I'm attempting to understanding how to use the libpruio code base. *Goal*: Read 2 adc values as fast as possible. *Understanding*: libpruio has a shared buffer that the pru writes to in this case from the adc, which will be then consumed by the userland application.
Going over io_input.c there a few things I still don't understand. pruio_config(io, 1, 0x1FE, 0, 4) Could someone expand on these two parameters--I've read the docs just not sure I understand them: *Samp number of samples to fetch (defaults to zero)* * Tmr timer value in [ns] to specify the sampling rate (defaults to zero, MM only)* So.. assuming I want the fastest possible pru sampling dumped into the shared buffer that is then consumed by the shared buffer what could my config call be? Also the sleep timing call-- are there specific times that need to be waited for specific buffer sizes-- or is that a guess and check sorta thing. forgive me if these are stupid questions- just trying to wrap my head around this issue. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
