RTOS Debugging: When the important stuff has to wait

Priority inversion at work – the high-priority (red) task is blocked by lower priority tasks. The central idea underlying an RTOS with a fixed-priority scheduler is that a high-priority task should be scheduled ahead of one with lower priority. If necessary, the RTOS can even pre-empt the running task, forcing it to yield the CPU to [...]

RTOS debugging: Dealing with timing issues

There is no doubt a learning curve when you begin using a real-time operating system (RTOS) in your development. You will work at a higher abstraction level, using more or less parallel tasks rather than just subroutines, and you will need to consider how your tasks shall share data and the processor time with each [...]
