Windmill News: Survey Results
________________________________________________________

If you completed last month's survey - many thanks. 
It's still not too late if you wish to send us your 
opinions: the questions are now on the web site at 
http://www.windmill.co.uk/monitor42.html

How we used your Survey Responses
=================================

All suggestions for improving the software have been 
passed to Windmill's managing director for his 
consideration. We received a varied list of items 
you'd like to see covered in Monitor, which we've 
summarised below. We also had a few questions on 
using the software - see later for the answers.

Wish List of Topics to be Covered in Monitor
============================================

Our survey produced many suggestions for future 
Monitor topics, which we've categorised here under 
5 topics. 

1. Application Stories
   Several people wanted real-world examples of how 
   Windmill is being used. To make this a regular 
   feature we need your input: please tell us about how 
   Windmill is helping your project. E-mail the editor 
   at [email protected]

2. Using Windmill
   This was another popular category of request. 
   Suggestions included "Getting started with the free 
   software" and "Trouble Shooting". We already have 
   quite a bit of information on using Windmill on the 
   web site. For instance, Issue 19 of Monitor had tips 
   on getting started with Windmill:
   http://www.windmill.co.uk/freesoftware.html
   and technical support answers at 
   http://www.windmill.co.uk/techsupp.html

   Details on using the individual Windmill programs are 
   in their on-line Help. For the latest versions of 
   the Help see
   http://www.windmill.co.uk/help.html

   If you feel these resources fall short, let us know.

3. Visual Basic and other Programming Tips
   We ran a series of "Visual Basic Corners" in earlier 
   editions of Monitor. These are archived at: 
   http://www.windmill.co.uk/monitor13.html
   http://www.windmill.co.uk/standard.html
   http://www.windmill.co.uk/rs-232.html
   http://www.windmill.co.uk/magazine.html
   http://www.windmill.co.uk/activex.html
   http://www.windmill.co.uk/monitor21.html

   If you have any VB tips you think would benefit our 
   readers, please send them in and we'll be pleased to 
   publish them.

4. Subjects Previously Covered
   Some suggestions were for topics we've already 
   covered, such as GPIB, choosing a data acquisition 
   system and USB. You can see a list of previous 
   Monitor editions at 
   http://www.windmill.co.uk/newsletter.html
   Plus we plan to provide a more comprehensive index 
   to all back issues in a future edition. If there 
   are subjects you think we haven't covered in enough 
   detail and could do with revisiting, let us know.

5. Other Suggestions
   We've noted all your topic suggestions and have 
   plenty to work on for coverage over the rest of 
   the year. 


Your Windmill Questions Answered
================================

Our survey raised a few questions on using Windmill. 
In some cases we've replied directly, others are 
answered here. You might also like to look at our 
on-line faq.

How to incorporate software gauges and graphs in Windmill?
  For software gauges you need the Windmill Graphics 
  program. With Graphics you draw a background in any 
  painting package and save it as a bitmap. You then 
  drop "live" items, like analogue gauges, onto the 
  background. For more details see
  http://www.windmill.co.uk/graphics.html
  For reviewing graphs of previously saved data use the 
  Windmill Replay program
  http://www.windmill.co.uk/replay.html
  For real-time graphing use the free Windmill Chart 
  program.

                            *

How to introduce ramp functions like those used in recipes for brewing beer?
  Ramp functions are provided by our Test-Seq software. 
  This sends commands and data to other Windows 
  programs, or directly to the hardware inputs and 
  outputs. The command, or test sequence, file is a text 
  file which you can easily create in a text editor or 
  word processor. 
  Some typical Test-Seq operations
  - Monitor channels for alarms. 
  - Perform PID control. 
  - Display a dialogue box that lets the operator select 
    the next action. 
  - Wait until a value from an input channel complies with 
    that specified, for example Wait Temperature > 20. 
  - Change channel attributes, for example change the units 
    of a temperature channel from Celsius to Fahrenheit, 
    or the range of a voltage channel from ± 10 volts 
    to 0-10 millivolt. 
  - Ramp output values up and down. 
  For more details of Test-Seq see
  https://www.windmillsoft.com/daqshop/test-control.html

How to take out the fake instrument?
  The "fake instrument", or signal generator, lets you 
  play with Windmill without the need for any 
  measurement hardware to be attached to your computer. 
  To remove the signal generator:
  1. In the Windmill SetupIML program, open your 
     hardware setup file (*.ims).
  2. From the Mode menu choose Select Channels. 
  3. Double-click each of the SigGen channels. 
     They are now greyed-out and will be ignored by the 
     other Windmill programs like Logger and DDE Panel. 
  4. Save the *.ims file and close SetupIML. 

                            *

How to plot an xy diagram?
  The free Windmill Chart program plots data against 
  time. However, with Windmill you can collect data 
  from your device and send it in real-time to other 
  software like Excel. You can then create your 
  x-y diagrams in Excel. For more details see our Excel 
  interfacing and Excel charting pages.
