PCI_1602
/dev/ixpcin
The n is the IXPCI device number.
- IXPCI_GET_INFO
- Retrieve a device's information, and put it into the ixpci_devinfo (ixpci_devinfo_t) structure. Example: list.c.
- IXPCI_READ_REG
- Read a specified register's value, and put the value into the ixpci_reg (ixpci_reg_t) structure Example: ixpci1800/dio.c.
- IXPCI_WRITE_REG
- Write a given value to a specified register. Example: ixpci1800/dio.c.
- IXPCI_RESET
- Reset device.
- Stop the timer0/1/2.
- Reset the control register.
- A/D channel 0, Gain control PGA = 1.
- Input range control = PGA (+/- 5V.)
- Reset the MagicScan controller.
- Assert the MagicScan handshake control bit (bit-13.)
- Clear FIFO.
- Clear DO to 0.
- Clear DA1/2 to 0.
Example: ixpci1800/reset.c.
- IXPCI_TIME_SPAN IXPCI_BLOCK IXPCI_DELAY IXPCI_WAIT
- IXPCI_TIME_SPAN uses the 8254 counter-2 to be the machine-indepent-timer by the internal 8 MHz clock. Command will be blocked before the countering has finished. The maximum counter value is 8190 micro-seconds. IXPCI_TIME_SPAN, IXPCI_BLOCK, IXPCI_DELAY, and IXPCI_WAIT all are identical. Example ixpci1602/time_span.c.
- ixpci_devinfo_t
- The data type of structure ixpci_devinfo which contains a device's id, base address, and so on. Example: list.c.
- ixpci_reg_t
- The data type of structure ixpci_reg which contains a register's id and value. Example: pci1602/port.c.

- IXPCI_DA2 R W
- Digital to Analog Channel 2. IXPCI_DA2 is the short term of IXPCI_DA_CHANNEL_2.
