This will add 2 include lines into your program.Īdd call to function debug_init to your setup function. The avr-debugger library should appear in the list. Type avr-debugger into the Filter your search… box. In VS Code, open Command Palette ( F1) and type Arduino, then select Arduino: Library manager. Restart VS Code if it is now running so that the new library is loaded. In this repository, find the folder from avr_debug/arduino/library and copy it into the Documents/Arduino/libraries. You should now have Documents/Arduino/libraries/avr-debugger folder.Īlternatively, you can download (or clone) the repository from github –. Just extract the avr-debugger folder into your Documents/Arduino/libraries folder. Step 1 – Install the avr-debugger Library We will use an Arduino library called avr-debugger which I created to make it easier to use the debugger. So in this article, I present a simple tutorial to make the debugging available in VS Code. Recently, I found out that Visual Studio Code IDE could be used instead of eclipse to make things easier. It works fine, but it requires quite a bit of work setting up the environment. The article is about using the debugger in the Eclipse IDE. Some time ago, I wrote an article about software debugger for Arduino Uno which works with the GNU debugger – GDB. For more information on debugging options for Arduino, please see my older article here on Code Project. In practice, there is a way, which I want to describe in this article. These boards don’t have support for debugging and in general, it is not possible to debug the code in these boards without buying an external debug probe. There is no support for debugging the popular AVR-based boards like Uno, Nano or Mega in the Arduino extensions. The debugging they are talking about is only available to a few boards (e.g., Arduino M0 Pro) which include hardware debugger interface on the board. There is a ‘Debugging Arduino Code’ chapter in the documentation for the VS Code Arduino extensions which can be a bit misleading. One thing I should make clear first – this article is about debugging Arduino Uno, Nano, Mega (and possibly other boards based on the AVR microcontrollers). For part three which deals with improving the debugger by using custom bootloder see here. For part one which deals with setting up the VS Code to build Arduino programs, see here. This is part two of a three part series of articles on creating and debugging programs in Visual Studio Code.
