my node version was
4.2.1

test.js and testSync.js produce the same output

Error: Cannot find module './out/NodeImu'

auron89

I 've followed all the steps from the library

I get this error
Error: Cannot find module './out/NodeIMU'

but I must say I have not installed Node.js by apt -get it from another source.

calculating that the positive and negative can not be manipulated by code but I should make a circuit and is not convenient according to this configuration as understand what are the pin to switch off ? //16 x 2 display var lcd = new Lcd({ rs: 12, e: 21, data: [5, 6, 17, 18], cols: 16, rows: 2 });

I'm a nuisance!
you know if you can remove and put on the backlight by code?

auron89

thank you all!

auron89

ok this works well .
so let's say in javascript for this type of characters you do not use the " 0 " .

Thank you all

auron89

hello to all
I tried all characters clearly without the space between the ' / ' and x .
Unfortunately, no symbol is displayed properly ..
I would like the opportunity to color a square at a time so I can create the shape that I want ..

I tried to print \ xb0 on display but prints this : " - " instead \ 0xDF printing another symbol incomprehensible ..

auron89

then look tonight I try to print the symbol on display at the weekend I try to incorporate that piece of code in my application unfortunately I am not yet very expert..devo paste this right? var lcd = new LCD(); // Creat an LCD instance. // This is the interface between application and LCD var lcdCo...

hello ! let's say you can not print the two lines , I removed for the time being some printing features on display to prevent from overlapping ... I understand that the command should be asynchronous but should also be run with the setCursor .. by the time I left off . I was trying the method that t...

auron89

I have another question ..to make symbols like this ? " ° "
or other ?
on display do not print correctly if this step directly as a string ..

Good evening everyone. I configured my raspberry as a wifi access point , now I wish that when I connect with my smartphone to open the browser with a welcome page . I state that I have already created the web server to retrieve it but now I write the ip . I wanted to automate the thing ... how can ...

auron89

The fivid method s works well I added only a comparison with " undefined " in print method . I have yet to try the other did not have much time , unfortunately, but I hope to do so soon Now the problem was created with the asynchronous node of js . I have several functions that go to write on the sa...

auron89

thanks I can just try both codes and cause you 'll know!

auron89

I can easily write on the screen all I want ... the problem is if I send two scriptures together you place under the piece of problematic code function lcdPrint(text,row){ var number=text.length; if(number<16){ var missingchar=16-number; for(var i=0;i<missingchar;i++){ text+=' '; } } lcd.setCursor(0...

auron89

thanks for your help.
unfortunately I not think I can create a module working I'll see what I can do ..

auron89

hai risolto?
non ho usato quel modulo ma lo trovo molto carino..
io credo che di default come uscita video sia usato HDMI e non rileva in automatico il connettore...

auron89

thanks for the reply, you have centered the problem ..

It is suggested to change the source module ,
or try a different form , if any?

auron89

I unfortunately do not know if you will have to print one line or two so I can put an event that awaits the end of the previous print..because printing may not be done

auron89

you use the form that you have indicated , I do not know why is not properly documented , the documentation here is slightly clearer , I am using a 16x2 display http://thejackalofjavascript.com/rpi-16x2-lcd-print-stuff/ Meanwhile, I do not understand why in the official documentation does not list a...

auron89

sorry for the question that I find the documentation node node js poor ? I am using an LCD display with the LCD module . It works well. the problem is that being asynchronous I will cross my writings ( the 2-line display ) and he writes everything on the line below. if i use lcd.once('printed', func...

Massi perchè dici "ma proprio no"?potrei aver capito male la documentazione ma l'ho anche provato ed a me a funzionato in questo modo.... il fatto è che io non ho la più pallida idea di dove finiranno i raspberry quindi non posso ne assegnarli ip statici, ne manimolare file di configurazione dei pro...

auron89

mmm allora cerco di spiegarmi meglio. ho fatto è un web server che gira sul raspberry. il web server risponde a richieste http. non mi interessa il funzionamento della applicazione da remoto ma solo nella propria rete locale. il raspberry quando viene collegato alla rete lan o wifi prende un indiriz...
