- Driver: 8255
- Description: generic 8255 support
- Devices: [standard] 8255 (8255)
- Author: ds
- Status: works
- Updated: Fri, 7 Jun 2002 12:56:45 -0700
-
- The classic in digital I/O. The 8255 appears in Comedi as a single
- digital I/O subdevice with 24 channels. The channel 0 corresponds
- to the 8255's port A, bit 0; channel 23 corresponds to port C, bit
- 7. Direction configuration is done in blocks, with channels 0-7,
- 8-15, 16-19, and 20-23 making up the 4 blocks. The only 8255 mode
- supported is mode 0.
-
- You should enable compilation this driver if you plan to use a board
- that has an 8255 chip. For multifunction boards, the main driver will
- configure the 8255 subdevice automatically.
-
- This driver also works independently with ISA and PCI cards that
- directly map the 8255 registers to I/O ports, including cards with
- multiple 8255 chips. To configure the driver for such a card, the
- option list should be a list of the I/O port bases for each of the
- 8255 chips. For example,
-
- comedi_config /dev/comedi0 8255 0x200,0x204,0x208,0x20c
-
- Note that most PCI 8255 boards do NOT work with this driver, and
- need a separate driver as a wrapper. For those that do work, the
- I/O port base address can be found in the output of 'lspci -v'.
-
- This file contains an exported subdevice for driving an 8255.
-
- To use this subdevice as part of another driver, you need to
- set up the subdevice in the attach function of the driver by
- calling:
-
- subdev_8255_init(device, subdevice, io_function, iobase)
-
- device and subdevice are pointers to the device and subdevice
- structures. io_function will be called to provide the
- low-level input/output to the device, i.e., actual register
- access. io_function will be called with the value of iobase
- as the last parameter. If the 8255 device is mapped as 4
- consecutive I/O ports, you can use NULL for io_function
- and the I/O port base for iobase, and an internal function will
- handle the register access.
-
- In addition, if the main driver handles interrupts, you can
- enable commands on the subdevice by calling subdev_8255_init_irq()
- instead. Then, when you get an interrupt that is likely to be
- from the 8255, you should call subdev_8255_interrupt(), which
- will copy the latched value to a Comedi buffer.

- PCI-9118HR (pci9118hr)
- Status: works
-
- This driver supports AI, AO, DI and DO subdevices.
- AI subdevice supports cmd and insn interface,
- other subdevices support only insn interface.
- For AI:
- - If cmd->scan_begin_src=TRIG_EXT then trigger input is TGIN (pin 46).
- - If cmd->convert_src=TRIG_EXT then trigger input is EXTTRG (pin 44).
- - If cmd->start_src/stop_src=TRIG_EXT then trigger input is TGIN (pin 46).
- - It is not necessary to have cmd.scan_end_arg=cmd.chanlist_len but
- cmd.scan_end_arg modulo cmd.chanlist_len must by 0.
- - If return value of cmdtest is 5 then you've bad channel list
- (it isn't possible mixture S.E. and DIFF inputs or bipolar and unipolar
- ranges).
-
- There are some hardware limitations:
- a) You cann't use mixture of unipolar/bipoar ranges or differencial/single
- ended inputs.
- b) DMA transfers must have the length aligned to two samples (32 bit),
- so there is some problems if cmd->chanlist_len is odd. This driver
- tries bypass this with adding one sample to the end of the every scan
- and discard it on output but this cann't be used if
- cmd->scan_begin_src=TRIG_FOLLOW and is used flag TRIG_WAKE_EOS, then
- driver switch to interrupt driven mode with interrupt after every
- sample.
- c) If isn't used DMA then you can use only mode where
- cmd->scan_begin_src=TRIG_FOLLOW.
-
- Configuration options:
- [0] - PCI bus of device (optional)
- [1] - PCI slot of device (optional)
- If bus/slot is not specified, then first available PCI
- card will be used.
- [2] - 0= standard 8 DIFF/16 SE channels configuration
- n = external multiplexer connected, 1 <= n <= 256
- [3] - 0=autoselect DMA or EOC interrupts operation
- 1 = disable DMA mode

- S&H logic
- 0 != use ADCHN7(pin 23) signal is generated from driver, number

- the hold (in this case external multiplexor can serve only
- 128 channels)
