17 * Description: ADDI-DATA APCI-1564 Digital I/O board
18 * Devices: [ADDI-DATA] APCI-1564 (addi_apci_1564)
19 * Author: H Hartley Sweeten <hsweeten@visionengravers.com>
20 * Updated: Thu, 02 Jun 2016 13:12:46 -0700
23 * Configuration Options: not applicable, uses comedi PCI auto config
25 * This board has the following features:
26 * - 32 optically isolated digital inputs (24V), 16 of which can
27 * generate change-of-state (COS) interrupts (channels 4 to 19)
28 * - 32 optically isolated digital outputs (10V to 36V)
29 * - 1 8-bit watchdog for resetting the outputs
32 * - 2 diagnostic inputs
34 * The COS, timer, and counter subdevices all use the dev->read_subdev to
35 * return the interrupt status. The sample data is updated and returned when
36 * any of these subdevices generate an interrupt. The sample data format is:
39 * ----- ------------------------------------------
42 * 29 counter 2 interrupt
43 * 28 counter 1 interrupt
44 * 27 counter 0 interrupt
46 * 19:4 COS digital input state (channels 19 to 4)
49 * The COS interrupts must be configured using an INSN_CONFIG_DIGITAL_TRIG
50 * instruction before they can be enabled by an async command. The COS
51 * interrupts will stay active until canceled.
53 * The timer subdevice does not use an async command. All control is handled
54 * by the (*insn_config).
56 * FIXME: The format of the ADDI_TCW_TIMEBASE_REG is not descibed in the
57 * datasheet I have. The INSN_CONFIG_SET_CLOCK_SRC currently just writes
58 * the raw data[1] to this register along with the raw data[2] value to the
59 * ADDI_TCW_RELOAD_REG. If anyone tests this and can determine the actual
60 * timebase/reload operation please let me know.
62 * The counter subdevice also does not use an async command. All control is
63 * handled by the (*insn_config).
65 * FIXME: The operation of the counters is not really described in the
66 * datasheet I have. The (*insn_config) needs more work.
