-
qpcpp
QP/C++ Real-Time Event Framework/RTOS is a lightweight implementation of the asynchronous, event-driven Active Object (Actor) model combined with Hierarchical State Machines.
-
Isn't this the premise upon which Google's Pigweed (https://pigweed.dev/) operates?
-
o1heap
Constant-complexity deterministic memory allocator (heap) for hard real-time high-integrity embedded systems. Allocation takes ≈165 cycles on Cortex M4. There is very little activity because the project is finished and does not require further changes.
-
EmbeddedProto
Embedded Proto is a C++ Protocol Buffers implementation specifically suitable for microcontrollers. It is small, reliable and easy to use.
-
amp-embedded-infra-lib
amp-embedded-infra-lib is a set of C++ libraries and headers that provide heap-less, STL like, infrastructure for embedded software development
-
wide-integer
Wide-Integer implements a generic C++ template for uint128_t, uint256_t, uint512_t, uint1024_t, etc.

hsmcpp
C++ based Hierarchical / Finite State Machine library oriented for embedded and RTOS systems.
