立创EDA转KiCAD的脚本
增加了对线型等支持 修改了一些bug 目前还在继续改进 打算之后还是增加原理图也迁移
因为老在修改完善 程序也越来越长 我已经上传ghub 大家还是从XXXXXXXXXXXXXXXXXX/m24h/lcEDA2KiCAD 下载吧
.........................................
最近使用了立创的EDA 发现它的元件符号库太全了 尤其是国内常用产品 KiCAD远远不如 那么 有没有可能转它的符号库给KiCAD用
经研究 发现立创EDA使用SQLite3数据库存储其数据 比如个人建立一个元件库 然后从各处找到感兴趣的元件符号 就可以拷贝到自己的库 也就出现在本地存放的.elib数据库中 在表Components的dataStr字段里 格式大致如下
其实也可以在元件编辑器的菜单"文件"->"查看源码"里面得到
或者在自己工程的备份压缩文件里 各元件符号以.esym后缀的文件独立存放
批量导出数据库字段变成文件并不难 我也不多说 也暂时不需要 只是想把工程中遇到的元件加入KiCad的元件库中 因为我大概是购买了 以后也会用的 所以做了一个脚本 用来转换.esym文件为KiCad的.kicad_sym文件 处理文本 当然是perl最擅长 所以用perl

close STDOUT;目前支持引脚 文字 方框 圆 弧 折线 基本够用了 目前测试下来 基本都没有问题
当然 这需要一个个元件加入KiCad 正好顺便检查 批量导入其实大概也有方法的 .kicad_sym文件其实也是库文件 只需要在顶层的kicad_symbol_lib级别下放多个symbol就是了 元件文件就只放一个 至于修改脚本还是后期用copy合并后去掉重复的kicad_symbol_lib头 都不难 但我就不做了
............................... 10.8 .....
更新了脚本 增加了对多单元器件的支持 (比如双运放之类)
顺便 也把从.elib eprj导出所有元件的脚本做了
use DBI;
die "Usage: perl $0 <.elib .eprj file name> \n\tIt will extract all symbols and save them to this directory." if $#ARGV<0;
die "Unable to find '$ARGV[0]'\n" unless -e $ARGV[0];
$dbh=DBI->connect("DBI:SQLite:dbname=$ARGV[0]", '', '', {PrintError=>0}) or die "Unable to connect file '$ARGV[0]': ".DBI::errstr."\n";
$sth=$dbh->prepare("SELECT title,dataStr from components where docType=2 and title is not null and title!=''") and $sth->execute()>=0 or die "Failed to extract symbol data from file '$ARGV[0]': ".DBI::errstr."\n";
while(my @row = $sth->fetchrow_array()) {
$row[0]=~tr/\*\|\"\?\/\\\&;\<\> /_/;
$row[1]=~s/\r*(?=\n)//gm;;
next unless $row[0] && $row[1];
next unless open F, ">$row[0].esym";
print F $row[1];
close F;
}
$sth->finish();
$dbh->disconnect();还包括把多个.kicad_sym文件合并成一个库的脚本 (这样 导出 for %f in (*.esym) do .... 然后再合并 库迁移就OK了)
die "Usage: perl $0 <.output file name or '-' (STDOUT)>\n\t\All .kicad_sym file (which should be created by esym2kicad.pl) will be packed to a signle lib file\n" if $#ARGV<0;

原理图的转换也做好了 代码太长 就不贴了。。。实际上都有修改 代码也都长了 只能提醒还是从GitHub获取最新版。。。如果每次修正都放在这里 这帖子至少得长两页
基本能考虑的都考虑了 包括文字大小 线型 旋转 电源符号的转换 一般不带子框图的基本都没问题了
当然还是需要手工校正一些的

立创EDA就是经常要提示更新还要登账号这一点很反人类，还是AD没这个问题，没有收录到库里边的的符号和封装我一般是直接画的，库文件找一个路径存在本机里就行，若要备份可以考虑用NAS存一份。

毕竟人家是云开发 而且它问题也不少 关键是方便啊 开发到下单速度超快 专业版有完全离线
不过最头疼的是 共享很难做到 而且我看文件数据库 因为考虑团队协作开发 里面有加入参与者的账号信息的可能 虽然我目前个人开发 账号信息是一个公开共用的立创账号 但是也有泄漏什么的可能
而且sch转到kicad也不完美 因为各家都是根据坐标位置重合 来判断连接性的 一种用英式（反而是立创用英式） 一种用国际单位 转换之后因为精度问题 有些时候就对不上
