The channels are configurable as * input or output in 2 groups (0 to 7, 8 to 15). Configuring any * channel implicitly configures all channels in the same group. * * TODO: * 1. Add the two milliamp ranges to the AO subdevice (0 to 20 mA, * 4 to 20 mA). * 2. Read the initial ranges and values of the AO subdevice at * start-up instead of reinitializing them. * 3. Implement calibration. */ #include <linux/module.h> #include <linux/comedi/comedi_pci.h> /* * PCI Bar 2 I/O Register map (dev->iobase) */ #define PCI1723_AO_REG(x) … #define PCI1723_BOARD_ID_REG … #define PCI1723_BOARD_ID_MASK … #define PCI1723_SYNC_CTRL_REG … #define PCI1723_SYNC_CTRL(x) … #define PCI1723_SYNC_CTRL_ASYNC … #define PCI1723_SYNC_CTRL_SYNC … #define PCI1723_CTRL_REG … #define PCI1723_CTRL_BUSY … #define PCI1723_CTRL_INIT … #define PCI1723_CTRL_SELF … #define PCI1723_CTRL_IDX(x) … #define PCI1723_CTRL_RANGE(x) … #define PCI1723_CTRL_SEL(x) … #define PCI1723_CTRL_GAIN … #define PCI1723_CTRL_OFFSET … #define PCI1723_CTRL_CHAN(x) … #define PCI1723_CALIB_CTRL_REG … #define PCI1723_CALIB_CTRL_CS … #define PCI1723_CALIB_CTRL_DAT … #define PCI1723_CALIB_CTRL_CLK … #define PCI1723_CALIB_STROBE_REG … #define PCI1723_DIO_CTRL_REG … #define PCI1723_DIO_CTRL_HDIO … #define PCI1723_DIO_CTRL_LDIO … #define PCI1723_DIO_DATA_REG … #define PCI1723_CALIB_DATA_REG … #define PCI1723_SYNC_STROBE_REG … #define PCI1723_RESET_AO_STROBE_REG … #define PCI1723_RESET_CALIB_STROBE_REG … #define PCI1723_RANGE_STROBE_REG … #define PCI1723_VREF_REG … #define PCI1723_VREF(x) … #define PCI1723_VREF_NEG10V … #define PCI1723_VREF_0V … #define PCI1723_VREF_POS10V … static int pci1723_ao_insn_write(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static int pci1723_dio_insn_config(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static int pci1723_dio_insn_bits(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static int pci1723_auto_attach(struct comedi_device *dev, unsigned long context_unused) { … } static struct comedi_driver adv_pci1723_driver = …; static int adv_pci1723_pci_probe(struct pci_dev *dev, const struct pci_device_id *id) { … } static const struct pci_device_id adv_pci1723_pci_table[] = …; MODULE_DEVICE_TABLE(pci, adv_pci1723_pci_table); static struct pci_driver adv_pci1723_pci_driver = …; module_comedi_pci_driver(…); MODULE_AUTHOR(…) …; MODULE_DESCRIPTION(…) …; MODULE_LICENSE(…) …;
