I've been trying to get my touch display module working tonight.
I assembled it, connected it to my NDGO, tried a power-on test and saw no smoke (good)
The module did nothing - I wasnt that surprised, since I have no code loaded in the NDGO.
I grabbed fabien's repository from bitbucket, and compiled all the library modules (but 1) successfully with VS2010 ultimate.
However, when I try to compile Nwazet.Go.SD either directly, or through the NWazetDisplayModule sample which includes it, I get:
"the type or namespace name 'IO' does not exist in the namespace 'SecretLabs.NETMF' (are you missing an assembly reference?)"
I cant seem to find SecretLabs.NETMF.IO anywhere, and I am unable to build the NwazetDisplayModule sample (because I cant build Nwazet.Go.SD, because I cant find SecretLabs.NETMF.IO)
So.. my LCD Touch Display Module remains dark. I havent seen so much as a backlight yet. Can you help me out here?
I have the 4.2 micro framework, fabien's repository, VS2010 - am I missing something else?

Hi mtylerjr,
The Netduino v4.2 beta SDK should include the SecretLabs.NET.IO.dll assembly.
Download link for 4.2 beta SDK:
http://forums.netdui...?showtopic=2768
Directory where the assembly is installed:
C:\Program Files (x86)\Secret Labs\Netduino SDK\Assemblies\v4.2
Does that help?
All sockets on Netduino Go are powered off during boot. They are powered up after boot (or when you use the go!bus assemblies).
Chris
Thanks for the help, Chris. I was missing the Secret Labs Netduino SDK. That's kind of important
The demo works great now! Other than the fact that it is trying to load images from an SD card on Go!bus port 8, and you havent released the SD card module yet
This is very cool though. I just went and ordered more stuff from Nwazet!

I'm glad that you're up and running
This is very cool though.
Wait until you see what we have in store specifically for the touch display module... Stay tuned!
I just went and ordered more stuff from Nwazet!
...and I just shipped your new order.
Cheers,
-Fabien.

can the touchscreen be used without a stylus
Sure. All you need to do is to display widgets large enough so that you can touch them with a finger
what font support does the screen provide?
The screen has the following built-in proportional fonts:
- dejavusans9
- dejavusansbold9
- dejavusanscondensed9
- dejavusansmono8
- dejavusansmonobold8
- verdana14
- verdana9
- verdanabold14
Cheers,

So.. you have to tell me - Has anyone at Nwazet ever connected 8 LCD touch panels to one Netduino Go?
LOL! I'm afraid that the power supply on the netduino Go! would not let you draw that much unfortunately: the display draws ~85mA at rest (mostly the backlight) and ~126 mA @ peak. The resettable fuse on the Netduino Go! board will only let you draw up to 500 mA (limit imposed by the USB spec) before shutting down the board's power supply. Now, there's a way around it, but that's a discussion for another time ;-)
I can't wait to see what kind of fun things you're going to build with your display module...
Cheers,
-Fabien.

Wont Nwazet make a version that can accept an external power source? That seems like a nice thing to do with a module that requires lots of power
