OpenWSN firmware: stuff that runs on a mote
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:7 commits, 8 PRs, 7 comments in 1 day
Contributions summary:Peter primarily focused on fixing warnings and potential issues within the OpenWSN firmware codebase. Their contributions involved addressing old-style function definitions, fixing potential uninitialized variable errors, and correcting a bug related to channel hopping. These changes were made across various modules, including low-level drivers, board-specific implementations, and core system components, demonstrating a broad understanding of the embedded system architecture.
