Message Filters
Hi,
I'm trying to design a web interface to control canBus using mcp2515. now, i need to set a filter for incoming data which is chosen by user in run time. is there any way to set filters without involving into kcd? if there is none, how should i change kcd in run time? can anyone do me a favor and post an example?
How to send data over CAN?
Can this module be used to send data over CANbus as well ?
If yes, can you post a small example. The example in the readme isnt clear. Also where are the docs hosted ?
Thanks
Request: onClose/onError handlers
node-can doesn't seem to have error and close handlers (unless I'm missing something). It'd be nice to provide this in the module, allowing us to do something if the connection to the bus fails or closes.
When creating the channel, this can be caught using a try..catch, but how would I go about doing after we have a working channel?
Decode/Encoding tests fail
For some reason all the signal decoding tests are failing. Need to investigate.
What type of licensing does this project have
We're considering using this with our open sourced project. What type of license is this intended to have?
Multiplexing limitation: No extended multiplexing support.
The current implementation does not support extended multiplexing.
Extended multiplexing allows defining several multiplexors in a message and a signal can be multiplexed for more than one multiplexor value. A multiplexed signal can also serve as multiplexor signal for other multiplexed signals, meaning that hierarchical multiplexing can be modeled.
-> Extended multiplexing would be a great enhancement but likely requires a little remodeling of the current object structure. That could require breaking changes.
The quote above is taken from the Vector document below, but the kcd file format also supports it:

Network definition file (*.kcd): Doc and generation?
Hi Seb,
where can I find the defintion for the .kcd entries? And is any tool out there to generate an appropriate .kcd file?

How to decode all signals in a message at once?
I want to decode all signals of a message at once based on the kcd information, something along these lines:
"use strict";
var can = require('socketcan');
var fs = require('fs');
// Parse database
var network = can.parseNetworkDescription("GWI_TT.kcd");
var channel = can.createRawChannel("can0");
var db = new can.DatabaseService(channel, network.buses["Private"]);
channel.addListener("onMessage", function(msg) {
console.log(msg);
let message_info = db.messages[msg.id];
if (message_info.id == '3')
{
for (let signal_name in message_info.signals)
{
let signal_info = message_info.signals[signal_name];
// decode that value based on information in signal_info
let value = ???
}
}
} );
channel.start();Any hints appreciated.
Can not read 32bit
Hi,
I tried to read 32 bit but it returns zero. Can you change the test function with below and confirm?
exports['little_endian_decode'] = function(test) {
data = new Buffer([0xDE, 0xAD, 0xBE, 0xEF, 0xCA, 0xFE, 0xBA, 0xBE]);
test.equals(signals.decode_signal(data, 0, 8, true, false), 0xDE);
test.equals(signals.decode_signal(data, 0, 12, true, false), 0xDDE);
test.equals(signals.decode_signal(data, 0, 16, true, false), 0xADDE);
test.equals(signals.decode_signal(data, 0, 24, true, false), 0xBEADDE);
test.equals(signals.decode_signal(data, 0, 32, true, false), 0xEFBEADDE);
test.equals(signals.decode_signal(data, 12, 8, true, false), 0xEA);
test.equals(signals.decode_signal(data, 12, 12, true, false), 0xBEA);
test.equals(signals.decode_signal(data, 12, 20, true, false), 0xEFBEA);
test.equals(signals.decode_signal(data, 12, 36, true, false), 0xCAEFBEA);
test.equals(signals.decode_signal(data, 0, 1, true, false), 0);
test.equals(signals.decode_signal(data, 1, 1, true, false), 1);
test.equals(signals.decode_signal(data, 2, 1, true, false), 1);
test.equals(signals.decode_signal(data, 3, 1, true, false), 1);
test.done();
}Also, tried to fix the return value type, but no luck:
Local<Number> retval;
uint64_t val = _getvalue(data, offset, bitLength, endianess);
// Value shall be interpreted as signed (2's complement)
if (isSigned && val & (1 << (bitLength - 1))) {
int64_t tmp = -1 * (~((UINT64_MAX << bitLength) | val) + 1);
retval = Number::New(Isolate::GetCurrent(), tmp);
} else {
retval = Number::New(Isolate::GetCurrent(), val);
}
info.GetReturnValue().Set(retval);Can ID
Sorry to disturb, but I can not find information which needs to put to the node as "ID number".
I'm using Ubuntu 16,04, and I have the can0 connection. Is it 0 is ID?
Thanks
Moving to `Buffer.from(...)`
new Buffer(...) is unsafe and deprecated. Could the code in these places be changed to Buffer.from(...)?
Unable to install on Windows (target system is Linux)
Hey guys,
I'd really appreciate some help in the following regard.
We're developing on Windows machines but our target will be a small embedded Linux. Communication should use CAN and that's how I stumpled upon this very promising package.
I intended to add a conditional switch in my application: use some sort of CAN-dummy-mock during development on Windows then build it via Webpack and deploy it to Linux where socketcan can be used.
However, when I try to install it using yarn add socketcan I receive the following error:
info [email protected]: The platform "win32" is incompatible with this module.
info "[email protected]" is an optional dependency and failed compatibility check. Excluding it from installation.
error [email protected]: The platform "win32" is incompatible with this module.
error Found incompatible module
I understand that this is due to fsevents needing Linux/OSx to work but is there a way to get it to install anyway and only make use of it on the target system?
Best regards,
Rolf
Multiplexing: Unusual API to send multiplexed messages.
The current implementation requires the user to append a ".[multiplexor value]" to the name of the multiplexed message that he wants to send.
IMHO requiring the user to just set the multiplexor value through the signal API and then call send on the message would be the more natural approach. And it does also work when extended multiplexing becomes implemented.
Not able to install the lastest version
I downloaded the Github version - unzipped it then executed the following commands
- cd Downloads/node-can-master
- npm i
- npm run-configure
- npm run-build
- npm install socketcan
and i get the following error
npm ERR! code ENOSELF
npm ERR! Refusing to install package with name "socketcan" under a package
npm ERR! also called "socketcan". Did you name your project the same

