If your board is not - * recognized, please send the output of 'cat /proc/isapnp' (you may need to - * modprobe the isa-pnp module for /proc/isapnp to exist) so the id numbers - * for your board can be added to the driver. - * - * Otherwise, you can use the isapnptools package to configure your board. - * Use isapnp to configure the I/O base and IRQ for the board, and then pass - * the same values as parameters in comedi_config. A sample isapnp.conf file - * is included in the etc/ directory of Comedilib. - * - * Comedilib includes a utility to autocalibrate these boards. The boards - * seem to boot into a state where the all calibration DACs are at one - * extreme of their range, thus the default calibration is terrible. - * Calibration at boot is strongly encouraged. - * - * To use the extended digital I/O on some of the boards, enable the - * 8255 driver when configuring the Comedi source tree. - * - * External triggering is supported for some events. The channel index - * (scan_begin_arg, etc.) maps to PFI0 - PFI9. - * - * Some of the more esoteric triggering possibilities of these boards are - * not supported. - */ - -/* - * The real guts of the driver is in ni_mio_common.c, which is included - * both here and in ni_pcimio.c - * - * Interrupt support added by Truxton Fulton <trux@truxton.com> - * - * References for specifications: - * 340747b.pdf Register Level Programmer Manual (obsolete) - * 340747c.pdf Register Level Programmer Manual (new) - * DAQ-STC reference manual - * - * Other possibly relevant info: - * 320517c.pdf User manual (obsolete) - * 320517f.pdf User manual (new) - * 320889a.pdf delete - * 320906c.pdf maximum signal ratings - * 321066a.pdf about 16x - * 321791a.pdf discontinuation of at-mio-16e-10 rev. c - * 321808a.pdf about at-mio-16e-10 rev P - * 321837a.pdf discontinuation of at-mio-16de-10 rev d - * 321838a.pdf about at-mio-16de-10 rev N - * - * ISSUES: - * - need to deal with external reference for DAC, and other DAC - * properties in board properties - * - deal with at-mio-16de-10 revision D to N changes, etc. - */ - -#include <linux/module.h> -#include <linux/interrupt.h> -#include "../comedidev.h" - -#include <linux/isapnp.h> - -#include "ni_stc.h" -#include "8255.h" - -/* AT specific setup */ -static const struct ni_board_struct ni_boards[] = { - { - .name = "at-mio-16e-1", - .device_id = 44, - .isapnp_id = 0x0000, /* XXX unknown */ - .n_adchan = 16, - .ai_maxdata = 0x0fff, - .ai_fifo_depth = 8192, - .gainlkup = ai_gain_16, - .ai_speed = 800, - .n_aochan = 2, - .ao_maxdata = 0x0fff, - .ao_fifo_depth = 2048, - .ao_range_table = &range_ni_E_ao_ext, - .ao_speed = 1000, - .caldac = { mb88341 }, - }, { - .name = "at-mio-16e-2", - .device_id = 25, - .isapnp_id = 0x1900, - .n_adchan = 16, - .ai_maxdata = 0x0fff, - .ai_fifo_depth = 2048, - .gainlkup = ai_gain_16, - .ai_speed = 2000, - .n_aochan = 2, - .ao_maxdata = 0x0fff, - .ao_fifo_depth = 2048, - .ao_range_table = &range_ni_E_ao_ext, - .ao_speed = 1000, - .caldac = { mb88341 }, - }, { - .name = "at-mio-16e-10", - .device_id = 36, - .isapnp_id = 0x2400, - .n_adchan = 16, - .ai_maxdata = 0x0fff, - .ai_fifo_depth = 512, - .gainlkup = ai_gain_16, - .ai_speed = 10000, - .n_aochan = 2, - .ao_maxdata = 0x0fff, - .ao_range_table = &range_ni_E_ao_ext, - .ao_speed = 10000, - .caldac = { ad8804_debug }, - }, { - .name = "at-mio-16de-10", - .device_id = 37, - .isapnp_id = 0x2500, - .n_adchan = 16, - .ai_maxdata = 0x0fff, - .ai_fifo_depth = 512, - .gainlkup = ai_gain_16, - .ai_speed = 10000, - .n_aochan = 2, - .ao_maxdata = 0x0fff, - .ao_range_table = &range_ni_E_ao_ext, - .ao_speed = 10000, - .caldac = { ad8804_debug }, - .has_8255 = 1, - }, { - .name = "at-mio-64e-3", - .device_id = 38, - .isapnp_id = 0x2600, - .n_adchan = 64, - .ai_maxdata = 0x0fff, - .ai_fifo_depth = 2048, - .gainlkup = ai_gain_16, - .ai_speed = 2000, - .n_aochan = 2, - .ao_maxdata = 0x0fff, - .ao_fifo_depth = 2048, - .ao_range_table = &range_ni_E_ao_ext, - .ao_speed = 1000, - .caldac = { ad8804_debug }, - }, { - .name = "at-mio-16xe-50", - .device_id = 39, - .isapnp_id = 0x2700, - .n_adchan = 16, - .ai_maxdata = 0xffff, - .ai_fifo_depth = 512, - .alwaysdither = 1, - .gainlkup = ai_gain_8, - .ai_speed = 50000, - .n_aochan = 2, - .ao_maxdata = 0x0fff, - .ao_range_table = &range_bipolar10, - .ao_speed = 50000, - .caldac = { dac8800, dac8043 }, - }, { - .name = "at-mio-16xe-10", - .device_id = 50, - .isapnp_id = 0x0000, /* XXX unknown */ - .n_adchan = 16, - .ai_maxdata = 0xffff, - .ai_fifo_depth = 512, - .alwaysdither = 1, - .gainlkup = ai_gain_14, - .ai_speed = 10000, - .n_aochan = 2, - .ao_maxdata = 0xffff, - .ao_fifo_depth = 2048, - .ao_range_table = &range_ni_E_ao_ext, - .ao_speed = 1000, - .caldac = { dac8800, dac8043, ad8522 }, - }, { - .name = "at-ai-16xe-10", - .device_id = 51, - .isapnp_id = 0x0000, /* XXX unknown */ - .n_adchan = 16, - .ai_maxdata = 0xffff, - .ai_fifo_depth = 512, - .alwaysdither = 1, /* unknown */ - .gainlkup = ai_gain_14, - .ai_speed = 10000, - .caldac = { dac8800, dac8043, ad8522 }, - }, -};
