	Hi I got the debug working with a simple blink program on an arduino uno! Can I take the chip out of the arduino uno and debug from a standalone breadboard? I have several arduino programs running on standalone breadboards, connected to pc via usb (for power and serial com). I don't see why this would not work. I tried late last night and was able to get to the first break statement on the standalone, but not able to move forward in the program. F5 or pushing the start button did not yield any results. When the same chip is in the arduino uno board, the debug works. I am wondering if this is supported. There is no upload capability when the chip is connected to the standalone breadboard. Thanks

	Hi Brad, Thanks for the question. The debugger is very simple and just uses standard Arduino serial. So you are right it will work. I think there is a connection problem with the rx wire from the Arduino/breadboard to the usb cable. When you press F5 all that happens is that Visual Micro sends the 'c' character using the serial. You can try this with the board that works by sending a c instead of pressing F5. When the Arduino is paused at a break point the code on the Arduino is using something like this while (Serial.available()<=0) { //nothing do do, waiting for F5 //delay (5); } Hopefully this gives you enough to find the solution. Thanks

	Tim, I had only wired the communication from chip to usb, because I was only using serial.print functions to see what was happening on the chip. I added the wire for communication from usb to chip and all is working. Cool debugger. Now I am off to remove all the serial.print functions. Thanks! Brad
