28 MI.20xx Manual C/C++ Driver Interface Software C/C++ Driver Interface C/C++ is the main programming language for which the drivers have been build up. Theref ore the interface to C/C++ is the best m atch . All the small examples of the manual showing different parts of the hard ware programming are done with C.
Software C/C++ Driver Interface (c) Spectrum GmbH 29 Other Windows C/C++ compilers Include Driver To access the driver, the driver functions must be loaded from the driver dll. This can be easily done by standard windows func tions. There is one example in the directory /Examples/ other that shows the process.
30 MI.20xx Manual C/C++ Driver Interface Software Function SpcSetPa ram All hardware settings are based on software registers that can be set by the function SpcSetParam. This function sets a registe r to a defined value or executes a command. The board must first be initialized.
Software C/C++ Driver Interface (c) Spectrum GmbH 31 Under Linux the additional parameter nBytesPe rSample must be used for this function. For all boards with 8 bit resolution the p arameter is „1“, for all boards with 12, 14 or 16 bit resolution this paramet er has to be „2“.
32 MI.20xx Manual Delphi (Pascal) Programming Interface Software Delphi (Pascal) Pr ogramming Interface Type definiti on All Spectrum driver functions are using pr e-defined variable types to cover different operating systems and to use the same dri ver interface for all programming languages.
Software Delphi (Pascal) Programming Interface (c) Spectrum GmbH 33 This function is only available on generator or i/o boar ds. The function is not available on acquisition boards. Function SpcGetData Reads data from the board from a specific me mo ry channel.
34 MI.20xx Manual Visual Basic Programming Interface Software Visual Basic Prog ramming Interfa ce The Spectrum boards can be used together with Microsoft Visual Ba sic as well as with Microsoft Visual Basic for Applications. T his allows per example the direct access of the hardwa re from within Microsoft Ex cel.
Software Visual Basic Programming Interface (c) Spectrum GmbH 35 Function SpcGetParam The function SpcGetParam reads out software registers or status information. The board must first be initialized. The available software re- gisters for the driver are listed in the board specific part of th e documentation below.
36 MI.20xx Manual Overview Programming the Board Programming the Board Overview The following chapters show you in detail how to program the different aspects of the board. For every topic there’s a small ex ample. For the examples we focussed on Visual C++.
Programming the Board Initialization (c) Spectrum GmbH 37 This means as a result that it is not nece ssary to check each driver call for an error but to check for an error before the boa rd is started to see whether all settings ha ve been vali d. By reading all the error information one can easily examine wher e the error occure d.
38 MI.20xx Manual Initialization Programming the Board Hardware versi on Since all of the MI, MC and MX boards from Spectrum are modular boards, they consis t of one base board and one or two (only PCI and CompactPCI) piggy-back modules. This register SPC_PCIVERSION gi ves information about the revision of either the base board and the mo- dules.
Programming the Board Initialization (c) Spectrum GmbH 39 Installed features and options The SPC_PCIFEATURES register informs you about the options, that are installed on the b oard. If you want to know about one opti on being installed or not, you need to read out the 32 bit value and mask the interesting bit.
40 MI.20xx Manual Powerdown and reset Programming the Board Example program for the board initialization The following example is only an exerpt to give you an idea on how easy it is to initialize a Spectrum board. Powerdown and reset Every Spectrum board can be set to powerdown mode by software.
Analog Inputs Channe l Selection (c) Spectrum GmbH 41 Analog Inputs Channel Selection One key setting that influences all other possible settings is th e channel enable register. An unique feature of the Spectrum b oards is the possibility to program the number of channels you want to use.
42 MI.20xx Manual Setting up the inputs Analog Inputs Setting up the inputs Input ranges This analog acquisition board uses separate input amplifiers and converters on each ch annel. This gives you the possibility to set up the de- sired and concerning your application best suiting input range also separately for each ch annel.
Analog Inputs Setting up the inputs (c) Spectrum GmbH 43 Input offset In most cases the external signals will not be symm etrically re- lated to ground. If you want to acquire such as ymmetrical sig- nals, it is possible to use the smallest input range that matches the biggest absolute signal am plitude without exceeding the range.
44 MI.20xx Manual Setting up the inputs Analog Inputs Input termination All inputs of Spectrum’s analog boards can be terminated separately with 50 Ohm by so ftware programming. If you do so, please m ake sure that your signal source is able to deliver the higher output currents.
Standard acquisition modes General Information (c) Spectrum GmbH 45 Standard acquisition modes General Information The standard mode is the easiest and mostly used mode to acquire analog data with a Spectrum A/D board.
