The proper settings for these 25 * caldacs are stored on the board's eeprom. To read the caldac values 26 * from the eeprom and store them into a file that can be then be used by 27 * comedilib, use the comedi_calibrate program. 28 * 29 * Configuration options: none 30 * 31 * The daqcard-1200 has quirky chanlist requirements when scanning multiple 32 * channels. Multiple channel scan sequence must start at highest channel, 33 * then decrement down to channel 0. Chanlists consisting of all one channel 34 * are also legal, and allow you to pace conversions in bursts. 35 * 36 * NI manuals: 37 * 340988a (daqcard-1200) 38 */ 39 40 #include <linux/module.h> 41 42 #include "../comedi_pcmcia.h" 43 44 #include "ni_labpc.h" 45 46 static const struct labpc_boardinfo labpc_cs_boards[] = { 47 { 48 .name = "daqcard-1200", 49 .ai_speed = 10000, 50 .has_ao = 1, 51 .is_labpc1200 = 1, 52 }, 53 }; 54 55 static int labpc_cs_auto_attach(struct comedi_device *dev, 56 unsigned long context) 57 { 58 struct pcmcia_device *link = comedi_to_pcmcia_dev(dev); 59 int ret; 60 61 /* The ni_labpc driver needs the board_ptr */ 62 dev->board_ptr = &labpc_cs_boards[0]; 63 64 link->config_flags |= CONF_AUTO_SET_IO | 65 CONF_ENABLE_IRQ | CONF_ENABLE_PULSE_IRQ; 66 ret = comedi_pcmcia_enable(dev, NULL); 67 if (ret) 68 return ret; 69 dev->iobase = link->resource[0]->start; 70 71 if (!link->irq) 72 return -EINVAL; 73 74 return labpc_common_attach(dev, link->irq, IRQF_SHARED); 75 } 76 77 static void labpc_cs_detach(struct comedi_device *dev) 78 { 79 labpc_common_detach(dev); 80 comedi_pcmcia_disable(dev); 81 } 82 83 static struct comedi_driver driver_labpc_cs = { 84 .driver_name = "ni_labpc_cs", 85 .module = THIS_MODULE, 86 .auto_attach = labpc_cs_auto_attach, 87 .detach = labpc_cs_detach, 88 }; 89 90 static int labpc_cs_attach(struct pcmcia_device *link) 91 { 92 return comedi_pcmcia_auto_config(link, &driver_labpc_cs); 93 } 94 95 static const struct pcmcia_device_id labpc_cs_ids[] = { 96 PCMCIA_DEVICE_MANF_CARD(0x010b, 0x0103), /* daqcard-1200 */ 97 PCMCIA_DEVICE_NULL 98 }; 99 MODULE_DEVICE_TABLE(pcmcia, labpc_cs_ids); 100 101 static struct pcmcia_driver labpc_cs_driver = { 102 .name = "daqcard-1200", 103 .owner = THIS_MODULE, 104 .id_table = labpc_cs_ids, 105 .probe = labpc_cs_attach, 106 .remove = comedi_pcmcia_auto_unconfig, 107 }; 108 module_comedi_pcmcia_driver(driver_labpc_cs, labpc_cs_driver); 109 110 MODULE_DESCRIPTION("Comedi driver for National Instruments Lab-PC"); 111 MODULE_AUTHOR("Frank Mori Hess <fmhess@users.sourceforge.net>"); 112 MODULE_LICENSE("GPL"); 113
