Right mouse clicking a debugger break point in the source code or in the debugger Breakpoints Window (CTR+ALT+B) provides a number of menu items relevent to the breakpoint.
Clicking the debug "When Hit" option opens the following dialog window allowing us to optionally print a message that includes variable data or we can just report variables to the debug tool. Debugger messages can be as long as is needed because they are not compiled into the Arduino program. Messages are stored locally on the pc and displayed when a break or trace point is hit.
The example below shows how to create a dynamic trace message that includes variable data. Note that requests for variable data are enclosed in {brackets}. Any expression that returns a numeric (int, float etc) value is allowed and any number of expressions can be included in the message. The "Run Macro" option will be supported in future versions of Visual Micro. The "Continue Execution" feature is only relevent if "Debug Break/Pause" is enabled.
After making changes to arduino debugger breakpoints or source code the project must be compiled and uploaded. The easiest way is to press F5
If the debug message soley consists of expressions (no text) then a trace message entry is not displayed. The variable/expression inspector shown below will automatically open when a debug session starts.
Double click arduino debugger variables and/or trace message to jump to the respective source code line.
