How could I debug with my custom arduino board?

Hi
I just start to build my own arduino board from this link http://www.instructables.com/id/How-to-make-your-own-Arduino-board/?ALLSTEPS

I use my atmel-ice to upload to my board via icsp.
My question is how can I watch value in variable of my program via debug ?
Do I need to connect serial pin2 and 3 to PC via FTDI?
Do I need to select board as Uno and specific com port to FTDI above? 

Please tech me, I'really have no idea how to do this Cry

Hi Tikki,

Yes the easiest solution is to follow any guide about making normal Serial.println("Hello world") work in a sketch. This will involve something like FTDI connect to the hardware Serial pins of your micro-controller.

If the hardware serial is not available then you can use other digital pins and instruct the debugger to use the SoftwareSerial library following this guide http://www.visualmicro.com/page/User-Guide.aspx?doc=Debugging-With-Different-Por...

Thanks

Hi I've connect my usb2serial to my arduino board on HW serial pin and then change setting by following your guide in link above.
now that I've some kind of weird problem, In serial monitor if I set speed match to the speed in my code like 9600.
their is not thing show up in monitor window but if I set speed lower than that ex. 4800 it did send some weird character like a symptom when you set the wrong speed.
where did I go wrong?

The default speed for the debugger is 115200, you can change it using the link i posted however in recent versions, if you are using your own serial.begin() visual micro should auto detect the correct speed.

Please confirm the version of Visual Micro you are using from tools>options>visual micro>version>version and verMinor

Thanks

Version is 1.1502.14
Version Minor is 1

Now I change speed to 115200 result is the same only the lower speed will get something if I set to equal speed or faster not thing show up

Hi Tikki,

Can you please switch off "tools>visual micro>automatic debugging"

After doing that you are in standard Arduino mode. Any problems with serial will be caused by hardware or usb issues.

Thanks

It switch off already.

I give a try on arduino pro mini, Just connect it via usb upload code and then the correct data did show up in serial monitor, 

I've change my usb2serial that come with max3243 chip instead of solo ftdi chip and change about 2 of it(luckily I have many of usb2serial) 
Could It be that the problem is come from some incorrect config file?

Hi Tim
I manage to get usb2serial working now.
I've put breakpoint in and also set condition "When breakpoint is hit".
but Expression windows show not thing, where did I go wrong?

PS. Please bear in me if my question is annoying.  I'm very new to this kind of thing also have no background in electronic engineer, Just get start at a very beginning state of learn in arduino

Great and no problem.

Did you switch automatic debugging back on again?

"Tools>visual micro>automatic debugging" needs to be ticked

Then look at the tool bar is that set to "Release" or "Debug". It needs to be set to a configuration with the word "debug" in the name.

Then upload and it should work

Thanks
