Re: How to make timed sequences in java?
 

Yes, I take the time at the top of the loop and at the end of the loop sleep for the remainder of the 20ms. (Or print a 'broke realtime' message). That's the big downside of an OS, you have to share :(

Yes :-)

On a related note: When designing realtime frameworks and application code for bare metal embedded microcontrollers, it's helpful to increment an element in an array of error counters for realtime margin and other operating assumptions. Monitoring those error counters during development, qualification, stress, and acceptance testing is a great way to increase confidence level that the system is operating as expected.
