Goodafternoon all, I've seen some different OS ports for PIC18. But not sure which one is more effecitve and less painfull to design. SalvoRTOS, PIC18OS, FreeRTOS, uC/OS-II for PIC18.. Whats your comments on that? Thanks, G=F6khan SEVER. -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
