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 + + 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 "../comedidev.h" + +#include +#include + +#include "ni_stc.h" +#include "8255.h" + +#undef DEBUG + +#define ATMIO 1 +#undef PCIMIO + +/* + * AT specific setup + */ + +#define NI_SIZE 0x20 + +#define MAX_N_CALDACS 32 + +static const ni_board ni_boards[] = { + {device_id:44, + isapnp_id:0x0000,/* XXX unknown */ + name: "at-mio-16e-1", + n_adchan:16, + adbits: 12, + ai_fifo_depth:8192, + alwaysdither:0, + gainlkup:ai_gain_16, + ai_speed:800, + n_aochan:2, + aobits: 12, + ao_fifo_depth:2048, + .ao_range_table = &range_ni_E_ao_ext, + ao_unipolar:1, + ao_speed:1000, + has_8255:0, + .num_p0_dio_channels = 8, + caldac: {mb88341}, + }, + {device_id:25, + isapnp_id:0x1900, + name: "at-mio-16e-2", + n_adchan:16, + adbits: 12, + ai_fifo_depth:2048, + alwaysdither:0, + gainlkup:ai_gain_16, + ai_speed:2000, + n_aochan:2, + aobits: 12, + ao_fifo_depth:2048, + .ao_range_table = &range_ni_E_ao_ext, + ao_unipolar:1, + ao_speed:1000, + has_8255:0, + .num_p0_dio_channels = 8, + caldac: {mb88341}, + }, + {device_id:36, + isapnp_id:0x2400, + name: "at-mio-16e-10", + n_adchan:16, + adbits: 12, + ai_fifo_depth:512, + alwaysdither:0, + gainlkup:ai_gain_16, + ai_speed:10000, + n_aochan:2, + aobits: 12, + ao_fifo_depth:0, + .ao_range_table = &range_ni_E_ao_ext, + ao_unipolar:1, + ao_speed:10000, + .num_p0_dio_channels = 8, + caldac: {ad8804_debug}, + has_8255:0, + }, + {device_id:37, + isapnp_id:0x2500, + name: "at-mio-16de-10", + n_adchan:16, + adbits: 12, + ai_fifo_depth:512, + alwaysdither:0, + gainlkup:ai_gain_16, + ai_speed:10000, + n_aochan:2, + aobits: 12, + ao_fifo_depth:0, + .ao_range_table = &range_ni_E_ao_ext, + ao_unipolar:1, + ao_speed:10000, + .num_p0_dio_channels = 8, + caldac: {ad8804_debug}, + has_8255:1, + }, + {device_id:38, + isapnp_id:0x2600, + name: "at-mio-64e-3", + n_adchan:64, + adbits: 12, + ai_fifo_depth:2048, + alwaysdither:0, + gainlkup:ai_gain_16, + ai_speed:2000, + n_aochan:2, + aobits: 12, + ao_fifo_depth:2048, + .ao_range_table = &range_ni_E_ao_ext, + ao_unipolar:1, + ao_speed:1000, + has_8255:0, + .num_p0_dio_channels = 8, + caldac: {ad8804_debug}, + }, + {device_id:39, + isapnp_id:0x2700, + name: "at-mio-16xe-50", + n_adchan:16, + adbits: 16, + ai_fifo_depth:512, + alwaysdither:1, + gainlkup:ai_gain_8, + ai_speed:50000, + n_aochan:2, + aobits: 12, + ao_fifo_depth:0, + .ao_range_table = &range_bipolar10, + ao_unipolar:0, + ao_speed:50000, + .num_p0_dio_channels = 8, + caldac: {dac8800, dac8043}, + has_8255:0, + }, + {device_id:50, + isapnp_id:0x0000,/* XXX unknown */ + name: "at-mio-16xe-10", + n_adchan:16, + adbits: 16, + ai_fifo_depth:512, + alwaysdither:1, + gainlkup:ai_gain_14, + ai_speed:10000, + n_aochan:2, + aobits: 16, + ao_fifo_depth:2048, + .ao_range_table = &range_ni_E_ao_ext, + ao_unipolar:1, + ao_speed:1000, + .num_p0_dio_channels = 8, + caldac: {dac8800, dac8043, ad8522}, + has_8255:0, + }, + {device_id:51, + isapnp_id:0x0000,/* XXX unknown */ + name: "at-ai-16xe-10", + n_adchan:16, + adbits: 16, + ai_fifo_depth:512, + alwaysdither:1, /* unknown */ + gainlkup:ai_gain_14, + ai_speed:10000, + n_aochan:0, + aobits: 0, + ao_fifo_depth:0, + ao_unipolar:0, + .num_p0_dio_channels = 8, + caldac: {dac8800, dac8043, ad8522}, + has_8255:0, + } +};
