What is a .ULP file?
A .ULP file is a special kind of program used with the Autodesk EAGLE software, which is a tool for designing printed circuit boards (PCBs). This type of file is made to add new features or capabilities to the EAGLE software. It's written in a programming language that is similar to C, which is a common language for writing software, but it's specifically tailored for EAGLE, known as the User Programming Language. Along with the code, a .ULP file also includes information about what the program does and who created it.
If you want to look at or change the text and code inside a .ULP file, you can use any basic text editing software, just like you would open a simple text document. This is because, at its core, a .ULP file is just a text file that follows certain rules.
To actually use the program contained in a .ULP file, you need to have Autodesk EAGLE installed on your computer. Within EAGLE, you can run these ULP programs in two places: the Schematic Editor, which is used for designing the schematic diagram of your PCB, or the Layout Editor, where you design the physical layout of the PCB.
In summary, to open and view a .ULP file, you can use any text editor like Notepad on Windows or TextEdit on Mac. But to make use of the program inside the .ULP file, you need to have Autodesk EAGLE, where you can run it in either the Schematic Editor or the Layout Editor.
