Description: National Instruments PCI-MIO-E series and M series (all boards)<p>
Author: ds, John Hallen, Frank Mori Hess, Rolf Mueller, Herbert Peremans, Herman Bruyninckx, Terry Barnaby Status: works Devices: [National Instruments] PCI-MIO-16XE-50 (ni_pcimio), PCI-MIO-16XE-10, PXI-6030E, PCI-MIO-16E-1, PCI-MIO-16E-4, PCI-6014, PCI-6040E,PXI-6040E, PCI-6030E, PCI-6031E, PCI-6032E, PCI-6033E, PCI-6071E, PCI-6023E, PCI-6024E, PCI-6025E, PXI-6025E, PCI-6034E, PCI-6035E, PCI-6052E, PCI-6110, PCI-6111, PCI-6220, PCI-6221, PCI-6224, PCI-6225, PCI-6229, PCI-6250, PCI-6251, PCIe-6251, PCI-6254, PCI-6259, PCIe-6259, PCI-6280, PCI-6281, PXI-6281, PCI-6284, PCI-6289, PCI-6711, PXI-6711, PCI-6713, PXI-6713, PXI-6071E, PCI-6070E, PXI-6070E, PXI-6052E, PCI-6036E, PCI-6731, PCI-6733, PXI-6733, PCI-6143, PXI-6143<p>
These boards are almost identical to the AT-MIO E series, except that they use the PCI bus instead of ISA (i.e., AT). See the notes for the ni_atmio.o driver for additional information about these boards.<p>
By default, the driver uses DMA to transfer analog input data to memory. When DMA is enabled, not all triggering features are supported.<p>
Note that the PCI-6143 is a simultaneous sampling device with 8 convertors. With this board all of the convertors perform one simultaneous sample during a scan interval. The period for a scan is used for the convert time in an Analgoy cmd. The convert trigger source is normally set to TRIG_NOW by default.<p>
The RTSI trigger bus is supported on these cards on subdevice 10. See the Analogy library documentation for details.<p>

ISSUES:<ul>
<li>When DMA is enabled, XXX_EV_CONVERT does not work correctly.</li><li>Calibration is not fully implemented</li><li>SCXI is probably broken for m-series boards</li><li>Digital I/O may not work on 673x.</li><li>Information (number of channels, bits, etc.) for some devices may be incorrect. Please check this and submit a bug if there are problems for your device.</li><li>Need to deal with external reference for DAC, and other DAC properties in board properties</li><li>Deal with at-mio-16de-10 revision D to N changes, etc.</li><li>Need to add other CALDAC type</li><li>Need to slow down DAC loading. I don't trust NI's claim that two writes to the PCI bus slows IO enough. I would prefer to use a4l_udelay(). Timing specs: (clock) AD8522 30ns DAC8043 120ns DAC8800 60ns MB88341 ? </li></ul>
