EASYEST LX can be used interactively - for quick troubleshooting and system prototyping. It also - offers record and playback capabilities that allow you to - create and replay automated sequences of operations. - - THE EASYEST LX DEMO SYSTEM - - The demo system is a subset of the complete EASYEST LX - system. - - Certain features have been limited. An example is data set - size, which is 128 points in the demo vs. 4096 points (more- for acquisition to disk) in the full system. - - All functions having to do with file I/O or printing have - been disabled, including scroll from disk. PID control, - Plotter Output, PCX Output, Transducer Calibration, and - A/D to Disk have also been disabled. It is still possible - to access the dialog boxes for these functions. - - Acquisition is simulated by a software routine called the - DASDEMO, which acts just like an acquisition board. DASDEMO- allows you to simulate acquiring data from up to 4 - channels, starting with channel 0. Channel 0 contains a - sine wave, channel 1 a noisy sine wave, channel 2 a - sawtooth wave, and channel 3 an EKG wave. DASDEMO also - allows you to simulate digital I/O. EASYEST LX acquires - data at maximum hardware speeds for all supported - boards. - - EASYEST LX ENVIRONMENT OVERVIEW - - EASYEST LX's screen displays a menu along the top of the - screen with icons along the other three sides. The large - center portion of the screen is for data display. Menu - items, icons, and dialog boxes are used to communicate with- the EASYEST LX program. - - MENU ITEMS - - The seven items on the menu at the top of the screen - provide a convenient way to perform system operations and - to set system parameters. Press the LEFT mouse button on a - menu item to select that menu item. To display on-screen - help for a menu item, select the item with the RIGHT mouse - button. - - ICONS - - Icons are used to initiate EASYEST LX's data acquisition, - analysis, graphics, and output functions. Most output - functions, including plotter, printer, data file, and PCX - file output have been disabled in the Demo System. A short - description of each outer border icon is displayed in the - bottom right corner of the screen when the mouse pointer - is positioned on that icon. An icon is selected by pressing- the LEFT mouse button when the pointer is positioned on the- icon. Selecting an icon initiates that icon's function. - To display on-screen help for an icon, point to that icon - and press the RIGHT mouse button - - MEMORY LOCATIONS - - EASYEST LX stores data in memory locations and permits - access to data via memory icons. The memory icons are - located to the left of the large center portion of the - screen and are labeled 0 - 15. Data acquired using the A/D - icon is stored in the memory location corresponding to its - channel number. For example , data acquired from channel 3 - is stored in memory location 3. Another memory location - labeled T for Temporary is used to store results of - analysis and interactive graphics operations. Memory - manipulation icons SAVE, To T, SUB, etc. allow you to move - data from one memory location to another. - - Note: Each memory location has a 'Y' and an 'X' data pair. - When data is acquired, the collected 'Y' data is - stored in a memory location along with the 'X' TIME - information. - - You can make a memory current by pointing to the memory - icon with the mouse and clicking the LEFT mouse button. A - yellow border will then be displayed around the icon. The - SAVE icon copies the contents of the T memory to the - currently selected memory. The To T icon copies the - contents of the current memory to the Temporary memory. The- SUB icon extracts a sub-section of the array in the current- memory location and stores the result in the T memory - location. - - Any operation to be performed on data, such as calculating - a derivative or plotting data, is performed on the current - memory location. - - - - DIALOG BOXES - - Dialog boxes with input fields appear on the screen when - the system needs to display information or when the system - requires additional information. - - Blue text in a dialog box is reporting information and - cannot be changed. Yellow text lists parameters such as - acquisition rate which can be changed. Yellow text is also - used to initiate actions, such as 'OK' to exit a dialog box- and execute its functions. (Colors are for EGA/VGA color - monitor with default color settings.) - - The value of an input box can be changed in two ways. Some - input boxes allow keyboard input and others require that - you click on the input to step through possible choices. - Most dialog boxes contain OK and Cancel buttons. Selecting - OK (or pressing ENTER) accepts the values that appear in - the input fields, closes the dialog box, and executes the - operation. Selecting Cancel (or pressing ESC) restores the - input field values to their previous values and closes the - dialog box without executing any operation. - - Most icon dialog boxes contain an input field located in - the bottom right corner of the box. This selection can be - toggled between On and Off, selecting whether the dialog - box is to be displayed during the playback