It is designed to host +control loops. So called functions should be short. + +Every job must specify deadline and if not set otherwise also its duration. + +If tasks support is enabled jobs can be also executed on multiple tasks, which is +handy if you divide sensor reading and control algorithm, because control +algorithm can than run when for example mcu waiting for response from sensor. +Always be sure that jobs are running on tasks with highest priority, otherwise +deadlines might not be fulfilled every time. + +Be aware of taking mutexes and semaphores. It can sometime result in long task +suspension and that would result to deadline misses. -- cgit v1.2.3
