Have you read the programming manual and the PhidgetSBC manual? They both cover this topic.

ok i did go to the InterfaceKit-simple.c file in line 134 quoted and then wrote
CPhidget_openRemote ((CPhidgetHandle)ifKit, -1,"http://phidgetsbc.local./", 0); where 0 i also put my password when i log in to http://phidgetsbc.local./(only the password) for example if my username:root
and my password:tragos
i put "tragos" instead of 0.
without any luck...can you help me?what am i doing wrong?

thank you for your time...

Try:

Code: Select all

CPhidget_openRemote ((CPhidgetHandle)ifKit, -1,"phidgetsbc", 0);

openRemote uses the serverID - this is not an http address. It's set on the webservice page in the SBC config website and defaults to "phidgetsbc".

ok thank you very much...but i have a second question for you...the textlcd i bought is connected via usb with the main sbc(1070). now i have the 1125 temperature/humidity sensor that gives me two cables one for everyone of the two sensors...if i connect the one to the 1070 sbc and the other to the textlcd 8/8/8 how can both be recognized???with the above function i open both interface kits? or for everyone i must call another function???aqnd if yes with what argument for textlcd 8/8/8???

thank you again...

You'll need to open the two separate interfacekits. You'll probably want to specify the serial number in the open command so you can tell them apart.

thank you, you were quite helpful so i managed to do that. But i tried to connect to the 1070SBC and take measures from my Temperature sensor. I used the interfacekit-simle.c and put into it the temperaturesensor-simple.c as it follows:

i think that the problem is in the blue font line, but i don't know what to put as argument...the interface kit is being attached successfuly, but the the temperature sensor isn't attached...

What should i do to make it work???

i don't know why the font color kai underlying isn't working...Anyway i mean the
CPhidget_openRemote ((CPhidgetHandle)temp, -1,"phidgetsbc", 0);

command in the int tempsensor_simple() function.

Now patrick I want to ask you a second question...I have a project to make, and if i catch up within the deadline i want to write code in C, matlab, Java and perhaps (Labview otherwise Matlab with Simulink)...So i tried to run the matlab example analogin.m and it seems that there is a problem with VS2008 libraries i get the error:

??? Error using ==> loadlibrary at 365
Failed to preprocess the input file.
Output from preprocessor is:'cl' is not recognized as an internal or external command,
operable program or batch file.

Error in ==> analogin at 4
loadlibrary phidget21 phidget21Matlab.h ;

i searched in mathworks and says about the path variables of VS2008. i set them manually but doesn't recognize them yet...i did write the paths to environment variables in win7 (i have 64-bit) and to the matlab command line using (!) so as to understand windows command line, but none luck...what should i do to solve this and go on???

And lastly only these 3 examples there are for matlab???nothing else???

thank you very much for your time!!!

The temperature sensor that you are using (the 1125) is simply an analog sensor. You cannot "connect" to it using the Open commands.

You need to access the port (index) of the InterfaceKit that you plugged the sensor into.

Code: Select all

int CPhidgetInterfaceKit_getSensorValue (CPhidgetInterfaceKitHandle phid, int index, int *sensorValue)


Then use the formula in the 1125 manual to convert the sensorValue into a temperature.

thank you erik, i'll try that and i'll get back to you...

now does anyone know how to solve the problem with matlab??
see my previous post...
