Blola

Blola is C++ binary logging library for embedded systems.

Library inspired by Trice but has more friendly CLI and no code modifications.

Requirements

• C++ 23
• Some transport for logs (SEGGER RTT integration already implemented)

to use host script:

• Python 3

#include <blola/configured/stdout.hpp>

int main() {
  blog("Hello World!");
  blog("My data: %d", 123);
}

make run-just_log

Strings supported

#include <blola/configured/stdout.hpp>
#include <string_view>

int main() {
  blog("C string: %s", "aboba2");
  blog("std::string_view: %s", std::string_view("view"));
}

Run
