Detailed Description

Simple, cross-platform logger for Arduino and C++ environments.

This class provides a lightweight logging facility with support for log levels (ERROR, WARN, INFO, DEBUG), printf-style formatting, and platform-adaptive output (Serial for Arduino, printf for standard C++). It is designed for embedded and robotics applications where monitoring, debugging, and event tracking are essential.

Features

Four log levels: ERROR, WARN, INFO, DEBUG
Configurable minimum log level (messages below this are suppressed)
printf-style formatting for flexible message construction
Platform-adaptive output: uses Serial on Arduino, printf elsewhere
Thread-safe for most embedded use cases (no dynamic memory allocation)
Global logger instance (TRLogger) for convenience

Usage Example

TRLogger.setLevel(LoggerClass::DEBUG);
TRLogger.info("System started, version: %d", version);
TRLogger.error("Failed to open file: %s", filename);
TRLogger.debug("x=%.2f, y=%.2f", x, y);

Methods

setLevel(level): Set the minimum log level
error(fmt, ...);
warn(fmt, ...);
info(fmt, ...);
debug(fmt, ...);

Log Levels

ERROR: Critical errors and failures
WARN: Warnings and recoverable issues
INFO: Informational messages and status updates
DEBUG: Detailed debug output for development

Platform Support

On Arduino, output is sent to Serial (or a user-supplied Print object)
On standard C++, output is sent to stdout via printf