Windows support?
Is it possible in perspective or now use CAN on the windows machine?
Signal type limitation: No support for float/single and double.
The current implementation does not support signals of floating point types single or double.
Extended frames example
I have the following:
Request:
`cansend can0 7E0#0322F12100000000`
Response:
$ candump -L can0 | grep '7E8#'
(1555792813.746362) can0 7E8#037F2278AAAAAAAA
(1555792813.832389) can0 7E8#102162F121313737
Would I need to send the response as 2 messages to the channel? Note how the length byte on the second message is 0x10, which is greater than 0x08 (aren't all CAN messages supposed to be 0x08 bytes long)?
Remote request kills network?
Hi,
I'm using a bog standard MCP2515 based can board to communicate with another device. It seems to get all the data just fine until I get message like this though.
can0 0DFFFFFF [8] remote request
That seems to kill the network and I need to down/up can0 to get it working again until the next remote request. Is there a way to stop this behaviour?
Thanks,
Rob
Signal units not correctly parsed?
var can = require('socketcan');
var network = can.parseNetworkDescription("node_modules/socketcan/samples/can_definition_sample.kcd");
console.log(JSON.stringify(network, null, ' '));yields the following output
....

"endianess": "little",
"labels": {},
"slope": 0.2,

"defaultValue": 0,
"bitOffset": 30
},
...
but the kcd file contains a unit

messages are not received when can bus gets into warning state
Hello,
When I send a CAN frame and bus gets in warning state (TX err = 119) the onMessage callback is not launched. I see tx/rx frames with candump but can't handle them with socketcan.
Can you help me guys with this issue?
Thanks.
"TypeError: msg.payload.indexOf is not a function"
Hello, I have this issue as on the picture below:
I am trying to send the Data "4000100000000000" to CAN ID "00", but got this error. Some ideas?
Thanks
Excessive cpu usage?
First of all, thank you for writing this library!
Processing 10k CAN messages per second takes about 40% of the CPU on my fairly beefy laptop ( i7-4710MQ CPU @ 2.50GHz), while the equivalent golang and rust programs take about ~4.5% cpu.
These are numbers reported by htop.
I do expect rust and golang to be faster, but as socketcan is written in C++ so not that much faster. Profiling the code revealed that most of the time (95%) it is in epoll_pwait waiting for work. This might be a lie by the node profiler however, as presumably the process is simply waiting for work.
My question is: Is this the expected overhead from libuv? Or something tunable? Like the poll timeout (currently 100 ms)?
Below are the results of my testing, I've tried to elide uninteresting details, if I elided something useful I'm happy to provide them.
Test scenario (node v10.15.1, ubuntu 16.04, socketcan 2.3.0)
Writing about 10k can msgs per second to the vcan0 using cangen. The test program canjs.js simply just reads those can messages with a trivial handler.
$ cat canjs.js
var socketcan = require("socketcan");
cs = socketcan.createRawChannel("vcan0", true);
console.log("canjs connected");
cs.addListener("onMessage", function(msg) {
// console.log(msg.id);
var a = msg.id;
});
cs.start();Profiling canjs.js reveals that major of the ticks are spent in epoll_pwait

