Where can I get register-level programming information for the PCI-6602 board ?

[Tiago de Paula]

I need to use an PCI-6602 timer/counter board as part of a data aquisition system, using the GNU/Linux operating system.

The comedi drivers don't provide suport the PCI-6602 board, so I am forced to write my own driver.

The user manual for the PCI-6602 board says that the NI-TIO chipset is backwards compatible with the DAQ-STC chipset used in the E series multifuncion boards. But I need to use the board's special features, such as DMA and 32 bit counters. For that, I would need specific register-level information for the NI-TIO chipset.

I was disappointed not to find absolutely anything regarding register-level programming for that board on the National Instrumen
ts website. I bought the hardware with the idea that this type of information would be avaiable.

Is it possible at all to obtain that information ?

Unfortunately, National Instruments does provide register-level programming information on boards using the proprietary NI-TIO counter chip at this time. This includes all 660x boards.
