What is it?

"FreeACT" is a minimal real-time embedded framework (RTEF) based on the FreeRTOS kernel. FreeACT implements the Active Object (a.k.a. Actor) design pattern.

This presentation explaining "FreeACT" is available on YouTube in the following playlist:

The material was originally presented by Miro Samek at the Embedded Online Conference 2020

Supported Boards

The examples are provided for the following embedded boards:

• TivaC LaunchPad (EK-TM4C123GXL) (ARM Cortex-M4 with single-precision FPU)

• Pearl Gecko (EFM32-SLSTK3401A) (ARM Cortex-M4 with single-precision FPU)

• STM32 NUCLEO-H743ZI (ARM Cortex-M7 with double-precision FPU)

• other boards coming in the future...

Licensing

FreeACT is licensed under the MIT open source license, which is the same used in FreeRTOS.
