The interpretation process is done in two steps:ДЎ.Read the raw ASCII gerber data,check if thereвЂ™s any error,and put data in different places.E.g.,Extract the aperture definition and put them in Hash tables.HereвЂ™s the list used for storing the raw data:ДЄnd hereвЂ™s the Hash table for storing the aperture information:Дў.Interpret each line and put them in more complex data structures. %ADD57O.030X.040X.015*% вЂ“ D-code 57: obround 30Г—40 mil with 15 mil round holeД02(D2) вЂ“ Exposure off.This is like G00 in GCode,which is rapid positioning.Д03(D3) вЂ“ Flash aperture.Used for exposuring a pad.ДЄfter we figure out what those symbols mean we can start interpreting. вЂ“ depends on aperture type,X to separate each modifier. вЂ“ the aperture descriptions.Standar types: вЂ“ the D-code number being defined (10 вЂ“ 999) HereвЂ™s the quick explanation of the data above.ДЄ line start with F is usually the first line of the file.This parameter is a Format Statement (FS) describing how the coordinate data in the file should be interpreted (in this case, 4.2 format for both X and Y coordinates).ДЄperture parameters definition.Aperture format:ДЄDD вЂ“ the AD parameter and D (for D-code) HereвЂ™s a sample of Gerber code.This snippet draws a number вЂ1вЂ™. The gerber interpretation is developed under вЂњGerber RS-274X Format UserвЂ™s GuideвЂќ.Reading the guide will definitely help you understand the ideal of interpreting gerber files. This post will be mainly explaining the codes I wrote and the ideal behind the codes.I didnвЂ™t upload the codes to my Github since I havenвЂ™t finished commenting the code.Once itвЂ™s done IвЂ™ll opensource the projects.

Reading gerber file is the first problem I need to solve in this software.Currently the software only takes gerber files as input because itвЂ™s a lot of works to support all the EDA softwares.Rather,I only choose to support gerber format,RS-274X to be more specific,because itвЂ™s like a standard format that most of the EDA tools support.However,I only tested the gerber files exported by Altium Designer and it has some problems with files that produced by Eagle,or other tools. :)Д¤.Miscellaneous(Tool bits management,visualization,etc)

This post will focus on these following topics.It really takes time to present each partВ and IвЂ™ll update this post from time to time.So stay tuned if youвЂ™re interested in writing a CAM software.
