RTMON2 - new version of educational operating system

Abstract

This article describes improved version of simple educational operating system RTMON, which we developed. This system, named RTMON2, should be used mainly as teaching aid in microcontroller programming lessons, but it can be useful also for other projects such as student's theses. The system offers an easy way to develop applications for 8-bit microcontrollers with several concurrently running tasks. The new version of the system was developed using our experience from teaching lessons with the previous version. RTMON2 improves usability in real-world applications by more efficient usage of RAM memory. The system currently runs on GB60, QE128 and QG4 derivatives of the Freescale HCS08 microcontroller family and also on Atmel AVR ATMega8 microcontroller.
