# 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。

<img src="document/image/147799764-5db2cb30-ee74-4cde-a2bd-b91c358ae3d9.png" width="500"/>

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。

这几个 Demo 占用的 RAM 最大值只有3.56K，把1K的堆栈也算上就是4.56K，Flash 最大占用是30.4K，以 STM32F103C8T6 的 20K RAM 和 64K Flash 为标准，RAM 才用掉不到25%，Flash 才用掉不到50%。

我们可以简单对比一下 micropython 的常用芯片 STM32F405RG 和这次跑 pikapython 的芯片STM32G070CB

## RAM资源对比

## Flash资源对比

## 参考价对比(以2021年9月11日立创商城10片售价为参考)
![image](document/image/132944757-2b5cfda8-f93f-4456-8d7f-4e4767954056.png)

## 拓展能力如何呢？

除了设备驱动之外，为 mcu 开发自定义的 python 脚本绑定在 pikapython 的开发框架下非常轻松，下面两个 Demo 就是自定义的C模块拓展，这个 Demo 基于 ARM-2D 图像驱动库开发了一些 python 脚本接口。

## 几个小方块~
