I am writing a register level driver (using VenturCom's RTX) for a PCI-6035E, and I've seen the NI docs, but I still need information on programming a digital input to cause an interrupt that an ISR in my driver can catch, and how to bypass the FIFO and perform an instantaneous (one-shot) read of an analog input. Also, does anyone know of a source for register level programming information/examples for the PCI-6035E.
