In the cmsis_os2.c code, IS_IRQ_MASKED is used to determine whether context in interrupt or critical. Returning true will execute the *fromISR function, but in the FreeRTOS description, FreeRTOS API ...

ArduinoライブラリとしてTOPPERS/ASPを使えるようにしたプロジェクトがあります。 このプロジェクトのターゲットデバイスはWio ...

In previous tutorials, we have covered the basics of FreeRTOS with Arduino and the Queue kernel object in FreeRTOS Arduino. Now, in this third FreeRTOS tutorial, we will learn more about FreeRTOS and ...

そろそろリアルなハードウェア上でFreeRTOSを動かしてみたくなったので、M5StickC Plusをポチった。M5StickC PlusにはXtensa LX6コアベースでWiFiやBLEがワンチップ化されたESP32マイコン（Espressif ESP32-PICO-D4）が搭載されている。標準の開発環境はArduinoかUIFlowだけど ...

In the previous tutorial, we introduced FreeRTOS in Arduino Uno and created a task for the blinking LED. Now, in this tutorial, we will dive more into advance concepts of RTOS APIs and learn about ...

If operating systems weren’t so useful, we would not be running them on every single of our desktop systems. In the same vein, embedded operating systems provide similar functionality as these desktop ...

Abstract: We present the design of a multicore version of FreeRTOS, a popular open source real-time operating system for embedded applications. We generalize the scheduling policy of FreeRTOS to ...
