RE: [uCsimm] SPI

How much skew is there in RTLinux periodic timers? Can they be within 62.5us
of the expected time? I know interrupts on RTLinux on the uCSimm take about
130us to be serviced, so using the interrupt method for filling the buffer
won't work.
To do the CBR stream, I am going to try the easy way with the SPI and trying
to service it quick enough. If it doesn't work then I will build some
supporting circuitry :)
