Well the thing is that at the same time I have to acquire data from a USB device with a rate of 129 packets/second and the device doesn't have an internal buffer. So if because of some OS jitter, I miss a packet from the USB, or because of some jitter the flickering pattern is delayed, my experiment will be invalid. I have two separate Python programs for these tasks. If I run them concurrently, RaspPi can miss some packets or miss flickering rate but BBB seems to perform much better but I don't want to take risks as I'll also want to do some signal processing in the acquisition loop, etc. -- Ozan Çağlayan Research Assistant Galatasaray University - Computer Engineering Dept. http://www.ozancaglayan.com -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
