Despite no detailed log is maintained, it can * be said that the driver is quite tested and stable. * * The boards may be autocalibrated using the comedi_calibrate * utility. * * Configuration options: not applicable, uses PCI auto config * * For commands, the scanned channels must be consecutive * (i.e. 4-5-6-7, 2-3-4,...), and must all have the same * range and aref. * * AI Triggering: * For start_src == TRIG_EXT, the A/D EXTERNAL TRIGGER IN (pin 45) is used. * For 1602 series, the start_arg is interpreted as follows: * start_arg == 0 => gated trigger (level high) * start_arg == CR_INVERT => gated trigger (level low) * start_arg == CR_EDGE => Rising edge * start_arg == CR_EDGE | CR_INVERT => Falling edge * For the other boards the trigger will be done on rising edge */ /* * TODO: * analog triggering on 1602 series */ #include <linux/module.h> #include <linux/delay.h> #include <linux/interrupt.h> #include <linux/comedi/comedi_pci.h> #include <linux/comedi/comedi_8255.h> #include <linux/comedi/comedi_8254.h> #include "amcc_s5933.h" #define AI_BUFFER_SIZE … #define AO_BUFFER_SIZE … /* * PCI BAR1 Register map (devpriv->pcibar1) */ #define PCIDAS_CTRL_REG … #define PCIDAS_CTRL_INT(x) … #define PCIDAS_CTRL_INT_NONE … #define PCIDAS_CTRL_INT_EOS … #define PCIDAS_CTRL_INT_FHF … #define PCIDAS_CTRL_INT_FNE … #define PCIDAS_CTRL_INT_MASK … #define PCIDAS_CTRL_INTE … #define PCIDAS_CTRL_DAHFIE … #define PCIDAS_CTRL_EOAIE … #define PCIDAS_CTRL_DAHFI … #define PCIDAS_CTRL_EOAI … #define PCIDAS_CTRL_INT_CLR … #define PCIDAS_CTRL_EOBI … #define PCIDAS_CTRL_ADHFI … #define PCIDAS_CTRL_ADNEI … #define PCIDAS_CTRL_ADNE … #define PCIDAS_CTRL_DAEMIE … #define PCIDAS_CTRL_LADFUL … #define PCIDAS_CTRL_DAEMI … #define PCIDAS_CTRL_AI_INT … #define PCIDAS_CTRL_AO_INT … #define PCIDAS_AI_REG … #define PCIDAS_AI_FIRST(x) … #define PCIDAS_AI_LAST(x) … #define PCIDAS_AI_CHAN(x) … #define PCIDAS_AI_GAIN(x) … #define PCIDAS_AI_SE … #define PCIDAS_AI_UNIP … #define PCIDAS_AI_PACER(x) … #define PCIDAS_AI_PACER_SW … #define PCIDAS_AI_PACER_INT … #define PCIDAS_AI_PACER_EXTN … #define PCIDAS_AI_PACER_EXTP … #define PCIDAS_AI_PACER_MASK … #define PCIDAS_AI_EOC … #define PCIDAS_TRIG_REG … #define PCIDAS_TRIG_SEL(x) … #define PCIDAS_TRIG_SEL_NONE … #define PCIDAS_TRIG_SEL_SW … #define PCIDAS_TRIG_SEL_EXT … #define PCIDAS_TRIG_SEL_ANALOG … #define PCIDAS_TRIG_SEL_MASK … #define PCIDAS_TRIG_POL … #define PCIDAS_TRIG_MODE … #define PCIDAS_TRIG_EN … #define PCIDAS_TRIG_BURSTE … #define PCIDAS_TRIG_CLR … #define PCIDAS_CALIB_REG … #define PCIDAS_CALIB_8800_SEL … #define PCIDAS_CALIB_TRIM_SEL … #define PCIDAS_CALIB_DAC08_SEL … #define PCIDAS_CALIB_SRC(x) … #define PCIDAS_CALIB_EN … #define PCIDAS_CALIB_DATA … #define PCIDAS_AO_REG … #define PCIDAS_AO_EMPTY … #define PCIDAS_AO_DACEN … #define PCIDAS_AO_START … #define PCIDAS_AO_PACER(x) … #define PCIDAS_AO_PACER_SW … #define PCIDAS_AO_PACER_INT … #define PCIDAS_AO_PACER_EXTN … #define PCIDAS_AO_PACER_EXTP … #define PCIDAS_AO_PACER_MASK … #define PCIDAS_AO_CHAN_EN(c) … #define PCIDAS_AO_CHAN_MASK … #define PCIDAS_AO_UPDATE_BOTH … #define PCIDAS_AO_RANGE(c, r) … #define PCIDAS_AO_RANGE_MASK(c) … /* * PCI BAR2 Register map (devpriv->pcibar2) */ #define PCIDAS_AI_DATA_REG … #define PCIDAS_AI_FIFO_CLR_REG … /* * PCI BAR3 Register map (dev->iobase) */ #define PCIDAS_AI_8254_BASE … #define PCIDAS_8255_BASE … #define PCIDAS_AO_8254_BASE … /* * PCI BAR4 Register map (devpriv->pcibar4) */ #define PCIDAS_AO_DATA_REG(x) … #define PCIDAS_AO_FIFO_REG … #define PCIDAS_AO_FIFO_CLR_REG … /* analog input ranges for most boards */ static const struct comedi_lrange cb_pcidas_ranges = …;
