RGB Backlight and Rotary encoder

It builds OK in 1.6.10, which is what I have installed. I'll see if I can find out what has changed in 1.6.12.

Must be some compiler option that is different.
"requestEvent" is a forward reference, the IDE used to handle these.
There is a function "requestEvent()" at the end of the file, try moving this function to before the setup() function. That stops it being a forward reference.

I did, same problem occured and the line "Wire.onRequest(requestEvent); // register event" was highlighted.

[MikeB]

I've downloaded 1.6.12 IDE, and I'll install that and see what is happening.
It may be a day or two as I'm tied up with life things at the moment.

In the meantime, try making sure this code is in the file before setup().

Code: Select all

void requestEvent( void ) ;

// function that executes whenever data is requested by master
// this function is registered as an event, see setup()
void requestEvent()
{
  Wire.write( EncoderData, 2 ) ; // respond with Data 2 bytes
}

Mike, the same error happens.
I see several setup()
what i did was replacing the final part of the code with that code you wrote above.

[MikeB]

I've just found time to try 1.6.12 and it compiles fine, even with the original source file.

Please try compiling with the line:
Wire.onRequest(requestEvent); // register event
commented out (put "//" at the start of the line), and see if that compiles.

I must be doing something wrong.
The .ino file is in a folder with the same name on the desktop, should it be in the libraries folder?

[MikeB]

I meant change:
Wire.onRequest(requestEvent); // register event
to:
//Wire.onRequest(requestEvent); // register event

Mike.

[OctavioS]

Option 1: im dumb and not getting it.
option 2: my pc is cursed.

[OctavioS]

Any guess why wont this file compile on my laptop?
I have windows 10 x64. Pretty anoying this subject?

[MikeB]

I think you may have copied the function requestEvent() instead of moving it.
Please try compiling the attached .ino file.

I'm also using Win 10 64-bit.

Mike.

[OctavioS]

I'm working right now. I'll let you know as soon as I can.

Mike everything went fine, thx for your time. now i can go to next step.
