What is a .PFG file?
The file extension .PFG refers to a type of file known as a jEEPers Program Configuration File. This type of file is specifically used by a software program called jEEPers, which is designed for modifying the programming of AVR microcontrollers. AVR microcontrollers are small, computer-like devices that are used in many electronic applications for controlling processes.
A .PFG file contains detailed instructions that tell the jEEPers program how to make changes to the software running on an AVR microcontroller. These instructions include a base image of the microcontroller's software in a format known as Intel Hex, along with specific modifications or configuration changes that need to be applied to this base image.
The content of a .PFG file is written in plain text, meaning it can be viewed and edited with simple text editing software. However, the code within the file is proprietary, which means it uses a special format that is only understood by the jEEPers program. This proprietary code is processed by what is called the jEEPers scripting engine, a component of the jEEPers software that reads and executes the instructions contained in the .PFG file.
To open and work with a .PFG file, you need to use the jEEPers software. This program is specifically designed to interpret the proprietary code in the .PFG files and carry out the modifications to the AVR microcontroller as specified by the file. Other programs will not understand the specific code and instructions contained in a .PFG file, making jEEPers the necessary tool for anyone working with these files.
