I should know this, considering I write TS exclusively at work 🤦‍♂️
I'm sure there is something really silly and basic I'm missing from it but I'm kind of a noob in Typescript and Electron as you can see.
@rwaldron sorry to bother you again with this but what does
pause() actually do? I'm trying to plot a real-time plot with Plotly and when I use pause() it resets the plot. It does pause the reading but the unwanted effect is that I now need to save the plot data before hitting pause() so that it doesn't disappear, but stays there frozen instead.
Btw thanks @reconbot:matrix.org the
as any cast worked fine :)
@lucas-sg I've published v2.1.0 which now has
pause() and resume() on everything that's an event emitter!
Your handlers won't be called until you
resume(), which takes the object out of the weakmap and sets _events = ...
Can you share your code?
@dtex Thx for your reply, I believe I did what you suggested, however now i’m getting a new error and I posted it in the Arduino forum here:

I’m getting this error when I run my script:

>> 1637373598958 Device or Firmware Error A timeout occurred while connecting to the Board.I’ve checked the troubleshooting instructions on:
https://github.com/rwaldron/johnny-five/wiki/Getting-Started#trouble-shooting
But, I’m still unable to fix it after installing StandardFirmata. FYI- I’m using an Arduino clone (CH341)
Am I on the right track? Any advice would be much appreciated.
Also sorry for not responding the previous message @rwaldron . I left that part of the project to a colleague, I'll let you know if I have more questions regarding the usage of
pause() :)
It’s not a difficult upgrade but I’m not sure you could just provide an open port to j5
I think maybe You could make a serialport object and open it and then give it to j5, but since it depends on serialport I’m not sure how the versions interact
J5 uses serialport under the hood, but when you make the board object you can give it a serialport
I’m not sure if it can take a v10 port the api didn’t change much but it did change
If you don’t give it a serialport object it makes one. (It might call it a transport you’d have to check the docs. im cooking dinner)
board = new Board({
repl: false,
debug: false
});
That's the old code
And this is the new one:
board = new Board({
port: new SerialPort({
path: "/dev/tty.usbserial-1410",
baudRate: 115200
}),
repl: false,
debug: false
});Changing the subject to a more J5 focused discussion I'm getting the following error:
1646263818699 Device or Firmware Error A timeout occurred while connecting to the Board.
Please check that you've properly flashed the board with the correct firmware.
See: https://github.com/rwaldron/johnny-five/wiki/Getting-Started#trouble-shooting
If connecting to a Leonardo or Leonardo clone, press the 'Reset' button on the board, wait approximately 11 seconds for complete reset, then run your program again.
code: 'ERR_UNHANDLED_ERROR',
class: 'Device or Firmware Error',when testing my board's connectivity
I did reupload the StandardFirmataPlus firmware through the Arduino IDE
I don’t know what the current default baudRate is
You can probably find it in the j5 source
I think you’re on the right track
Any idea of how I might learn to interpret the data that I read from the serialport I opened? I'm using an Arduino Mega 2560 and want to read the distance from the proximity sensor connected to it. When reading the data of the "data" event I get a buffer object whose data I don't know how to interpret.
I was trying to see if I could add serialport@10 to j5 so I tried to test the project running simply 'grunt' but 11 tests failed without me even having updated serialport or any other package.
The errors are throwing up in
The errors are throwing up in
test/board-connection.js:9:5, test/board-connection.js:17:5 and test/board.serial.js:13:18 with the error message TypeError: Cannot stub non-existent own property list. Any idea of what I might be missing?
Hi, does anyone have an idea of how to put the
close event of the Board object to use? I've created a Board object, I'm able to communicate with it and I've added a callback function for the .on("close", () => { ... }) event, but I'm not seeing the callback being called after I disconnect from the USB port.
