Generally speaking, any problem can be easily avoided if application is designed more carefully. Using intertask communication by calling Operating System functions is the best way to avoid any problem with intertask interference. Also, if you have shared resources (e.g. COM port) you should use some semaphore that tells you if resource is already taken by some of tasks. Careful assignement of priorities to tasks is also good way of avoiding problems. Having cooperative scheduling yields even more carefull application design since even tasks with higher priority will have to wait some low priority task to release CPU. So, it's all about application design. About your cooperative scheduler... is it some standard piece of software or something that you wrote? I'm asking this because I'm working on my own version of embedded ultra-low-footprint (approx. 1.5kB) cooperative OS for LPC MCU's so we might share ideas on this? Thing is that I have this stupid neural network that I'm supposed to run with many other things in parallel and it takes up to 10MIPS for neuro code so I really need to use each micro-second of CPU time. That's where OS fits as perfect solution. Regards, Igor
