Hi there!
I would like to have a pulse of 200 microseconds in
QNX 6.1. Is it possible? Using pulse/MsgReceive, I
got 1 millisecond, but below that, it isn’t correct.
I have re-scheduled to get max priority and using
FIFO.

No this is not possible in 6.1 (due to timer resolution), however, it is
supposed to be possible in 6.2.

I’d tried in 6.2 and it continues not possible.

Have you changed tick size resolution with ClockPeriod()?

Yes, I have adjusted to 30 microseconds (the min is 10 micros), but I
continue getting it around >900micros and <1milli… no precision.
Should I to use an external interrupt trigger??? Or use a PIC to do
that?? Suggestions?
