# 1.简介
|
||
|
||
PikaScript 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 ≤ 32KB，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。
|
||
|
||
PikaScript 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。
|
||
|
||
PikaScript 也支持 MDK、iar、RT-studio 等常见 ide 开发，能够轻松地调试 C 模块。
|

|
||
## 使用在线图形化工程生成器
|
||
生成器地址:

<img src="document/image/152632673-019a7f92-7b7f-4fb5-92b7-4ae4c26ec865.png" width="500"/>
|
||
|
||
## 使用 Pika 包管理器[PikaPackage.exe](https://gitee.com/Lyon1998/pikascript/attach_files/907478/download)
|
||
|
||
1. 直接运行[PikaPackage.exe](https://gitee.com/Lyon1998/pikascript/attach_files/907478/download), 自动下载并更新pikaScript主仓库(文件在当前磁盘的/tmp/pikaScript文件夹)
|
||
|
||
2. 将[requestment.txt](/bsp/stm32g030c8/pikascript/requestment.txt)放在[PikaPackage.exe](../../raw/master/tools/pikaPackageManager/pikaPackage.exe)同一文件夹下, 运行[pikaPackage.exe](../../raw/master/tools/pikaPackageManager/pikaPackage.exe), 自动在当前目录下安装[内核](../../tree/master/src)、[预编译器](../../tree/master/tools/pikaCompiler)与[模块](../../tree/master/package)。
|
||
|
||
3. 已发布的模块列表：[packages.toml](/packages.toml)

# 快速上手
|
||
|
||
可使用[仿真工程](document/1.三分钟快速上手.md)快速上手，无需硬件，也可以使用官方支持的开发板[Pika派—Zero](https://item.taobao.com/item.htm?spm=a2126o.success.result.1.76224831Y0X1gO&id=654947372034)，上手即玩。

# 6.内核测试与开发
|
||
|
||
## linux 下测试 pikascript 内核(推荐ubuntu20.04)：
|
||
|
||
step1: 拉取项目
|
||
``` shell
|
||
git clone https://github.com/pikastech/pikascript
|
||
cd pikascript/port/linux
|
||
```
|
||
|
||
step2: 编译项目
|
||
```
|
||
sh install_dependency.sh # 安装依赖，第一次用时运行
|
||
sh pull-core.sh
|
||
sh init.sh # 第一次编译前运行，之后就不用运行了
|
||
sh make.sh # 编译项目
|
||
```
|
||
|
||
step3: 运行单元测试
|
||
``` shell
|
||
sh gtest.sh
|
||
```
|
||
|
||
step4: 运行基准测试
|
||
``` shell
|
||
sh ci_benchmark.sh
|
||
```

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 PikaScript 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）
|
||
|
||
|
||
## 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 pikascript 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。
