Utilization of simple real-time operating system on 8-bit microcontroller

Abstract

The paper deals with small real-time operating system developed at our institute together with an application which uses this system and thus provides verification of this system in a portable data acquisition unit. The system, named RTMON is used mainly as a teaching aid for lessons of microcontroller programming. It makes it possible for students to write applications in C language with several concurrently running processes in a simple way. However, it can be used also in practical applications, which is demonstrated by the data acquisition unit described in this paper. The system is implemented for 8-bit microcontrollers with the HC(S)08 core made by Freescale and for Atmel AVR Mega8 microcontrollers.
