Detailed Description

STM32 Logger — UART/SWO/ITM-based logging with full BaseLogger interface.

Supports multiple output backends:

• UART (via CubeMX UART handle) — most common for STM32
• SWO/ITM (via ITM stimulus port) — for SWD debugging
• printf (via _write syscall / semihosting) — fallback

Usage

extern UART_HandleTypeDef huart2;
 
StmLogger logger(&huart2);
hf_logger_config_t config{};
config.default_level = hf_log_level_t::HF_LOG_LEVEL_INFO;
logger.Initialize(config);
 
logger.Info("APP", "System started, version %d.%d", 1, 0);