46 MI.20xx Manual Programming Standard acquisition modes The values depend on the number of activa ted channels and on the type of board being used. The minimum stepsizes for setting up the mem- size and the postcounter are shown in the table below.
Standard acquisition modes Programming (c) Spectrum GmbH 47 Command register If the board is started in the interrupt mode the task calling the start function will not return until the board has finished.
48 MI.20xx Manual Programming Standard acquisition modes Please refer to the relating chapter earlier in this manual. Th e examples in this section are written in Visual C++ for Windows , so the examples differ a little bit for the use with linux.
FIFO Mode Overview (c) Spectrum GmbH 49 FIFO Mode Overview General Information The FIFO mode allows to record data continuously and trans- fer it online to the PC (acquisi tion boards) or allows to write data continuously from the PC to the board (generation boards).
50 MI.20xx Manual Programming FIFO Mode When using FIFO mode together with one of the options that allow to have gaps in the acquisiton like Multiple Recording or Gate d Sampling one can even run the board with higher sample rates.
FIFO Mode Programming (c) Spectrum GmbH 51 Analog acquisition or generation boards Digital I/O (701x or 702x ) or pattern generator boards (72xx) Digital I/O board 7005 only We at Spectrum achieved best results when programming the buffer leng th to a number of samples that can hold approximately 100 ms of data.
52 MI.20xx Manual Programming FIFO Mode FIFO mode In normal applications the FIFO mode will run in a loop and process one buffer after the other. There are a few special command s and regi- sters for the FIFO mode: The start command and the wait command both wa it for the signal from the driver that th e next buffer has to be processed.
FIFO Mode Programming (c) Spectrum GmbH 53 The following example shows how to sort the channel data when us ing 4 channels in FIFO mode: Sample for mat The sample format in FIFO mode does not differ from the one of the standard (non FIFO) mode. Please refer to the relating passa ge concerning the sample format in the st andard acquisition chapter.
54 MI.20xx Manual Overview Clock generation Clock generation Overview The Spectrum boards offer a wide variety of different clock mode s to match all the customers need s.
Clock generation Internally generated sample rate (c) Spectrum GmbH 55 Maximum internal sample rate in MS/s Using plain quartz with no PLL In some cases it is useful for the application not to have the on-board PLL activated.
56 MI.20xx Manual Internally generated sample rate Clock generation Termination of the clock input If the external connector is used as an in put, either for fee ding in an external reference clock or for external clocking you c an enable a 50 Ohm termination on the board.
Clock generation Internally generated sample rate (c) Spectrum GmbH 57 External cloc k with divide r The extra clock divider can be used to divide an external fed in clock by a fixed value. The exte rnal clock must be > 1 MS/s. T his divided clock is used as a sample clock for the board.
58 MI.20xx Manual General Description Trigger modes and appendant registers Trigger modes and appendant registers General Description The trigger modes of the Spectrum MI, MC an d MX A/D boards are very complex and give yo u the possibility to detect nearly any t rigger event, you can think of.
Trigger modes and appendant registers External TTL trigger (c) Spectrum GmbH 59 If you choose an external trigger mode th e SPC_TRIGGEROUT register will be overwri tten and the trigger connector will be used as an input anyways. As the trigger connector is used as an input, y ou can decide wh ether the input is 50 Ohm terminated or not.
60 MI.20xx Manual External TTL trigger Trigger modes and appendant registers Positive and negative TTL trigger This mode is for detecting the ri sing and falling edges of an ex- ternal TTL signal. The board will trig ger on the first rising or falling edge that is detected after starting the board.
Trigger modes and appendant registers External TTL trigger (c) Spectrum GmbH 61 TTL pulsewidth trigger for long LOW pulses This mode is for detecting LOW pu lses of an external TTL signal that are longer than a programm ed pulsewidth. If the pulse is shorter than the programmed pulsewidth, no trigger will be detec- ted.
62 MI.20xx Manual Channel Trigge r Trigger modes and appendant registers Channel Trigger Overview of the channel tri gger registers The channel trigger modes are the most common modes, compared to external eq uipment like osc ill oscopes. The 17 different channe l trigger modes enable you to observe nearly any part of the analog signal.
Trigger modes and appendant registers Channel Trigger (c) Spectrum GmbH 63 Triggerlevel All of the channel trigger modes listed above require at least one triggerlevel to be set (except TM_CHXOFF of course). Some li ke the window trigger require even two levels (upper and lo wer level) to be set.
