1  Using Arduino / Motors, Mechanics, and Power / Re: Read 220v relay status (in order to know if someone switched on the light) on: March 27, 2014, 02:30:27 pm
Have you checked if the latching relays are dual pole ?
I have those in my place and use the second pole to read the contact status with a 5V signal.
2  Using Arduino / Project Guidance / Re: Simple question on if else statement on: March 25, 2014, 06:32:47 am
if (i = 'm')  will give the value m to i, it will not compare i with m.


Comparison Operator

 x == y (x is equal to y)

else if (i == 'm')
3  Using Arduino / General Electronics / Re: Relay Board on eBay with 8 Relays on: March 21, 2014, 04:35:47 pm
The board I use does not have optocouplers, only transistors to keep the arduino output current low.
Optocouplers were not required for my application

I use this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=310735757385 one with a MEGA and it works fine

I'm surprised to see different results. It's mac versus linux and IDE 1.0.5 versus IDE 1.0.1.
Don't know if there's much more we can do for the moment to help the  OP.

Can you confirm that you own the display and that the sketch not only compiles without errors but that the display also works?
I don't have that display, I have 2 other that work well with UTFT.

OK, it compiles without errors on my mac.
What I did is :
- I downloaded the sketch at the Japanese link mentioned above
- I downloded the UTFT library at the same Japanese link
- I downloaded IDE 1.0.5
- I installed the downloaded UTFT library
- I opened the sketch downloaded at the Japanese link with IDE 1.0.5
 The sketch compiles without error without any further editing.

NOTE: I have many other versions of  the IDE on my mac with the UTFT library downloaded, directly from http://www.henningkarlsen.com/electronics/library.php?id=51
When compiling with these versions, I get the same error as you.

My advice is to make sure you use IDE 1.0.5 and the sketch and library from the Japanese site.
Reinstall the IDE and library and try again, it should work.

The screendump below is in Dutch but it says compiling has completed without errors.

Tonight I will download the sketch and the library from the links on the page where you bought the LCD and I will try to compile it.

can you see the UTFT library examples in the IDE, this would confirm that you installed the libraries correctly.
10  Using Arduino / Displays / Re: CTE35 was not declared in this typel on: March 17, 2014, 06:57:58 am
Did you download and install the UTFT library ?
11  Products / Arduino Due / Re: Easytranfer between Due and Mega PROBLEM SOLVED !!! on: March 02, 2014, 05:17:49 pm
Ahh,just remembered i posted this a bit back, this should clear it up. The library doesn't work as it is it need editing. Here is my post on it from last year. hope it works for you. I'm using version 1.7

http://forum.arduino.cc/index.php?topic=144679.msg1086585#msg1086585
It works !!!
Thanks for sorting this out, this will make a huge speed difference for my project as I will be able to use the DUE for my TFT.
I can now use EASYTRANSFER between the MEGA and the DUE in both directions (only with floats but I can live with that)
THIS IS GREAT !!!
Thank you so much.


12  Products / Arduino Due / Re: Easytranfer between Due and Mega on: February 27, 2014, 05:11:28 pm
I tried again but without success, the DUE won't receive anything.
Could you give me the stucture of a working sketch ?

I use this but it doesn't work

Code:
struct SEND_DATA_STRUCTURE{
  //put your variable definitions here for the data you want to receive
  //THIS MUST BE EXACTLY THE SAME ON THE OTHER ARDUINO
  float temp1;
  float temp2;
};

I gave up the idea to use a DUE but now reading this i will give another try.
Thanks !
14  Products / Arduino Yún / Re: No access to web portal interface on: February 14, 2014, 06:51:23 am
can you ping the adresses ?
it is not because they appear on screen that you can ping them, ping them to be sure they were given by your router
15  Products / Arduino Yún / Re: Is it possible to setup Yun in a fixed IP's network? on: February 14, 2014, 06:48:16 am
You will need to get an IP address and gateway from you network administrator to set up your Yun.
I have a yun running on my home  network and it has a fixed IP address,  but that does not mean it will work on your school network, depends on the settings made by the network administrator

at the office, only registered PC's can connect to the network, a PC that is not registered cannot connect
