embassy-rs/embassy
May 2023 - Jul 2023
Modern embedded framework, using Rust and async.
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:8 reviews, 1 PR, 11 comments in 1 month
Contributions summary:Carl focused on implementing and improving clock configuration features for the STM32G4 series microcontrollers within the embassy-rs/embassy embedded framework. They added support for the Phase-Locked Loop (PLL) functionality, allowing for more flexible clock settings. Furthermore, the user incorporated Vcore boost mode and Flash wait state configuration based on the PLL output frequency to optimize performance. They also made minor improvements in comments for better clarity and code readability.
