Hello,

There is plenty of really cool (and cheap!) sensors and modules for Arduino but most of them require 5V. As a complete novice I don't really know how to approach this stuff and I imagine that I'm not the only one.

So do you guys have some good resources/tutorials about interfacing 5V devices with Espruino? Could you share?

That's a bad news I guess... but still thank you for investigating!

Any idea when is that coming out?

Personally I like the fact that it specifically says that the function returned undefined.

In the print("Hello") example above I would be a bit confused about the "Hello" on the console - was is printed? Returned as a string? Or some object? Especially that this behaviour would be different than Node.js or JS console in the browser.

Guys just want to say that this looks really great, I'm sure you will sell more Espruinos just on the looks of this new IDE!

If I could have only one wish - please don't change to some stupidly small fonts like in the current WebIDE.

Also

"""
"HELLO".split();
=["", "H", "E", "L", "L", "O"]
//["HELLO"] expected
'''"

So the last working build was 2014-02-03 (1v49). Next build's binary size was reduced and it looks that something got broken.

Could someone check with his board, please?

I have this board and for me anything after 1v49 doesn't work at all. And I mean not only the display but also the board is not responding at all.

After uploading espruino to the board it doesn't respond on the serial console, I can't write and I don't get anything, just a blank screen.

Gordon HELP :)

Hello,

I'm trying to write a module and I want to make sure that it works properly after it is minified.

Which minifier should I use and with what configuration/parameters to get the same results as in the official build system? I'm not using WebIDE.

@JumJum just to clarify, could you also confirm that in this last case ow.search() is not finding any devices? This info could be quite helpful I believe.

I wonder wich board is @Frida using?

Thanks. Just tried with 1v46 build on 24th January and it works fine, including on ADC/PWM pin. But again, I'm not using the official Espruino board. This can be helpful to Gordon.

Also in your case OneWire.search() fails to find the device so all I know it's not a problem with the module. Unfortunately it doesn't help you much.. :)

@JumJum could you give me the exact version (build date) so I can flash my board with it and see what happens?

Oh and I should have add that I'm using this module for quite a long time now as it's the core for my project and I did not have any issues on previous firmware versions. But then the module itself has also changed in the meantime so it's hard to tell.

Could you also give me the output of `process.env so I can try with the exact same version of firmware that you are using.

@Kim are you loading this module via the WebIDE or is it just copy+paste (the module itself)?

I have just tried with the latest 1v47 build and the example code works fine, but I'm using HY board and not official Espruino.

After uploading the example code could you please try to clearInterval() and then

ow.search();
//should return an array with one quite a big number, possibly negative. That is your device serial code

var serialCode = ow.search()[0];
serialCode - ((serialCode >> 8) << 8);
//should return 40 which is a family code for DS18B20

And sorry for the ugly code formatting, I don't really get how it works on this forum.

If you are using breadboard make sure that the data wire is connected between the resistor and sensor, or in other words that the resistor is not on the way between espruino and thermometer.

This is great! It would be nice if there was a dedicated Tutorials section on this forum to make it easier to find later on. Or maybe even it will make its way into the Tutorials section on the website..

Just want to confirm that the latest build works. Thanks!

Gordon thank you very much for your time. You were right it was a problem with this particular card. Tried with a different one and it works fine. You will get a pull request for a new module soon :)

And to answer your last question: yes, it returns with

=function () {}

I will try to find a different card and try again.

So to sum it up:

• Board hangs whenever I require any module from the terminal with Micro SD card inserted. When it's not inserted then I get:
  > ERROR: Unable to list files : NO_FILESYSTEM
  
• Board hangs only when I require the "fs" module with Web IDE
  

That's the same as with other modules so the cursor goes one line down and terminal stops responding. When I close terminal app and connect again then it is still locked.

When I use other port - the one with Prolific driver - then I can connect to my board but terminal is unresponsive so I can't type anything and I'm not getting any feedback. With older Espruino versions this port works fine.

I have also pinned it down to 2013-12-13 build. That's when problem starts. Build from the night before works fine and it also identifies itself as 1.44 but the file size and file name is different.

ERROR: Using '.' operator on non-object at line 1 col 3
fs.readdir()
  ^
undefined

I should also point out that I'm using nightly build of 1.44 dated at 2013.12.12 as later versions appear to be broken.

Loading existing modules via Web IDE works fine for me but I'm also working on some new modules and I need to test them properly.
I'm using HY-Mini 3.2" with integrated SD card reader. Card is formatted with FAT32 and for test purposes I'm placing currently available DS18B20.js module in /node_modules directory.
Then I try to:

var sensor = require("DS18B20").connect(A1);

After that nothing comes back and terminal stops responding.
Any ideas how to get that working? Should I somehow initialize SD module before I can use it?
