I may be late to this party, but was wondering if uCOS is still free? Read about it on the rabbit pages, and also was reading about it being open, but after going to the 'main site' to get more details before i go out and buy the book, it only looks commercial now.
If it is now a commercial product, any one have recommendations for a really small free RTkernel that would mate well to a z80 and rabbit2000? ( perhaps even a 8051, but i know thats a stretch due to the radically different architecture ).
The 'target' will be doing simple monitoring of sensors and changing of remote parameters from a serial port based human interface ( i.e., palm pilot ) so i dont need anything fancy, but didn't want to 'do it myself'.
