Yes, I was talking about libraries .cpp files.
The reference to global variables does work.
I can set a breakpoint on the ino code and reference a global variable from ReefAngel Class and works just fine Smiley
It didn't find my breakpoints inside any libraries though Sad
I even tried one of the core Arduino libraries and did not work either.
I was trying to add a breakpoint on HardwareSerial.being() function inside HardwareSerial.cpp just to see if it was because of my custom libraries or not, but it seems none are working now. I'll wait for more good news Smiley

Bryan, I received your email thanks and have added the image to your post.

You are certainly talking about debug for .cpp in libraries. That is a neat system you guys are working with!

I have a few tips:

1) I notice you are trying to set a breakpoint on the call to initialise the wire i2c system. I know it is just an example for the picture because it isn't a useful breakpoint but have this information just in case. 

If you want to see what i2c device ids are available when the arduino boots up then there is visual micro debug option called "Startup I2C Report". Enabling this option will give you a list of connected i2c device ids in the debug output windows. 

If you are connecting and disconnecting i2c devices when the arduino is running then let me know because there is a {special variable} name you can add to breakpoints that will give an i2c report at any time during a debug session.

2)

All the classes in the reefAngel:Init should be accessible to breakpoints in the main .ino file.

I guess you can use something like this as a debug message from the .ino:-

Code
Select All
Joystick x pos ={Joystick.x}


Does the main .ino file call something like ReefAngel.Init()? If so then you can add breakpoint conditions to that line (or anywhere after it) such as :-

Code
Select All
The value of joystick x pos ={Joystick.x} and other stuff = {LCD.blah},{TempSensor.blahblah}


The breakpoint message about would result in 3 watched expressions
  • Joystick.x
  • LCD.blah
  • TempSensor.blahblah


And one debugger message

Quote:
The value of joystick x pos =456 and other stuff = 123,456


Or simply debug expressions without a message
Code
Select All
{Joystick.x}{LCD.blah}{TempSensor.blahblah}


Hope this helps for now

Robero. 

Ignore my previous message I posted it before I saw your answer.

Yes we could add debug to some of the arduino core but probably should not. many things can't work until arduino is loaded such as hardwareSerial for debug Smiley

The location you picked for a test is certainly one location that will never work for debug. The debug can't be used before HardwareSerial is loaded  Cry

Yes, I was able to get that part working by referencing global variables, but will there be a way to debug private variables or temporary variables?
For example, I have a for (int a;a<10;a++) inside one of my libraries and I wanted to debug inside this loop. I know I can't do it now, but is it a possibility in the future?

Yes certainly and it makes sense. I just wasn't sure of the audience when I did it originally so excluded the libraries but it seems okay to do this. 

I wouldn't want your fish to die if something does wrong so I try to be careful as possible.   

New users don't know what they are doing, some programs have timing critical functions and the debug certainly can slow things down if you put a break-point in a very fast loop. But I have to assume that people take responsibility for their own actions  Undecided

Would be the cat's meow if it could, as it's usually these type of scenarios that little bugs creep in and can be the hardest to debug. Smiley

Yes, i was just trying to set a breakpoint in a *.cpp class no particular interest in debugging at that particular breakpoint. Tried your suggestions of quoting global variables and it works, will be very helpful, Cheesy Cheesy

I too have found the "Find References" very useful, Roberto's project is very complex and with a click of the mouse I can find where the relevant code is. Smiley

Can't take any credit for it, it is all Roberto's work.  Smiley

Roberto. Wow your ReefAngel project looks like the neatest and most well structured Arduino project on the planet!

Yes it makes me want to get some fish. I have some Koi  but they are really boring.

I would end up killing them so best avoided.

I've been thinking about the debug in libraries. My concerns are probably better understood when considering the copter, plane and drone projects. I have been worried about new users thinking they can place breakpoints anywhere. 

However, having provided the capability to debug .ino and .cpp sketch files I don't think my concerns make sense. I think I am just a worrier  Cheesy

You could make it as a setting in your general options.
Enable disable debug of libraries.

Yes that's a good idea. I think we also need a better disclaimer when the debugging is activated for the first time. Thanks
