[导读]在STM32软件开发中，ST官方提供两套固件库：HAL（Hardware Abstraction Layer）与LL（Low-Layer）。很多工程师困惑：两者除了API风格不同，运行效率和资源消耗究竟差多少？本文基于STM32F407，对GPIO翻转、UART发送、定时器PWM三种场景做实测对比，并给出工程选型建议。

We've decided to retire and archive this project - there's just no safe way to run Python within pyodide safely with reasonable latency. Instead, we're working hard on Monty which should solve the ...
