec-31 at 16:46Even if the JAR is present in your plugin, the classes of the JAR are not loaded in the classpath and Spigot cannot access the classes.
You can use a plugin, such as the maven-shade-plugin, which copies all classes from your API-JAR to your Plugin-JAR.
First, set the scope from provided
to compile

A host rule can span multiple hosts.

I've been trying to read serial data from a Feather M0, but for some reason I can't read the data into a buffer. This device is for sure outputting serial data, and both PlatformIO and the Arduino IDE show serial data in their respective serial monitors. However, it will timeout when I'm reading it in Rust, every single time, no matter what timeout value I have it set to. Here is my code:

QUESTION
I'm trying to figure something out here
I have a 'sequence' to be executed via a serial port (on an RPI).
I have an supervisored PHP command in Laravel running that connects to a MQTT broker.
When I send a message to that broker, the RPI picks it up and processes it. Now, I have a moment in which I wait for user interaction. The issue here is, sometimes the user does not interact with the system and the PI keeps "waiting" for serial data. When a user presses a button, I get serial data, which I can process.
I tried to use a while (true) {}
loop that reads the serial data, but it just stops suddenly. Here is some example code;
ANSWER
Answered 2021-Dec-05 at 12:15If you look at the source of lepiaf\SerialPort you'll find it sets the stream in non blocking mode, however the read method does an infinite loop until it finds the separator. This means it will never return unless the separator is received, and depending on your configuration your script will be killed once the php max execution time is reached. Since the library is very simple the better option is to edit the read method adding a timeout parameter. Edit the file "lepiaf/SerialPort/SerialPort.php", scroll down to the read method (line 107) and change it as follows:

Install serialport
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
