64 | Function Name : _INT_ i_APCI1710_InitChrono |
65 | (unsigned char_ b_BoardHandle, |
66 | unsigned char_ b_ModulNbr, |
67 | unsigned char_ b_ChronoMode, |
68 | unsigned char_ b_PCIInputClock, |
69 | unsigned char_ b_TimingUnit, |
70 | ULONG_ ul_TimingInterval, |
71 | PULONG_ pul_RealTimingInterval)
72
73 +----------------------------------------------------------------------------+
74 | Task : Configure the chronometer operating mode (b_ChronoMode)|
75 | from selected module (b_ModulNbr). |
76 | The ul_TimingInterval and ul_TimingUnit determine the |
77 | timing base for the measurement. |
78 | The pul_RealTimingInterval return the real timing |
79 | value. You must calling this function be for you call |
80 | any other function witch access of the chronometer. |
81 | |
82 | Witch this functionality from the APCI-1710 you have |
83 | the possibility to measure the timing witch two event. |
84 | |
85 | The mode 0 and 1 is appropriate for period measurement.|
86 | The mode 2 and 3 is appropriate for frequent |
87 | measurement. |
88 | The mode 4 to 7 is appropriate for measuring the timing|
89 | between two event. |
90 +----------------------------------------------------------------------------+
91 | Input Parameters : unsigned char_ b_BoardHandle : Handle of board APCI-1710 |
92 | unsigned char_ b_ModulNbr CR_AREF(insn->chanspec) : Module number to configure |
93 | (0 to 3) |
94 | unsigned char_ b_ChronoMode data[0] : Chronometer action mode |
95 | (0 to 7). |
96 | unsigned char_ b_PCIInputClock data[1] : Selection from PCI bus clock|
97 | - APCI1710_30MHZ : |
98 | The PC have a PCI bus |
99 | clock from 30 MHz |
100 | - APCI1710_33MHZ : |
101 | The PC have a PCI bus |
102 | clock from 33 MHz |
103 | - APCI1710_40MHZ |
104 | The APCI-1710 have a |
105 | integrated 40Mhz |
106 | quartz. |
107 | unsigned char_ b_TimingUnit data[2] : Base timing unity (0 to 4) |
108 | 0 : ns |
109 | 1 : µs |
110 | 2 : ms |
111 | 3 : s |
112 | 4 : mn |
113 | ULONG_ ul_TimingInterval : data[3] Base timing value. |
114 +----------------------------------------------------------------------------+
115 | Output Parameters : PULONG_ pul_RealTimingInterval : Real base timing |
116 | value.
117 | data[0]
118 +----------------------------------------------------------------------------+
119 | Return Value : 0: No error |
120 | -1: The handle parameter of the board is wrong |
121 | -2: Module selection wrong |
122 | -3: The module is not a Chronometer module |
123 | -4: Chronometer mode selection is wrong |
124 | -5: The selected PCI input clock is wrong |
125 | -6: Timing unity selection is wrong |
126 | -7: Base timing selection is wrong |

1303 +----------------------------------------------------------------------------+
1304 | Task : Return the chronometer status (pb_ChronoStatus) and the|
1305 | timing value (pul_ChronoValue) after a stop signal |
1306 | occur from selected chronometer module (b_ModulNbr). |
1307 | This function are only avaible if you have disabled |
1308 | the interrupt functionality. See function |
1309 | "i_APCI1710_EnableChrono" and the Interrupt mask |
1310 | description chapter. |
1311 | You can test the chronometer status witch the |
1312 | "i_APCI1710_GetChronoProgressStatus" function. |
1313 | |
1314 | The returned value from pul_ChronoValue parameter is |
1315 | not real measured timing. |
1316 | You must used the "i_APCI1710_ConvertChronoValue" |
1317 | function or make this operation for calculate the |
1318 | timing: |
1319 | |
1320 | Timing = pul_ChronoValue * pul_RealTimingInterval. |

1322 | pul_RealTimingInterval is the returned parameter from |
1323 | "i_APCI1710_InitChrono" function and the time unity is |
1324 | the b_TimingUnit from "i_APCI1710_InitChrono" function|

1328 +----------------------------------------------------------------------------+
1329 | Output Parameters : PULONG_ pb_ChronoStatus : Return the chronometer |
1330 | status. |
1331 | 0 : Measurement not started.|
1332 | No start signal occur. |
1333 | 1 : Measurement started. |
1334 | A start signal occur. |
1335 | 2 : Measurement stopped. |
1336 | A stop signal occur. |
1337 | The measurement is |
1338 | terminate. |
1339 | 3: A overflow occur. You |
1340 | must change the base |
1341 | timing witch the |
