See the notes for 43the ni_atmio.o driver for additional information about these boards. 44 45Autocalibration is supported on many of the devices, using the 46comedi_calibrate (or comedi_soft_calibrate for m-series) utility. 47M-Series boards do analog input and analog output calibration entirely 48in software. The software calibration corrects 49the analog input for offset, gain and 50nonlinearity. The analog outputs are corrected for offset and gain. 51See the comedilib documentation on comedi_get_softcal_converter() for 52more information. 53 54By default, the driver uses DMA to transfer analog input data to 55memory. When DMA is enabled, not all triggering features are 56supported. 57 58Digital I/O may not work on 673x. 59 60Note that the PCI-6143 is a simultaineous sampling device with 8 convertors. 61With this board all of the convertors perform one simultaineous sample during 62a scan interval. The period for a scan is used for the convert time in a 63Comedi cmd. The convert trigger source is normally set to TRIG_NOW by default. 64 65The RTSI trigger bus is supported on these cards on 66subdevice 10. See the comedilib documentation for details. 67 68Information (number of channels, bits, etc.) for some devices may be 69incorrect. Please check this and submit a bug if there are problems 70for your device. 71 72SCXI is probably broken for m-series boards. 73 74Bugs: 75 - When DMA is enabled, COMEDI_EV_CONVERT does 76 not work correctly. 77 78*/ 79/* 80 The PCI-MIO E series driver was originally written by 81 Tomasz Motylewski <...>, and ported to comedi by ds. 82 83 References: 84 85 341079b.pdf PCI E Series Register-Level Programmer Manual 86 340934b.pdf DAQ-STC reference manual 87 88 322080b.pdf 6711/6713/6715 User Manual 89 90 320945c.pdf PCI E Series User Manual 91 322138a.pdf PCI-6052E and DAQPad-6052E User Manual 92 93 ISSUES: 94 95 need to deal with external reference for DAC, and other DAC 96 properties in board properties 97 98 deal with at-mio-16de-10 revision D to N changes, etc. 99 100 need to add other CALDAC type 101 102 need to slow down DAC loading. I don't trust NI's claim that 103 two writes to the PCI bus slows IO enough. I would prefer to 104 use udelay().
