Script functions required Need the script syntax to change a part value. The command line to issue to change a part value is: value refdes value. And example would be to change R5's value to 100 you would issue the command: value r5 100 Need to add attribute fields to Read more…
This program demonstrates how you access the Schematic object with an Eagle PCB User Language Program – ULP. dlgMessageBox("Do you want to count the parts?","Yes","No","Maybe"); //opens a dialog box: no matter what you answer it will count the parts. Read more…
This is a demonstration video of PCB prototyping with Cirqoid machine. The video covers entire cycle of PCB production – including milling and drilling the board, dispensing solder paste and populating the board with the components. The machine and design files of the board shown in video are available at http://cirqoid.com/
I have used a ULP ( User Language Program ) called Smash.ulp to smash all the parts on the schematic many times. ULP's by themselves are said to be unable to modify a schematic. Smash.ulp generates a script file named Smash.scr. Inside of Smash.scr you will see something like the following: Read more…
I like simple examples for purposes of learning a programming language. Something that does not clutter everything up leaving me with a million doubts. The following Eagle ULP tutorial file writes an ASCII string to two different files. The first file write demonstrate the default location of file writing and the second shows Read more…
This ULP ( User Language Program ) opens a file dialog automatically using the schematic name to form a file name in the dialog opened. If you want you can change the name in the open dialog box. It is a fairly simple program without all the extra stuff you Read more…
Interesting idea of making a laptop based on an ARM processor occurred to me. I phoned the Center for Internet Research and they lept into action. Research Links Building my own laptop – Bunnie's blog Update on Our Laptop (aka Novena) – including an FPGA Novena Wiki If you have never Read more…
