Hi all We are having problems to acquire from 5 pxi 6070. Each card has been configured with 12 channels at 100KS/s. The acquistions stops after few time. We have big comedi buffers. Using a logic analyzer we have seing pci bus cycles and during acquisition time, no burst transfers are used to send data from acquisition cards to comedi buffers. PCI has its best performance in burst transfers and we would like to know if comedi use one addres phase and one data phase for each sample due to any reason or if it is posible to configure comedi to use burst transfers. We have tried to change master latency timer in pxi 6070 cards but no burst transfers are obtained. ¿Anybody can tell us something about that? Thank you very much Best regards -- Daniel Machón [damachon_at_eresmas.net] --
