FreeRTOS is a popular real-time operating system for embedded devices, being ported to 31 microcontrollers. It is distributed under the GPL with an optional exception.
- Designed to be small, simple and easy to use.
- Free RTOS kernel - preemptive, cooperative and hybrid configuration options.
- Includes a tickless mode for low power applications.
- Official support for 34 embedded system architectures.
- Supports the ARM Cortex-M3 MPU.
- Very portable, predominantly written in C.
- Supports both real time tasks and co-routines.
- Mutexes with priority inheritance.
- Powerful execution trace functionality.
- Stack overflow detection options.
- No software restriction on the number of real time tasks that can be created.
- No software restriction on the number of task priorities that can be used.
- No restrictions imposed on task priority assignment - more than one real time task can be assigned the same priority.
- FreeRTOS Ported to Raspberry Pi. This project provides a very basic port of FreeRTOS to Raspberry pi. It includes a demo application that use 2 FreeRTOS tasks to flash the LED on and off.
- DuinOS. DuinOS is a small multithreading real time operating system (RTOS), based on the FreeRTOS kernel, for Arduino compatible boards.It’s installed as an Arduino core, and currently supports the following AVR processors:
- LPC43XX-FreeRTOS-with-2xLED-Threads. This is example code of using a NXP LPC4337 Xplorer board from NGX with FreeRTOS.It has two LED blinking tasks running at the same time.
- FreeRTOS on XMEGA. port.c and portmacro.h for FreeRTOS to run on any AVR XMEGA
- FreeRTOS on STM32. FreeRTOS demos for STM32F103ZET6 board that include LEDs, Buttons, USART, and LCD.
- FreeRTOS on AVR with external RAM. This project add extra RAM connected to the external memory interface of Atmega128.
- LPC4300 Development Boards with FreeRTOS demo. LPC4350 Dual-Core Cortex-M4 and Cortex-M0 Development BoardLPC4350 is the first asymmetrical dual-core digital signal controller with ARM Cortex-M4 and Cortex-M0 processors. The LPC-4350-DB1 development board consists of the most essential components that you need to start your development.It contains the LPC4350FET256 dual-core controller, USB, Ethernet and JTAG connectors, 4 push buttons + 4 LEDs, 16MB external NOR flash.
- Porting FreeRTOS to MikroC for STM32 M3. This project port FreeRTOSV7.1.1 to CORTEX STM32F107 MikroC Version 2.5.
- Using FreeRTOS kernel in AVR projects. Instructions to run FreeRTOS on AVR Atmega128L, using AVRStudio5.
- Running multiple FreeRTOS tasks on AVR. Let us go further with our example code and add more tasks to our FreeRTOS engine. We already have LED flashing task that toggles LED every second. Additionally we are going to create another task that checks button state. Also we are going to send some information to LCD. As always lets take care of drivers for all of them.