Can Send
I am a rookie at this CAN bus stuff, and in the process I was attempting to create a program similar to cansend in can-utils with this extension. I was able to get a reply message as the example program shows, but have not yet found a way to send my own hex value through the function, or find a way to hard code a value to make sure that it is working. Any help to do this would be greatly appreciated.
npm install socketcan fails
Hi!
While trying to install via npm install socketcan it fails for me.
I updated to latest nodejs but still didn't help.
I noticed that it during the install complained that it couldn't find the module nan. So I did a npm install nan and after that the npm install socketcan worked.
Could it be that you have forgotten to add nan in the package.json I can only see it under devDependencies and not dependencies. But I'm not to good with how these package.json files work.
Message update on no value signals
Hi !
Following the example to update and send a message :
// Update tank temperature
db.messages["TankController"].signals["TankTemperature"].update(80);
// Trigger sending this message
db.send("TankController");
How could I send a message that as no value that would be defined such as the following in a kcd file :
<Message id="0x00A" name="Airbag">
<Producer>
<NodeRef id="2"/>
</Producer>
<Signal name="DriverAirbagFired" offset="0"/>
<Signal name="CodriverAirbagFired" offset="1"/>
<Signal name="DriverSeatOccupied" offset="2"/>
<Signal name="CodriverSeatOccupied" offset="3"/>
<Signal name="DriverSeatbeltLocked" offset="4"/>
<Signal name="CodriverSeatbeltLocked" offset="5"/>
<Signal name="AirbagConfiguration" offset="8" length="8"/>
<Signal name="SeatConfiguration" offset="16" length="8"/>
</Message>
How to update and send such message if i want to send for example the signal "DriverSeatOccupied" ?
db.messages["Airbag"].signals["DriverSeatOccupied"].update(??);
Many thanks for your help!
Debugging `err: true` on a lot of messages
How can I trace back what is causing so many CAN bus errors?
Signal length limitation: No support for signals that exceed 32 bit width.
The current implementation of e.g. EncodeSignal assumes the signal to fit into a 32 bit (u)int type. The Vector dbc format allows signals of up to 64 bit for non FD and 512 bit for FD.
Multiplexing limitation: Current restrictions to the multiplexor.
The current implementation is a simplification of the Simple Signal Multiplexing described here.
It is simplified in that the multiplexor signal is assumed to be in the first byte of the payload. The multiplexor signal should be as flexible in positioning and length as any other signal. Further, I think its value can also be of one of the usual four suspects (signed/unsigned/single/double).

I am running the example from the README and running into an issue.
It looks like the code is expecting db.messages to be a map, but mine is a long array with many null fields, and the message descriptions as JSON objects in the array. It appears to be an issue with the parser, since I can get the example working by doing the following (excuse the this as this is in a class method):
this.network = can.parseNetworkDescription(
"node_modules/socketcan/samples/can_definition_sample.kcd");
this.channel = can.createRawChannel("vcan0");
this.db = new can.DatabaseService(
this.channel,
this.network.buses['Motor']
);
this.channel.start();
this.db.messages.find(m => m && m.name == 'Emission')
.signals['Enginespeed'].onUpdate(s => {
console.log('Enginespeed', s.value);
});
this.db.messages.find(m => m && m.name == 'Emission')
.signals['Enginespeed'].update(80);But obviously this is not the intended API.
Not parseing consumers correctly
According to the KCD specification here the consumer is part of the signal not the message itself. Therefor parsing of consumers is not done correctly.
How to create obervables using channel.addListener?
Hi!
I would like to create observables for channel.addListener('onMessage', cb). Do you have some example code? Mine failed silently
var observableMessages = Rx.Observable.fromEvent(channel.onMessage);
var subscription = observableMessages.subscribe((msg) => {
...
});node-can issues error in building on (node v11 and node-gyp v3)
I'm new to node environment. I wanted to have a can node (for transmission and reception of simple can frames) in node-red which is on raspberry pi-3B.
I tried to install a node from palette from node-red, as per mentioned in:
(https://flows.nodered.org/node/node-red-contrib-canbus)
But installation failed.
So i tried installation with terminal command and faces build errors.
(Note: I am working on node v11.9.0 and npm 6.5.0.)
I guess it is related to version 8 node. Here is the terminal window details:

