Welcome to EASYEST LX ! -
-
EASYEST LX is an icon-driven data acquisition, analysis, -
and graphics program. 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. -

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,-

Select this icon to add a Yes/No command to the sequence -
file. When this command is encountered, the sequence -
execution is paused until [Y] or [N] is input from the -
keyboard. If [Y] is pressed, the subsequent sequence -
command is executed; if [N] is pressed, the next sequence -
command is ignored. Because no message command is used to -
indicate that the sequence is waiting for input, you may -
want to add a Message command before the Yes/No command -
in your sequence so that a message is printed to the -
screen before the sequence is paused. This feature is -
accessible only when record is on. -
-
EASYEST LX TOOLS -
-
EASYEST LX tools are utilities that do not generate or -
modify sequence commands and are therefore not saved in -
sequences; thus if a tool is selected while recording a -
sequence, the tool is not used when the sequence is played -
back and it does not appear anywhere in the sequence file. -
EASYEST LX tools include the color palette, help, waveform -
generator, function key programming, and the record icons -
View and Flow. -
-
Color Palette Icon -
-
Select this icon to change the EASYEST LX screen colors. -
Sixteen colors are listed with their color squares to the -
right. Selecting a color square toggles through 64 color -
choices. An individual color is returned to its default -
by selecting the D next to its name. All sixteen colors -
are returned to their defaults by clicking on the word -
Defaults. The selected colors are stored in a file and -
recalled upon beginning a session. Select monochrome to run-
EASYEST LX on a 16 shade gray scale monitor such as a gas -
plasma display. -
-
Help -
-
Selecting this button displays a Table of Contents and -
allows you to view on-line help. -
-
Wave Generator -
-
Select the Waveform Generator icon to create discrete -
value arrays of periodic and noise waveforms. These -
waveforms can be used anywhere in EASYEST LX. -
-
Waveforms created in the waveform generator are deleted -
when EASYEST LX is exited; therefore, you must save a -
waveform on disk to avoid losing it. -
-
Function Key Programming Icon -
-
Select this icon to program the function keys F1-F10 to -
load and execute a specified sequence when pressed. -
Pressing the right mouse button for help on the Fn -
icon opens the Show Function Keys dialog box, which -
lists the ten function keys and the sequences assigned -
to them. This information is automatically saved in -
a file. -
