Hi,

Please confirm where in the code you have breakpoints, what the "When hit" is, which serial port you are using and if you have altered the speed in the project properties to match your sketch code

Thanks

Oh I see.

1st thing is to change your Ide locations and use the Teensy entry instead of Arduino 1.0.x. One of the reasons for the teensy option in the list is to prevent the device message in atmel for teensy 3 boards.

2nd thing

Your code sets the serial port to a speed of 9600. The debugger defaults to 115200 and you will see this in the serial monitor. Normally I would expect the debugger to fail if the speed is wrong. The way to tell the debugger the speed you want to use is to set the RemoteSpeed project property http://www.visualmicro.com/page/User-Guide.aspx?doc=Debugging-With-Different-Por...

Having said this something at the back of my mind tells me that Teensy ignores any serial speed settings and does it's own clever thing so maybe the previous statement is for Arduino users. I don't have time to test this right no but the result in normal Arduino use for certainly be no data.

Lastly

When it freezes can you please upload a screen shot. 

Out of interest have you got continue execution checked on the breakpoint "when hit" window? Are you expecting to break or trace?

Thanks

Please switch on tool>visual micro>verbose messages

Then compile and upload a debug version

After that please zip and email the following two sets of files

1) The files from your sketch folder including any sub folders (such as the visual micro) folder
2) The files from the build folder shown in the compiler output window.

This will save me asking lots of questions.

Thanks

ok thanks
