@mgg1010 cool, I'm looking forward to using your module.

My LCD is not working i.e. there is nothing on the display. All I can do is toggle the back-light.

It's the blue one with "Nokia 5110" above the screen. I've tried all the examples from the tutorials page, SPI baud rate 1000000, also tried with different pins, changed the breadboard and cables and nothing helps.

Any ideas please?

Your method above won't support arguments to the constructor - my code supports zero, 1 and 7 arguments.

@mgg1010 sorry if I'm missing the point, but you can pass as many arguments as you want

exports.constructor = function(foo, bar, baz) {
       return new Date(foo, bar, baz);
}

@DrAzzy the thing is that soldering, rewiring etc is a bit scary for me at this moment :)

Cool, thanks

I believe it's this one https://github.com/espruino/Espruino/issues/63

Just an idea I didn't test, but how about

if (Object.keys(test).indexOf("bar") !== -1) {...}

Would that make sense?

Can I use something like that to power Espruino? The price just doesn't seem right.

Hello, from other posts on this forum I already know that I can power 5V devices simply by connecting them to the VBat (in particular I'm thinking about relay module).

Can I use some 3.3V sensors with Espruino at the same time? And should they be connected to a separate GND line?

Confirmed, the GitHub version is showing the proper path and I can connect to my Espruino. Thank you.

And by the way I am using chrome-stable from google repositories, 34 is out of beta now.

That's correct, it is showing up as just ttyACM3. I'am away from my computer at the moment but later I will try this workaround and report back.

Also speaking about doing the good deeds, supporting the project and so on, it is easy to forget that Espruino board is really a nice piece of hardware and, when compared with these fancy boards, it has pros too.

OK, thank you.

OK so after trying multiple times with all different versions I kind of got it working, that is I'm able to upload 1v60 with a python script. New device ttyACM3 shows up and I can connect with a serial port terminal.

WebIDE still says "Connection Failed" but I guess I can live without it for now.

I just got my Espruino board rev 1.3b and I'm not able to connect with it on a Linux system. Here is what I'm doing.

When I connect it to my computer then all LED's are off. If I hold RST button then blue and red glow dimly. When I do the BTN1 + RST thing then the same lights flash for a second and blue light starts pulsing.

At this point /dev/ttyACM3 shows up in the system so I start the WebIDE and try to flash it with this url: http://www.espruino.com/binaries/espruino_1v60_espruino_1r3.bin
It asks for a serial port and says "Connection Failed" for ttyACM3.

Then I try with the python script (firmware version 1v60/1r3) and it looks like it's uploading. After it's done I hit the RST button and again, all dark, and no devices added in /dev/.
That is what I can see on the logs console just after connecting Espruino:

When I try with the 1v61/r3 from last night then it's a bit different. After resetting the board I have red and blue glowing dimly but again no extra devices is /dev/ and completely nothing on the logs console.

Any ideas please?

I'm not Gordon and I'm not related to Espruino, but I'm using one of these boards (HY-Mini) so let me share my experience too.

For me it means that although they should work just fine, it's not guaranteed and you should not expect them to work i.e. demand a fix if something goes wrong.

From what I can see on GitHub, Gordon is really busy working on Espruino (the software) and there is still so many things to be done that bugs related purely to unofficial boards are of low priority.

And that is the situation we have at the moment with HY-Mini boards. They used to work fine, but then something got broken and current version of Espruino firmware doesn't work. He tried to fix it but it was taking too much time so he is not working on it any more, focusing on the official stuff in the first place (which totally makes sense).

So my advice - if you don't like unpleasant surprises go and get the official board, then in case of any problems you can bet on him.

HY-Mini boards come with these nice LCD's. Can I use one of them (3.2") with Espruino Board?

Very good, thank you

I've got a bunch of USB chargers and it would make sense to me to use one of them to power Espruino. Which parameters should I pay attention to if I don't want to damage anything?

Thanks for the links. Did I get it right that Meteor is not running on RPi and you still need a proper server?

Please give us a shout on this forum if you actually get Meteor working on Raspberry Pi, as I'm very interested in this, but somehow a bit less optimistic :)

Very cool! Meteor is amazing but it's a shame it doesn't work on ARM, just imagine BeagleBone/RaspberryPi with Espruino board

Just out of curiosity - when things like that get fixed, are there any automated tests also being updated so that it's not coming back in the future?

Thanks for your explanations, I will give it a try then.

Sounds cool, would be useful for some general testing. Often I wonder "how does this behave" or "is that working" on Espruino (as compared to standard JS implementations) but then I don't have my board at hand and can't be bothered.

Thanks DrAzzy.

Then I guess I was looking in the wrong places. Probably I should have started by saying that I already got them when I was experimenting with Arduino, and now I just want to re-use these things with Espruino. I'm always getting them on ebay and they come from Asia.

So I have this PIR motion sensor, relay module, IR obstacle detector and in auction description they said it is 5V so I'm a bit scared to plug them in and experiment :)
