For the older Lab-PC+, not all input * ranges and analog references will work, the available ranges/arefs * will depend on how you have configured the jumpers on your board * (see your owner's manual). * * Kernel-level ISA plug-and-play support for the lab-pc-1200 boards * has not yet been added to the driver, mainly due to the fact that * I don't know the device id numbers. If you have one of these boards, * please file a bug report at https://comedi.org/ so I can get the * necessary information from you. * * The 1200 series boards have onboard calibration dacs for correcting * analog input/output offsets and gains. The proper settings for these * caldacs are stored on the board's eeprom. To read the caldac values * from the eeprom and store them into a file that can be then be used * by comedilib, use the comedi_calibrate program. * * The Lab-pc+ has quirky chanlist requirements when scanning multiple * channels. Multiple channel scan sequence must start at highest channel, * then decrement down to channel 0. The rest of the cards can scan down * like lab-pc+ or scan up from channel zero. Chanlists consisting of all * one channel are also legal, and allow you to pace conversions in bursts. * * NI manuals: * 341309a (labpc-1200 register manual) * 320502b (lab-pc+) */ #include <linux/module.h> #include <linux/comedi/comedidev.h> #include "ni_labpc.h" #include "ni_labpc_isadma.h" static const struct labpc_boardinfo labpc_boards[] = …; static int labpc_attach(struct comedi_device *dev, struct comedi_devconfig *it) { … } static void labpc_detach(struct comedi_device *dev) { … } static struct comedi_driver labpc_driver = …; module_comedi_driver(…); MODULE_AUTHOR(…) …; MODULE_DESCRIPTION(…) …; MODULE_LICENSE(…) …;
