Several 970 * major reasons exist why this caused major confusion for users: 971 * 1) The register values are _NOT_ in user documentation, but rather in 972 * arcane locations, such as a few register programming manuals that are 973 * increasingly hard to find and the NI MHDDK (comments in in example code). 974 * There is no one place to find the various valid values of the registers. 975 * 2) The register values are _NOT_ completely consistent. There is no way to 976 * gain any sense of intuition of which values, or even enums one should use 977 * for various registers. There was some attempt in prior use of comedi to 978 * name enums such that a user might know which enums should be used for 979 * varying purposes, but the end-user had to gain a knowledge of register 980 * values to correctly wield this approach. 981 * 3) The names for signals and registers found in the various register level 982 * programming manuals and vendor-provided documentation are _not_ even 983 * close to the same names that are in the end-user documentation. 984 * 985 * Similar, albeit less, confusion plagued NI's previous version of their own 986 * drivers. Earlier than 2003, NI greatly simplified the situation for users 987 * by releasing a new API that abstracted the names of signals/terminals to a 988 * common and intuitive set of names. 989 * 990 * The names below mirror the names chosen and well documented by NI. These 991 * names are exposed to the user via the comedilib user library. By keeping 992 * the names below, in spite of the use of CamelScript, maintenance will be 993 * greatly eased and confusion for users _and_ comedi developers will be 994 * greatly reduced. 995 */ 996 997 /* 998 * Base of abstracted NI names. 999 * The first 16 bits of *_arg are reserved for channel selection. 1000 * Since we only actually need the first 4 or 5 bits for all register values on 1001 * NI select registers anyways, we'll identify all values >= (1<<15) as being an 1002 * abstracted NI signal/terminal name. 1003 * These values are also used/returned by INSN_DEVICE_CONFIG_TEST_ROUTE, 1004 * INSN_DEVICE_CONFIG_CONNECT_ROUTE, INSN_DEVICE_CONFIG_DISCONNECT_ROUTE, 1005 * and INSN_DEVICE_CONFIG_GET_ROUTES. 1006 */ 1007 #define NI_NAMES_BASE 0x8000u 1008 1009 #define _TERM_N(base, n, x) ((base) + ((x) & ((n) - 1))) 1010 1011 /* 1012 * not necessarily all allowed 64 PFIs are valid--certainly not for all devices 1013 */ 1014 #define NI_PFI(x) _TERM_N(NI_NAMES_BASE, 64, x) 1015 /* 8 trigger lines by standard, Some devices cannot talk to all eight. */ 1016 #define TRIGGER_LINE(x) _TERM_N(NI_PFI(-1) + 1, 8, x) 1017 /* 4 RTSI shared MUXes to route signals to/from TRIGGER_LINES on NI hardware */ 1018 #define NI_RTSI_BRD(x) _TERM_N(TRIGGER_LINE(-1) + 1, 4, x) 1019 1020 /* *** Counter/timer names : 8 counters max *** */ 1021 #define NI_MAX_COUNTERS 8 1022 #define NI_COUNTER_NAMES_BASE (NI_RTSI_BRD(-1) + 1) 1023 #define NI_CtrSource(x) _TERM_N(NI_COUNTER_NAMES_BASE, NI_MAX_COUNTERS, x) 1024 /* Gate, Aux, A,B,Z are all treated, at times as gates */ 1025 #define NI_GATES_NAMES_BASE (NI_CtrSource(-1) + 1) 1026 #define NI_CtrGate(x) _TERM_N(NI_GATES_NAMES_BASE, NI_MAX_COUNTERS, x) 1027 #define NI_CtrAux(x) _TERM_N(NI_CtrGate(-1) + 1, NI_MAX_COUNTERS, x) 1028 #define NI_CtrA(x) _TERM_N(NI_CtrAux(-1) + 1, NI_MAX_COUNTERS, x) 1029 #define NI_CtrB(x) _TERM_N(NI_CtrA(-1) + 1, NI_MAX_COUNTERS, x) 1030 #define NI_CtrZ(x) _TERM_N(NI_CtrB(-1) + 1, NI_MAX_COUNTERS, x) 1031 #define NI_GATES_NAMES_MAX NI_CtrZ(-1) 1032 #define NI_CtrArmStartTrigger(x) _TERM_N(NI_CtrZ(-1) + 1, NI_MAX_COUNTERS, x) 1033 #define NI_CtrInternalOutput(x) \ 1034 _TERM_N(NI_CtrArmStartTrigger(-1) + 1, NI_MAX_COUNTERS, x) 1035 /** external pin(s) labeled conveniently as Ctr<i>Out. */ 1036 #define NI_CtrOut(x) _TERM_N(NI_CtrInternalOutput(-1) + 1, NI_MAX_COUNTERS, x) 1037 /** For Buffered sampling of ctr -- x series capability. */ 1038 #define NI_CtrSampleClock(x) _TERM_N(NI_CtrOut(-1) + 1, NI_MAX_COUNTERS, x) 1039 #define NI_COUNTER_NAMES_MAX NI_CtrSampleClock(-1) 1040 1041 enum ni_common_signal_names { 1042 /* PXI_Star: this is a non-NI-specific signal */ 1043 PXI_Star = NI_COUNTER_NAMES_MAX + 1, 1044 PXI_Clk10, 1045 PXIe_Clk100, 1046 NI_AI_SampleClock, 1047 NI_AI_SampleClockTimebase, 1048 NI_AI_StartTrigger, 1049 NI_AI_ReferenceTrigger, 1050 NI_AI_ConvertClock, 1051 NI_AI_ConvertClockTimebase, 1052 NI_AI_PauseTrigger, 1053 NI_AI_HoldCompleteEvent, 1054 NI_AI_HoldComplete, 1055 NI_AI_ExternalMUXClock, 1056 NI_AI_STOP, /* pulse signal that occurs when a update is finished(?) */ 1057 NI_AO_SampleClock, 1058 NI_AO_SampleClockTimebase, 1059 NI_AO_StartTrigger, 1060 NI_AO_PauseTrigger, 1061 NI_DI_SampleClock, 1062 NI_DI_SampleClockTimebase, 1063 NI_DI_StartTrigger, 1064 NI_DI_ReferenceTrigger, 1065 NI_DI_PauseTrigger, 1066 NI_DI_InputBufferFull, 1067 NI_DI_ReadyForStartEvent, 1068 NI_DI_ReadyForTransferEventBurst, 1069 NI_DI_ReadyForTransferEventPipelined, 1070 NI_DO_SampleClock, 1071 NI_DO_SampleClockTimebase, 1072 NI_DO_StartTrigger, 1073 NI_DO_PauseTrigger, 1074 NI_DO_OutputBufferFull, 1075 NI_DO_DataActiveEvent, 1076 NI_DO_ReadyForStartEvent, 1077 NI_DO_ReadyForTransferEvent, 1078 NI_MasterTimebase, 1079 NI_20MHzTimebase, 1080 NI_80MHzTimebase, 1081 NI_100MHzTimebase, 1082 NI_200MHzTimebase, 1083 NI_100kHzTimebase, 1084 NI_10MHzRefClock, 1085 NI_FrequencyOutput, 1086 NI_ChangeDetectionEvent, 1087 NI_AnalogComparisonEvent, 1088 NI_WatchdogExpiredEvent, 1089 NI_WatchdogExpirationTrigger, 1090 NI_SCXI_Trig1, 1091 NI_LogicLow, 1092 NI_LogicHigh, 1093 NI_ExternalStrobe, 1094 NI_PFI_DO, 1095 NI_CaseGround, 1096 /* special internal signal used as variable source for RTSI bus: */ 1097 NI_RGOUT0, 1098 1099 /* just a name to make the next more convenient, regardless of above */ 1100 _NI_NAMES_MAX_PLUS_1, 1101 NI_NUM_NAMES = _NI_NAMES_MAX_PLUS_1 - NI_NAMES_BASE, 1102 }; 1103 1104 /* *** END GLOBALLY-NAMED NI TERMINALS/SIGNALS *** */ 1105 1106 #define NI_USUAL_PFI_SELECT(x) (((x) < 10) ?