of a recorded - sequence. When not recording a sequence, this selection is - ignored. - - MENU BAR OPTIONS - - MENU ITEM - Devices - - Use the Devices menu item to specify the voltage range and - scaling algorithm used in converting to engineering units - for each A/D channel. A different voltage range and scaling- algorithm can be used with each channel. Note that the DAS-- DEMO driver scales all channels to the voltage range set - for the first channel. Therefore, in EASYDEMO, each channel- will be scaled similarly. The EASYEST LX demo system has - the thermocouple scaling disabled. EASYEST LX only works - with a demonstration driver called DASDEMO. The DASDEMO - driver emulates a 4 channel data acquisition board. - - A transducer calibration routine is also available under - the Devices menu option. This routine can be used to - generate the polynomial coefficients which are used to - compute the physical units measured by the transducer from - the voltage acquired from the DAS board's A/D channel. - - MENU ITEM - Printer - - The Printer menu item displays a list of over 300 supported- printers. The user can select the printer type as well as - the DOS device to receive all printer information. Valid - DOS devices include LPT1, LPT2, COM1, COM2, valid DOS - filenames, and any other DOS device. Printer output has - been disabled in the demo system. - - MENU ITEM - Plotter - - EASYEST LX supports plotters that understand HPGL - (Hewlett Packard Graphics Language). Plotter output can be - directed to COM1 or COM2. Plotter output can also be - directed to a file through the HPGL icon. Plotter output - has been disabled in the demo system. - - MENU ITEM - Board - - The Board menu item displays the software configuration of - your current data acquisition board as specified by the - external DAS driver. The EASYEST LX demo system allows - only the DASDEMO board driver to be used. - - MENU ITEM - Style - - Use the Style menu item to specify parameters that affect - the appearance of graphs. When recording sequences, keep - in mind that all current styles are saved with the graphics- commands. This feature allows you to switch styles inside - a sequence. - - MENU ITEM - Edit - - Use the Edit menu item to edit ASCII files (including - sequence files). The editor can be used while recording a - sequence to remove unwanted commands; however, the edit - option is not recorded in the sequence. The Edit feature - has been disabled in the EASYEST LX demo system. - - MENU ITEM - Quit - - Use the Quit menu item to exit to DOS. When EASYEST LX is - exited, all options in the Devices, Printer, Plotter, and - Style menus are saved in a configuration file. Next time - you use EASYEST LX, this file is used to set up the system - as it had been when you last exited it. - - RECORD/PLAYBACK ICONS - These icons are located in the upper-left portion of the - EASYEST LX screen. They are used to record and play back - sequences created in EASYEST LX. - - RECORD Icon - - Use this icon to create sequences of operations for - automated playback. Clicking on this icon toggles "RECORD" - on and off. When "RECORD" is on (icon is red), all icon - selections and parameters are saved to your specified file.- Sequences can be run using "PLAYBACK", or assigned to - function keys with the Fn option. - - PLAYBACK Icon - - Select this icon to begin playback of a recorded sequence. - The playback light is on while playback is in progress and - off when playback is complete or is not active. - - VIEW Icon - - Select this icon to quickly and easily view the basic steps- of a recorded sequence without entering the editor. To - delete a sequence command, click on the command you wish to- delete and select Delete. Only the outline of a sequence is- displayed; that is, just the names of the icons selected. - Thus, individual parameters related to the icons are not - listed. Selecting View does not generate or modify a - sequence command. Thus, you can use View while recording a - sequence to examine what has been recorded so far and to - delete any erroneous steps in the sequence. - - FLOW Icon - - Select this icon to quickly and easily view a flowchart - of a recorded sequence. Flow provides a pictorial - representation of the information in View. The print option- is disabled in the EASYEST LX demo system. - - Graph Area Icons - - The graph area icons are located to the upper right of the - large center portion of the screen. Use the graph area - icons to specify the graph area for data display or for - screen output to file, plotter, or printer. The user can - select between 7 different graph areas; upper-right, - upper-left, lower-right, lower-left, upper-half, - lower-half, or full screen. - - Axis Type Icons - - The Axis Type icons are located to the lower right of the - large center portion of the screen. The seven axis types - draw the axes depicted on the icons. The last three axis - types allow for two vertical axes with different label - ranges. To specify a second Y axis range, plot a data set - using one of the last three axis type icons. Select the - Plot Axes icon to open the axis plot parameters dialog box - and change the Vertical Axis minimum and maximum