About FrameworkComputer/EmbeddedController
This is the official firmware repository for the Embedded Controller (EC) used in Framework Computer laptops. It is a downstream fork of the Chrome EC firmware from Chromebooks, adapted and maintained by Framework for their modular laptops. The repository supports multiple Framework laptop models including Laptop 13 (11th to 13th Gen Intel, AMD Ryzen 7000, Intel Core Ultra Series 1 & 3, AMD Ryzen AI 300) and Laptop 16 (AMD Ryzen 7000 and Ryzen AI 300). Some models utilize the Zephyr RTOS for the EC firmware. The code is primarily written in C (91.5%) with some Python, Makefile, and Assembly. It is open-source under the FrameworkComputer organization on GitHub.
