使用Python半自动生成Altium原理图封装

前言

放长假了，想搞点钱，对我而言来钱最快的就是帮别人画原理图PCB图了。

不过画了几天发现一个问题：一直以来都自己画自己的，而现在帮别人画，客户发的很多原理图的封装都没有，基本上每画一个图都要画两三个，碰到一些小的还好几分钟就能画完，碰到一些大点的芯片引脚多的很的，自己画一个（配上电脑拉跨debuff）还要十几分钟，在立创EDA上面找的又经常有错，很是不爽

不过得益于AD高版本可以以成文本形式保存原理图文件，使用程序完成任务也就成为了可能。

历程

随便新建一个原理图以ASCII保存。打开来可以看见这么一份”模板“，

测试放置一个3PIN可以看到多了这么一部分

可以看出

RECORD = 
1：器件开始
2: 引脚
14：长方形（背景）
34：元件标号
41：脚注
44：器件结束
DESIGNATOR：管脚标号

还有像xy坐标，NAME，COLOR等不必多说

接着就是写个python脚本把它们拼起来辣

再生成原理图库复制到自己的库就行了

值得注意的点

1. 在“模板”的头部中，WEIGHT代表着剩余的部件量，如果设置的太小当AD读取完后就不会往下读了，就会导致缺这缺那

1	\|HEADER=Protel for Windows - Schematic Capture Ascii File Version 5.0\|WEIGHT=38

2.同样在“模板”的头部中，第二行中包括了纸张大小等的定义，如果遇到🐞可以适当修改

3.引脚方向依据PINCONGLOMERATE的值，连接方向向右时为56，从此每逆时针旋转90°加一

4.xy坐标必须为不带小数的整数，不然它立马扑街给你看