values to - set the new range. Then overlay a data set using the - overlay data plot icon. The new data is plotted using the - new Y range. - - DATA ACQUISITION ICONS - - The six data acquisition icons are located in the upper - left side of the EASYEST LX screen. The data acquisition - icons perform A/D, D/A, digital I/O, strip chart - recording, PID loop control, and high speed A/D to disk. - - A/D Icon - - Select this icon to acquire from 1 to 4096 data points per - channel into memory locations 0 through 15. All 16 channels- can be sampled, with up to 16k points of data acquired in - one burst. When reading from multiple channels, all - channels must sample the same number of points. For example- you can acquire 1k points on 16 channels or 4k points on 4 - channels. Data from channel 0 is automatically stored in - memory location 0, channel 1 in memory location 1, etc. - The EASYEST LX demo system only allows 128 data points per - channel. - - The A/D icon can collect at the maximum rate of the data - acquisition board being used. EASYEST LX supports DMA, - external clocking, and external triggering for data - acquisition boards that have the hardware capability. - - D/A Icon - - Select this icon to output up to 4096 points per channel - from memory locations 0 through 15. Data from memory - location 0 is output to channel 0, memory location 1 to - channel 1, etc. - - Digital I/O Icon - - Select this icon to read from or output to the DAS board's - digital port(s). EASYEST LX supports all available digital - bits. - - Strip Chart Icon - - Select this icon to acquire and display up to eight - channels of data starting at any of up to 16 channels on - your data acquisition board. Data may also be directed to a- disk file (option not available in the demo system). If the- strip chart time duration is set to zero, the strip chart - will run until a key is pressed or left mouse button is - clicked. - - PID Icon - - Select this icon to perform either single point PID - (Proportional Integral Derivative) control or PID tuning. - PID can be used to aid in the control of a dynamic system - by outputting a signal that is related to the difference - between the desired and the actual values. PID control is - disabled in the EASYEST LX demo system. - - The single point PID allows you to perform up to 16 PID - loop calculations at one time. The number of D/A channels - available on your hardware determines how many PID loops - can be running, with a maximum of 16. Using the single - point PID allows you to perform other EASYEST LX - operations while the PID control is running. - - The PID tuner will allow you to run one PID loop. You - can alter the P, I, and D parameters as well as the - setpoint while the PID calculations are taking place. - The tuner also displays a strip chart of the setpoint - value and the signal that is being controlled by the - PID calculation. - - A/D to File Icon - - Select this icon to acquire data to a binary data file. - The data is converted to an EASYEST format when read back - via the Scroll from Disk Icon or File I/O Icon. EASYEST - LX can collect and store data from up to 16 channels into - data files as large as 32 Mbytes. Each data point requires - 4 bytes. Your data acquisition board must have DMA - capabilities in order to use the A/D to File Icon. The - EASYEST LX Demo System has the A/D to File Icon disabled. - - ANALYSIS ICONS - - EASYEST LX allows you to perform analysis on your data - interactively or in an automated sequence. The following - analysis icons are available in EASYEST LX. - - FFT Icon - - Selecting this icon performs either a forward or inverse - Fast Fourier Transform. The forward FFT decomposes a signal- into its periodic component waves of various frequency and - amplitude. The inverse FFT combines the component - frequencies into a signal. - - If a forward transform is selected the FFT is performed - on the currently selected memory location and the result - is returned to the T memory location. If inverse transform - is selected, the amplitude must be in the currently - selected memory location and the phase information must - be in the T memory location. The IFFT result is placed in - the T memory location. - - Peak Icon - - Select this icon to find local maxima or minima in the - data, using a least square quadratic fit method. The - algorithm uses a quadratic fit in the search for peaks - (or valleys) to differentiate between noisy spikes and - actual, parabolic-shaped peaks (or valleys). - - For the algorithm to detect true peaks or valleys rather - than local fluctuations due to noise, the user must enter - the approximate number of points that define a peak or - valley. - - Digital Filters Icon - - Select this icon to perform a filter operation in the time - domain. This filter is useful for removing unwanted signal - frequency components. For example, a low pass filter is - useful for removing high frequency noise, and a high pass - filter is useful for removing low frequency baseline drift.