Change 'associative array' to Object or other Datatype
In socketcan.js you are using a associative array for the signals. Why don't you use it as a normal array or why don't you use a Object?
`/**
* Named array of signals within this message. Accessible via index and name.
* @Attribute {Signal} signals
* @Final
*/
this.signals = [];
for (i in desc['signals']) {
var s = desc['signals'][i];
if (this.signals[s.name] && this.signals[s.name].muxGroup) {
this.signals[s.name].muxGroup.push(s.mux);
} else {
this.signals[s.name] = new Signal(s);
}
}`
Support Node >8
Hi,
i have problems installing node-can with npm when having a Node Version greater than 8.
Is there a trick or am i doing something wrong?
I tried 'npm install node-can' command on a linux machine and got errors concerning to 'make'.
My error pretty much looked like in
#52
Channel start from zero?
I'm using node-can in my project and it works good.
But can the time stamp start from zero when channel start?
Like can-utils they can type candump -tz can0 to get CAN message from zero.
Keeping track of features to add.
Hello @sebi2k1,
I was wondering how you would like to keep track of features that wait for implementation. Should we add a new issue for each observation that might get addressed in the future?
What I have noticed so far:
- Multiplexing support is limited in that only one multiplexor can be present in a message
- Multiplexing support is limited in that the multiplexor signal is expected to be of length 8 at position 0
- Maximum signal length supported appears to be 32 bit
- No floating point support
I know a nice dbc file to test these enhancements when they have been implemented. The lab power supply manufacturer ElektroAutomatik uses e.g. 16 bit big endian multiplexors for 32bit floating point nominal values (e.g. device nominal current, etc.). They provide the dbc files for their units free of charge and they can be converted to kcd e.g. by the Python package cantools.
I cannot contribute right now but I thought I make a note for future me (and perhaps you :).
ElektoAutomatiks dbc files
The fantastic cantools Python package
64 bit
64 bit signal not working because use int 32 bit.
in signal.cc work around for method _setvalue
uint64_t m = ~0 & ~(1ULL << bitLength);
if (bitLength == 64)
{
m = ULLONG_MAX;
}
but for NAN_METHOD(DecodeSignal) I don't know.....
'onStopped' is not invoked
Hi, the example code as below:
After 1 second timeout, I can see 'timeout' log in the console. But I cannot see 'stop' log in the console, it means 'onStopped' isn't invoked.
Can anyone help me to check and fix this?
var can = require('socketcan');
var channel= can.createRawChannel("can1");
channel.addListener("onStopped", function() {
console.log('stop');
});
channel.start();
setTimeout(function() {
console.log('timeout');
channel.stop();
}, 1000);
Network goes down?
I've been using this library successfully for a while, but recently ive had some odd occurances, if i dont run the node app, the can network is fine, however when running the app, i will suddenly 'kill' my network off, and to get it up i need to do a ifconfig can0 down, can0 up.
When this happens, my software does record can messages that shouldn't exsist on the network, (id 4 and 40 normally) these are not used.
Has anyone else had this problem?channel.addListener("onMessage", function (msg) { var id = msg.id; var message = msg.data.toString('hex'); var datagram = 0; var source = 0; var destination = 0; switch (id) { case 1175421952: /* code removed */ break; case 1175420928: /* code removed */ break; case 1175422976: /* code removed */ break; default: console.log("unknown id: " + id + "\t hex: " + id.toString(16)); console.log(msg); break; } }); channel.start();
I'm not sure why this is going on, and it worked until today fine (no non expected messages or anything)
Generic CAN library question
I have a question regarding the language choice for your CAN library. It is really generic, so it might not fit to an actual issue in here, but what is the reason why you opted for Javascript for this and not Java?
Loopback and routing support?
Hi
I am trying to migrate to nodejs a candump+perl based application with routing cababilities.
I don't understand the following code behaviour... i think it is because of proper loopback support...
var can = require('can');
var ask = can.createRawChannel("ask", true);
var respond = can.createRawChannel("respond", true);
var respond2 = can.createRawChannel("respond", true);
// route message
ask .addListener("onMessage", respond.send, respond);
// Log any message
ask .addListener("onMessage", function(msg) { msg.orig="ask";console.log(msg); } );
// shows messages comming from ask
// route messages from ask to respond
respond .addListener("onMessage", function(msg) { msg.orig="respond";console.log(msg); } );
// show messages comming from respond channel, but not routed ones
respond2 .addListener("onMessage", function(msg) { msg.orig="respond2";console.log(msg); } );
// show messages comming from respond channed, included routed ones.
ask.start();
respond.start();
respond2.start();NODE_MODULE_VERSION mismatch
I tried using electron and socketcan/node-can. When ever i try to run the app, that following error message appears:
A JavaScript error occurred in the main process
Uncaught Exception:
Error: The module '/home/user/Documents/01_CODING/myProject/node_modules/rawcan/build/Release/can_wrap.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 57. This version of Node.js requires
NODE_MODULE_VERSION 54. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or`npm install`).

No matter what node version i am using - there will always be a mismatch and i have no clue how to fix it. What i have tried so far:
- removing all
node_modulesand reinstalling - rebuilding
npm rebuild - swapping node versions
- reinstalling node completely
REQ: add a method removeListener
In some context it would be nice to also be able to remove previously registered listeners. Is it possible to add the method removeListener to rawChannel?
node-can fails to build on node v10
I recently upgraded to node v10.4.1 (npm 6.1.0). When building the module, a build error occurs that seems to be related to changes in v8.
