All those code pointers use ASCII colors so they stand out better.
You give IDFMonitor a pointer to the elf file and it uses addr2line to find any hex values that are in code space and prints the line in a source file. It makes it super easy to see where the crash occurred, or at least near where it crashed.
You can use IDF Monitor as the console for Arduino, but it doesn't give nearly as useful info. It might give you the line of code for the current PC, but that's usually an abort or assert of something. The problem is that the crash dump generated by Arduino doesn't format it's hex numbers with a 0x at the start and it doesn't seem to dump the entire stack trace.
Is there a similar mechanism to make crash debugging easier on Arduino or is there a replacement crash dump output that is more useful?