- The filter is created by EASYEST LX by multiplying an ideal- filter impulse response by a Blackman window. - - The available filter types are low pass, high pass, or - band pass. You must specify the filter type, the cutoff - frequency (for band pass, the upper and lower cutoff - frequencies), and the transition width (the region where - the filter response drops off). - - Statistics Icon - - Select this icon to perform up to nine statistical analyses- on data in the current memory location. The results of the - analyses are placed in the T memory location and can also - be displayed in one of the graph area quadrants. You can - select the desired operations to be performed from the - following list: - Minimum - Maximum - Mean - Sum - Median - Variance - Standard Deviation - Sum of Squares - Root Mean Square - - Integrate Icon - - Select this icon to perform numerical integration using the- 1/3 Simpson's rule. - - Differentiate Icon - - Select this icon to perform a first order derivative. The - derivative is computed by finite differences. No dialog box- is used with this operation. When the icon is selected the - operation is immediately performed on the currently - selected data set and the result is placed in the T memory - location. - - Curve Fit Icon - - Select this icon to perform a linear or a polynomial curve - fit. The fitted curve is returned to the T memory location.- The user also has the option of displaying the fit equation- to the screen. - - Arithmetic Operations Icon - - Select this icon to perform binary, unary, and array - creation operations; only one of these operations may be - performed at a time. The selected option is highlighted - a different color than the other options. - - Binary Operations - EASYEST LX uses the currently selected memory location and - the T memory location for the two operands which are - required for a binary operation. The result of the - operation is returned to the T memory location. The - available binary operations include addition, subtraction, - multiplication, division, and exponentiation. - - Unary Operations - Unary operations work on the currently selected memory - location and return the results to the T memory location. - The available unary operations include exponential, natural- log, logarithm, square root, mean, current memory size, - sine, cosine, tangent, max value, min value, convert time - base to index value, data clip to a specified value, and - create a ramped array of a specified size. - - The user may also specify the trigonometric units: radians,- degrees, and gradians. - - DATA DISPLAY ICONS - - Use the data display icons to display data either - graphically or numerically. The color of the data trace for- graphically displayed data is specified by selection of a - color on the Color Bar. - - Data Plot Icon - - Select this icon to plot the currently selected memory - location vs. the x-values for that memory location. This - icon uses an auto scaling routine to compute the axis - minimum and maximum values. You can alter the plot style - from the Style option on the menu bar. - - Overlay Data Plot Icon - - Select this icon to overlay a plot of the currently - selected memory location in the current graph area. The - current graph area must have had a Data Plot or an Axis - Plot before an Overlay Data Plot can be performed. - - X-Y Plot Icon - - Select this icon to draw a plot of the data in the T memory- location versus the data in the current memory location - using the axes specified by the style dialog box. - - Axis Plot Icon - - Select this icon to draw a set of axes as specified by the - style dialog box. The specified axes are drawn in the - current graph area. Use the Overlay Data Plot icon to plot - the desired data using these axes. Selecting this icon - opens the Axis Plot Parameters dialog box containing the - following horizontal and vertical input fields: - - Axis Minimum - Axis Maximum - Number of divisions - Labels on which tick - - This icon is useful for plots with multiple axes or for - doing multiple plots on a set scale. - - Waterfall Plot Icon - - Select this icon to draw a plot of 2 to 16 consecutive - memory locations cascaded on one pseudo three-dimensional - plot. The memories plotted must all be the same size; - otherwise, a message is returned stating invalid memories - have been specified. If the memory locations used contain - a small number of points (less than 15), the resulting plot- may be drawn off the edge of the plotting area. Waterfall - plots are useful for comparing different runs on the same - channel or data acquired on multiple channels during a - single acquisition. - - Scroll from Memory Icon - - Select this icon to scroll through a plot of the data - stored in the current memory location. Any memory, - including location T, can be used. When finished scrolling,- the segment that appears on the screen is stored in T. - Selecting this icon displays five scroll icons to which - mouse actions are limited. Note that there must be at least- 70 data points to use the scroll from memory icon. - - RIGHT ARROW: Select this icon to scroll the data to the - right as long as the left mouse button is depressed. - Index values are updated in the lower right corner of - the screen. - - LEFT ARROW: Select this icon to scroll the data to the left- as long as the left mouse button is depressed.
