B4J Question B4J with linux real time patch

Hi

Do you have run b4j(java) app in real-time patch of linux ? I need to get a stable timer 1ms or 500us !

real-time patch = http://www.pengutronix.de/software/linux-rt/debian_en.html

I don't think that it will make any difference. For 1ms interval you can use a loop instead of a timer.

Hi

when i use loop, Do i need use sleep() to share time with kernel ?

If it is a non-ui app and you don't need to handle any asynchronous event then you don't need to "sleep".
If you do need to handle events then you can use CallSubDelayed to call the loop method from time to time and allow the events to be raised.
