freertos-sys2

Raw/direct bindings to FreeRTOS functions and types

Principles

1. Support APIs for directly interacting with FreeRTOS APIs and datastructures
2. Keep the build fast and robust

• Right now, this means we don't use bindgen (but bindgen is not totally excluded)

3. Make sure that check can always pass

• cargo check is important for developer tooling. Make sure this always can complete check regardless of features selected (unless they are specifically incompatible) and the rust target used
• Right now, there are no target cfgs or feature cfgs (this can change)

Other freertos bindings that might work for your project

1. freertos-rust
   • Like freertos-sys2, this assumes that FreeRTOS is built seperately and linked in by some external mechanism
   • Unlike freertos-sys2, this binds all FreeRTOS APIs by using stub functions written in C.
   • Unlike freertos-sys2, this provides higher level APIs directly. Does not expose direct bindings to FreeRTOS APIs
2. freertos-sys
   • Unlike freertos-sys2, builds FreeRTOS in it's build.rs script
   • Unlike freertos-sys2, does not export any FreeRTOS specific functions, instead exporting cmsis-rtos2
3. freertos_rs
   • Unlike freertos-sys2, uses shims written in C to interact with FreeRTOS rather than binding the symbols directly
   • Unlike freertos-sys2, does not expose the low level function calls. Only high level abstractions are exposed
   • Like freertos-sys2, assumes that FreeRTOS is built seperately and linked together by some external mechanism.
