Hy, i have a question about the timers in QNX: How are they distributed by the operating system to the processes? If i
use a timer in a program with the timer_Create function then that timer will atach to the system clock (meaning that it
compares the value of the duration of the timer,with a system clock value set by ClockPeriod) or that timer will use
the real time timer from the board(witch I have) with a dedicated interrupt for it. I am asking this because if run my
program (attached) in background from serial terminal, and run the pidin irq it does not say that i have a real time
intrerupt attached to the process, and i don`t know if this is a problem for real time or not. Is there a way to attach
a individual timer intrerupt for a program like the io-pkt-v4 driver or serdebug driver?
I don`t know if it will make my program better or not, but it`s good to ask. I am working on a ARM9 development board
running at 180 MHZ, and my program has jitter and is not real time
