Hi,

today i found a strange bug on VisualMicro.

If you try this library: https://github.com/todbot/SoftI2CMaster

on the included Examples, in Arduino 1.5.8 there is no compile error.

Instead on last VisualMicro 1407.10 SP5 - (4th October 2014) there is this errors:

Code (C++)

Makes sense.

I noticed the library missing from the compile and I would have expect a more obvious error.

The way Arduino works is that user libraries are found off the sketchbook folder\libraries.

In Visual Micro you have set a sketchbook folder of D:/DATI/PERSONALE/Varie/Elettronica/ARDUINO/Sketch_Atmel but in the Arduino Ide it is different. 

You can clear or adjust the sketchbook from Visual Micro then re-start the ide and it should use the one set in the Arduino ide.

Thanks

It wouldn't be right for some people that do not use Arduino Ide.

We have to reply on people not entering a value because it says (optional)
