Objet : Re: RE: Uncertainty about timer under the QNX RTOS

1.Yes, it is. I have tried many times, results are similar.

2.I use signal, not pulse, and the priority of the thread waiting for such signal is

200.

3.I have no idea how to write an ISR for the HPET while it has a default one

comes from the kernel maybe.

4.what I want to acquire is a periodic timing(250us) with high stability, so I could

get high synchronization  performence of motion control.

Thanks again!
