Cubesat Space Protocol - A small network-layer delivery protocol designed for Cubesats
Role in this project:
Back-end Developer
Back-end DeveloperContributions:1 release, 217 reviews, 215 commits in 1 year 5 months
Contributions summary:Yasushi primarily contributed to the codebase by addressing build errors and inconsistencies within the Cubesat Space Protocol library. Their work involved modifying source code files to convert data types, correct merge conflicts, and remove obsolete options, particularly focusing on adapting the code to work across different operating systems and build systems like Meson and Waf. The user also added meson build instructions and removed unused header files. They also made changes in the source code of the can interface and interfaces and drivers usart and udp to handle with different OS.
