Oh boy, I may not want to open such a perfectly packaged box!
Look forward to getting it!
It's alright, you have permission to open the box if you stop folding proteins

#16738 VB Example - Analog Inputs and PWM

Hi
What is the max value for "SetDutyCycle(x)"
// Nizze
its 100... i think if you put in anything higher it just sets it to 100 because it wont throw an exception.

I love the blinking digit! I feel like you're setting the time on a VCR(*).
Awesome.
Thanks for making and sharing this, Omar!

#16918 SD Card not working
Posted by Omar (OZ) on 21 August 2011 - 02:33 PM in Netduino Plus 2 (and Netduino Plus 1)
I think the SD card can be found at \SD rather than \\SD.
Regards,
Mark
You are correct, @"\SD\" is the same as "\\SD\\" but those two were mixed. I did give him some code which worked for me but it didn't work for him. So his SD card is bad, but that code is also bad. Good catch

#31560 Oz-Solutions Tutorial: RGB LED
Posted by Omar (OZ) on 04 July 2012 - 06:50 AM in Netduino 2 (and Netduino 1)
Guys,
I could use some help. We've built a netduino project similar to this one. But it doesn't work. I took this sample code and tried it too, doesn't work.
I grabbed a couple of AA batteries and put them in series to generate 3volts, then touched the contacts to my led to see if it's broken, and it works, but only if I reverse the polarity from what's in the diagram. What am i doing wrong?
I was connecting the negative side of the battery to longest lead (common) of the RGB LED. That won't light it up, but it will if I reverse the connection and put the positive to the common.
Have I done something wrong?
Rob
I think you've got a common anode LED. There is nothing you're doing wrong, just put the common lead into the 3V# instead of GND. this will also make it so SetDutyCycle(0) will turn them on, and SetDutyCycle(100) will turn them off. so its reversed.

#16885 Netduino USB HID Touch Screen Keyboard
Posted by Omar (OZ) on 20 August 2011 - 08:50 PM in Project Showcase
Wow Omar, you put a lot of work into this! Shift lock? Hover effects (and key cancellation if you move off)?
Cool!
Chris
(yes)
thanks!

#16325 Netduino USB HID Keyboard - Updated code
Posted by Omar (OZ) on 04 August 2011 - 01:21 PM in Project Showcase
I miss an episode...
Questions:
This project would let the Netduino app to read an USB-keyboard?
Was made with the official firmware? If not, could you provide the firmware for the Plus as well?
Thank you!
Sorry about that not everyone is on the same page, my bad. I will update the details above...
EDIT:
I listed a few steps up there. I hope it helps. and just to make it clear, the netduino wont become a host (read keyboard data) it will become a client (be a keyboard).

#19415 Netduino USB HID Keyboard - Updated code
Posted by Omar (OZ) on 19 October 2011 - 10:37 PM in Project Showcase
Hi,
Thanks for this!
I'm not sure where the official repository for keyboard.cs is - but I added single and double quote support:
case 34: // " cb = 52; mod = 0x02; break; case 39: // ' cb = 52; break;
This is a great reference if there are any keys you need to add for your project: http://www.quadibloc.com/comp/scan.htm
Thanks Again!
Dan
Thanks for the contribution! I'll add it to the code when i get some time.

#16315 Netduino USB HID Keyboard - Updated code
Posted by Omar (OZ) on 04 August 2011 - 09:36 AM in Project Showcase
Omar, would it also be possible to add something for combined combinations?
Yeah I am going to work on that. I just wanted to open it up now for people to play with and report bugs to me I don't think that the SendKey syntax will be implemented though, its a bit complex and would take a lot of parsing. I want to try and find an easier way to do it.
#16311 Netduino USB HID Keyboard - Updated code
Posted by Omar (OZ) on 04 August 2011 - 09:04 AM in Project Showcase
This will make the netduino a USB HID, so the netduino will simulate a keyboard in this case.
To get your netduino ready for this:
1 Install firmware 4.1.1 http://forums.netdui...re-v411-beta-1/
2. Transfer to Serial deployment http://forums.netdui...b-and-com1com2/
3. Create a project and put the class in it, add the test code to your program's main method
4. Hook up a usb to serial like this: http://www.sparkfun.com/products/9873 to your netduino's com1 or 2, which ever you chose while setting serial deployment
5. Change deployment in VS to Serial, select your com port
6. Power your netduino with a 9V battery or whatever, except usb. Deploy.
7. You need the code to run and set up the usb stream first, then connect your usb cable.
Class: Keyboard.cs 16.63KB 241 downloads
Add a reference to:
Microsoft.SPOT.Hardware.Usb
Sample use. As in the video.
string setupResult = Keyboard.SetUp(); Debug.Print(setupResult); if (setupResult != "Success") return; while (true) { led.Write(true); if (button.Read()) Keyboard.SendString("/*\n" + "* Supported Characters (with this method):\n" + "* abcdefghijklmnopqrstuvwxyz\n" + "* ABCDEFGHIJKLMNOPQRSTUVWXYZ\n" + "* 0123456789\n" + "* enter escape backspace deletethis\b\b\b\b\b\b\b\b\b\b \ttab space\n" + "* - = [ { ] } \\ | , > . < / ? ! @ # $ % ^ & * ( )\n" + "*/"); led.Write(false); Thread.Sleep(2000); }
Projects using the netduino as a keyboard coming sometime soon. I want to make a mouse class next.
I found this:
/* Custom USB HID Communication Device
* Copyright © Secret Labs LLC. All Rights Reserved.
*
*
* Licensed under the Apache 2.0 open source license
*/
in the original code from the USB HID example. I added that I expanded it. I am not big on licenses, but I think I must add it to my code as well. License info here: http://www.apache.or...ICENSE-2.0.html

#16590 Netduino and a touch screen as input interface
Posted by Omar (OZ) on 10 August 2011 - 10:18 PM in Netduino 2 (and Netduino 1)
Hello, as title, i need a 2,5" - 3,5" netduino compatible touch screen (with drivers) that act as input interface.
For example, at this moment on my netduino i've connected 16 realys and 2 74hc595 shift registers. All work well, i can act all i want relays (thanks to Stefan 74hc595 drivers) but now i have only output (yes and only one onboard input button), so i need input ... and if is possible this inputs must be virtual buttons (designed on touch screen) that acts my ralays. Exists this touch screen i need? where i can find and buy it? Thank you
The company 4D Systems has a few serial touch screens. http://www.4dsystems...au/products.php . I've used this one: http://www.4dsystems...prod.php?id=114 and I'm happy with it. It can be used with serial commands or programmed with 4D's 4dgl language. You can read about it, and see if it works for you. If you need help with it, I'd be glad to help.
