This is my first post. Hope I can learn and discuss hot topics As Many Aa Possible.
My server pgm’s structure is: The main thread periodically run a sub thread(server_manager) to do certin work. The stimulation frequency is 40Hz, that is running the subthread /25ms.Although I can realize it using the normal timer fucntions, since the sub thread is also in charge of sending a message to the client process by using a budget timer(15ms after its running), I tend to use the IRQ8 RTC and ISR to realize strict periodic stimulation of the sub thread. My questions are:
1.After reading the post “high-frequency timebase”, some parts are not clear:
1)is the IRQ8 handler complete?
2).the setup and restore part should be put where? the main(), right?
3).how to set the IRQ8’s interrupt frequency to 40hz.
4).where should I declare the timerevent? Is the declaring method the same as one used in normal timer-create/settime functions?
2.according to my requirements on frequency, which type should I prefer, interruptattach() or interruptattachevent()? whats their main differences?
If ok, could some experts give me a complete pgm example which is using the IRQ8 RTC to run a thread periodically? or give me a general structure according to discription on my server pgm?
Are there some classic articles on this topic? I have seen Mr Roben Krten’s book and QNX development support, but there is no. Actually I even could not find a complete example on how to use IRQ8 (and even IRQ).
Since I am only a newuser, too many things need you experts help!!
(Mr steinhoff, I have seen your post and get great help, if ok, could you send me a complete such example?)
Thanks for all very much !!
