Free cooperative operating system designed for microcontrollers
Free, simple and tiny cooperative operating system (OS) designed for deeply embedded applications.
Target: ARM Cortex-M, STM8, AVR8.
It was inspired by the concept of a state machine.
Procedure executed by the task (task state) doesn't have to be noreturn-type. It will be executed into an infinite loop. There's a dedicated function for immediate change the task state.
Free real-time operating system designed for microcontrollers
Free, extremely simple, amazingly tiny and very fast real-time operating system (RTOS) designed for deeply embedded applications.
Target: ARM Cortex-M, STM8.
It was inspired by the concept of a state machine. Procedure executed by the task (task state) doesn't have to be noreturn-type. It will be executed into an infinite loop. There's a dedicated function for immediate change the task state.
A simple Embedded System Framework that allows rapid development of applications build for AVR family. System is based on a super-loop architecture with check and skip (no-wait) flag event driver system.
Supports:
UART, SysTick Timer, ADC, SPI, EEPROM, PWM.
Also supports: Xilinx FPGA configuration, FPGA SSI interface, smart card reader etc.
Implementation of virtual threads for the XS-1. Currently a simple context switching implementation for the XMOS XS-1 architecture (Gn, Ln products). Allows a user to run low speed processes on a single thread using time sliced scheduling.
A kernel written by Merck Hung.
IA32 architecture, 32-bit protected mode, Memory paging, Keyboard, Timer Interrupt Handling, and a simple kernel shell to operate.
Written in C language, development under Linux environment.
