# 1.简介
PikaPython 是一个完全重写的超轻量级 python 引擎，零依赖，零配置，可以在 **Flash ≤ 64KB，RAM≤ 4KB** 的平台下运行(如 stm32g030c8 和 stm32f103c8)，极易部署和扩展，具有大量的中文文档和视频资料。
PikaPython 也称 PikaScript、PikaPy。
PikaPython 具有框架式 C 模块开发工具，只要用 Python 写好调用 API ，就能够自动连接到 C 模块，非常方便快捷。不用手动处理任何全局表、宏定义、等等。
PikaPython 也支持 MDK、iar、RT-studio 等常见 ide 开发，能够轻松地调试 C 模块。
