Handy tools for development on FujiNet:

• backtrace - given the hex dump strack trace will print the backtrace with source files and line numbers
• search - will search the source code or ESPIDF source for strings
• debug_version.py - embed current commit ID into firmware without modifying repo

To use debug_version.py, add to the [env] section in platformio.local.ini:

[env]
build_flags += !python3 debug_version.py

Also make sure your include/version.h has the _VERSION_H guard:

diff --git a/include/version.h b/include/version.h
index e57ce2b9..62925799 100644
--- a/include/version.h
