Implementation and application of a simple real-time OS for 8-bit microcontrollers

Abstract

This paper presents small real-time operating system which has been developed at our institute and also an application and practical verification of this system in a portable data acquisition unit. The system, named RTMON is intended mainly as a teaching aid for lessons of microcontroller programming where it allows the students to simply write applications in C language with several concurrently running processes. However, it can also be used in practical applications, as is demonstrated by the data acquisition unit described in this paper. The system works on 8-bit microcontrollers with the HC(S)08 core made by Freescale and also on Atmel AVR Mega8 microcontrollers.
