Dear All, My SimpleRTOS is now hosted on Sourceforge: It implements real preemptive multi-tasking for micro-controllers with a very small memory footprint. It has ports for PIC18, PIC24/dsPIC, PIC32 and Atmel SAM3 (ARM Cortex-M3) devices. The SAM3 and PIC32 ports are being used in some of my current projects and seem to be very stable. The PIC18 port is still buggy. One distinctive feature is the FlexiQueue, which is an inter-process communication queue that can hold objects of different sizes.
