Platform Invoke

This is where native code meets .NET.  Its very much a black art, lots of smoke and mirrors etc. etc… But a necessary evil with Windows CE.  That is because it is the gateway from .NET applications to the hardware and to the operating system.  This is the first of a series of blogs on this matter.

I must though give credit to others’ who shoulders I am standing on for this.  Whilst I have had experience with PInvoke going back to the first version of .NET CF on Windows CE (I think it was about V4.2) I have referenced a number of sources in an attempt to provide a comprehensive coverage of this topic.  I’ll provide a reading list and some links in a later blog.

Spark Kit LCD Display: Selection

I wanted to attach an LCD touch screen to the top of the kit.  The lid has a diagonal of about nine inches (22cm) so a 6, 7 or 8 inch screen will do.  The LCD The options are: A  portable LCD screen unit with a VGA interface such as: An LVDS LCD display such as: (From ICOP) A TFT Flat Panel Display such as: The first type is simplest as it requires no internal changes to the box.  These are priced at about $A400 upwards. The second type is more integrated into the system.  The Vortex86DX-Spark Kit has an LVDS socket on the processor board. The third type is even more integrated into the ...

LCD Screens and Touch

About Smartphones typically have an LCD graphical screen with touch input.  Touch is used to take user input via windows controls such as menus and command buttons.  A SIP (Software Input Panel) may also be used am on-screen keyboard.  Alternatively, some phones use a small physical keyboard.  Some use both.  Most touchscreens are single input, that is only one point of contact can be deciphered.  Multitouch is becoming a required feature.  Multitouch allows not only simple zoom and rotation of images, it allows quite complexes gestures.  Windows 7 supports Multitouch with suitable hardware.  A touchscreen has two uses.  One is as a pointing devices, that is as a mouse.  The other is to action gestures such as click, double click etc,  It can be used with a finger or stylus. Windows CE can support an LCD panel with a touchscreen; it has for many versions.  Windows CE 6 R3 supports single finger gestures.  My HTC phone (HTC HD2) support ...

embedded Spark 2010 Challenge: End of Round 2

I got my entry in with about 24 hours to spare: Twenty two entries were posted by the cut-off out of 75 in round 2.  Three now get chosen to present at ESC in Silicon Valley later this month. Being the Easter break (we have a 4 day weekend break over Easter: Friday to Monday) we were due to take a short vacation in the country but had to that delay that so that I could submit before leaving.  I had to quickly learn how to post a video on Youtube.  I used my phone to record some material, then edited it with Moviemaker.  I had to subscribe to a video converter because the phone’3G video format needed changing. My main implementation issue was that I only got the LVDS LCD panel at the last moment and discovered that I hadn’t ordered the touch screen version; and it required 12V that wasn’t available in the kit.  I wrote about these in the report and will blog all of this.  I got the touch panel tod ...
