I edited this question, as I originally thought it had something to do with Electron, however after doing this simple test with only node.js, I believe I have narrowed it down to this version of the library on Windows. Once you've got things working, you can install Node-Serialport from source with: npm install serialport -build-from-source. Precompiled binaries are available, but if you want to build it from source you'll need to follow the node-gyp installation instructions. I tested downgrading the serialport library to version 4.0.7 and it does work.ĭoes anyone have any ideas what might have changed between 4 => 6? Node-Serialport supports Windows 7, 8.1, 10, and 10 IoT. Neither the port.on('data') or port.on('error') events are hit. However, when I run it on my Windows 10 machine, I do not get any response at all. While you can read and write at any time (actions will be queued until the port is open), most port functions require an open port. Currently we only ship a Node Stream Interface. This allows you to set up and use multiple serial connections. Interfaces take a binding interface and provide a different API on top of it. All commands must use an index x to reference the connection to a COM port. It includes cross platform and mock bindings for testing. ![]() serialport provides a good set of defaults for most projects with a node stream api. Constructing a SerialPort object immediately opens a port. However it is quite easy to mix and match the parts of serialport you need. ![]() When I run this code on my Mac, I get the expected response. When opening a serial port, specify (in this order) Path to Serial Port - required. In the example project, I am passing in 'V\r' and am expecting the version of the device to be returned. The device I am connecting to accepts an ascii command and the carriage return to terminate that command. I set up the following sample project to narrow down where the issue might be: ![]() configure the connect button and use another thread to listen for dataĬonnectButton.I am using the following library to connect via USB to an external device: PortList.addItem(portNames.getSystemPortName()) SerialPort portNames = SerialPort.getCommPorts() įor(int i = 0 i < portNames.length i++) Window.add(topPanel, BorderLayout.NORTH) JButton connectButton = new JButton("Connect") create a drop-down box and connect button, then place them at the top of the window 00031 00032 include serialport.h 00033 include serialmouse.h 00034. Their base addresses are stored in the BIOS data area at 0040:0000h (COM1) and 0040:0002h (COM2). tDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) MS-DOS support two basic communications ports - COM1 and COM2. } else if (ch >= '0' & ch 0) decimalPoint *= 10 The problem is, that this is hard to debug because I can’t open the serial monitor of the Arduino when I’m communicating with my Java program. ![]() In my Java program I receive the data I send to the Arduino but I’m not receiving any parsed data. If I do the same thing with my Java program, it’s not working. If I test the parsing code of my Arduino with the serial monitor of the Arduino I works fine. The communication between the Arduino and my PC works fine because I can send data in in both directions. To use the programmer in Mac OS X, you will need to determine which names have been assigned to its serial ports. I want to send data (G-code) from a Java program on my PC to an Arduino.
