Open Source Assembly Embedded Systems Software for Mac

amforth is an extendable command interpreter running on AVR ATmega and TI MSP430 microcontrollers. The Risc-V and ARM architectures are ascending. Turnkey actions for IoT workloads are possible as well. The command language is close to the Forth 2012 standard.

Microsek is an INTECS OpenSource Hard Real-Time and Networked Operating System compliant to the Osek/Vdx standard and suitable for the development of Embedded Real-Time Applications.

MinopsOS is a tiny operating system for PC computers. It's small enough to fit inside the boot sector of a floppy disk.

Akalon is a Bare-Bones Embedded RTOS that's designed to be simple and portable to any Microprocessor or System (Board). Currently supports the Intel and ARM Architectures.

Since the summer of 2010, the FSAE team High Speed Karlsruhe uses Infineon's XC878 to power its electronics. The XC878 is an 8052 compatible 8-bit µC. Our dedication is to 8-bit real time applications, guaranteed by the powerful peripherals of the XC878. This project aims to publish those portions of our code, which may be of use to a wider audience.

Pharos is a free open-source RTOS for secure, safe and real-time systems with the following characteristics: - Memory and enhanced time partitioning (TSP) - Native support for sporadic, periodic and aperiodic threads - Fixed-priority preemptive scheduler - Execution time protection (threads are prevented from executing for more time than they are configured to) - Small size (full image has ~100 to 300KiB text, ~30KiB data) - Hard real-time determinism - Fast critical sections - Prioritized nested interrupts - inter-partition communication with filters to protect unwanted access - Multicore support (RMP) - Supports ARM9, Cortex-A/R/M and Aarch64, RISC-V64 (64 bits) - The complete TestSuite (see below information) is run successfully for each platform in each release - Tested: more than 170 KLOC of requirement-based tests, executed for each board at each release - Up-to-date User Manual also available See our wiki page for more information.

scmRTOS is tiny Real-Time Preemptive Operating System intended for use with Single-Chip Microcontrollers. scmRTOS is capable to run on small uCs with as little amount of RAM as 512 bytes. The RTOS is written on C++ and supports various platforms.
