The * comedi_rt_timer driver can be used to emulate commands for this * driver. */ #include "../comedidev.h" #include #include "8255.h" #include "8253.h" #include "das08.h" #define DRV_NAME "das08" #define DO_ISA IS_ENABLED(CONFIG_COMEDI_DAS08_ISA) #define DO_PCI IS_ENABLED(CONFIG_COMEDI_DAS08_PCI) #define DO_COMEDI_DRIVER_REGISTER (DO_ISA || DO_PCI) #define PCI_DEVICE_ID_PCIDAS08 0x29 #define PCIDAS08_SIZE 0x54 /* pci configuration registers */ #define INTCSR 0x4c #define INTR1_ENABLE 0x1 #define INTR1_HIGH_POLARITY 0x2 #define PCI_INTR_ENABLE 0x40 #define INTR1_EDGE_TRIG 0x100 /* requires high polarity */ #define CNTRL 0x50 #define CNTRL_DIR 0x2 #define CNTRL_INTR 0x4 /* cio-das08.pdf "isa-das08" 0 a/d bits 0-3 start 8 bit 1 a/d bits 4-11 start 12 bit 2 eoc, ip1-3, irq, mux op1-4, inte, mux 3 unused unused 4567 8254 89ab 8255 requires hard-wiring for async ai */ #define DAS08_LSB 0 #define DAS08_MSB 1 #define DAS08_TRIG_12BIT 1 #define DAS08_STATUS 2 #define DAS08_EOC (1<<7) #define DAS08_IRQ (1<<3) #define DAS08_IP(x) (((x)>>4)&0x7) #define DAS08_CONTROL 2 #define DAS08_MUX_MASK 0x7 #define DAS08_MUX(x) ((x) & DAS08_MUX_MASK) #define DAS08_INTE (1<<3) #define DAS08_DO_MASK 0xf0 #define DAS08_OP(x) (((x) << 4) & DAS08_DO_MASK) /* cio-das08jr.pdf "das08/jr-ao" 0 a/d bits 0-3 unused 1 a/d bits 4-11 start 12 bit 2 eoc, mux mux 3 di do 4 unused ao0_lsb 5 unused ao0_msb 6 unused ao1_lsb 7 unused ao1_msb */ #define DAS08JR_DIO 3 #define DAS08JR_AO_LSB(x) ((x) ? 6 : 4) #define DAS08JR_AO_MSB(x) ((x) ? 7 : 5) /* cio-das08_aox.pdf "das08-aoh" "das08-aol" "das08-aom" 0 a/d bits 0-3 start 8 bit 1 a/d bits 4-11 start 12 bit 2 eoc, ip1-3, irq, mux op1-4, inte, mux 3 mux, gain status gain control 4567 8254 8 unused ao0_lsb 9 unused ao0_msb a unused ao1_lsb b unused ao1_msb 89ab cdef 8255 */ #define DAS08AO_GAIN_CONTROL 3 #define DAS08AO_GAIN_STATUS 3 #define DAS08AO_AO_LSB(x) ((x) ? 0xa : 8) #define DAS08AO_AO_MSB(x) ((x) ? 0xb : 9) #define DAS08AO_AO_UPDATE 8 /* gainlist same as _pgx_ below */ static const struct comedi_lrange range_das08_pgl = { 9, { BIP_RANGE(10), BIP_RANGE(5), BIP_RANGE(2.5), BIP_RANGE(1.25), BIP_RANGE(0.625), UNI_RANGE(10), UNI_RANGE(5), UNI_RANGE(2.5), UNI_RANGE(1.25) } };
