# 1. Abstract

PikaPython is an ultra-lightweight Python interpreter that runs with only 4KB of RAM, zero dependencies. It is ready to use out of the box without any configuration required and easy to extend with C.

PikaPython also known as PikaScript and PikaPy.

It's very easy to bind C function to python module with the help of Pika Pre-compiler.Only write the API of python in `.pyi` and the bindings are autoly generated by Pre-compiler.

# Quick Start

You can use [simulation project](https://pikadoc-en.readthedocs.io/en/latest/Keil%20%E4%BB%BF%E7%9C%9F%E5%B7%A5%E7%A8%8B.html) to quick start without hardware，or use the out-of-the-box develop board [Pika-Pi—Zero](https://item.taobao.com/item.htm?spm=a1z10.3-c.w4002-23991764791.11.37216340XZtYt9&id=738387991209).

The board based on STM32G030C8T6 MCU, only 64kB Flash, 8kB RAM can run pikapython with total peripheral device (GPIO、TIME、IIC、RGB、KEY、LCD、RGB). 
CH340 is deployed to support USB to serial with Type-C USB, support download python script py serial, there are 4 RGB on the board and support the [LCD](https://item.taobao.com/item.htm?spm=a1z10.3-c.w4002-23991764791.12.16f97c58fsLjVk&id=660745643102).

The maximum RAM usage of these demos is only 3.56K, which is 4.56K if the 1K stack is included, and the maximum Flash usage is 30.4K. Refer to the 20K RAM and 64K Flash of STM32F103C8T6, less than 25% RAM and less than 50% Flash are used.

## About the custom extern module ？

In addition to device drivers, developing custom Python modules for MCU is very easy. The following two demos are extensions of the custom module, which developed python interfaces for the ARM-2D image driver library.
