New PhidgetSBC Firmware Version 1.0.4

[Patrick]

Have you installed the 64-bit Visual studio compiler/libraries? These are not installed by default, so you'll have to select them specifically in the installer. If you are using the Express version of Visual Studio (the free version), then it doesn't support 64-bit compiling, but you can install the 64-bit compiler by installing the Windows SDK, which can be downloaded for free.

As for better Matlab support - we are definitely planning this. We hope to provide a more integrated solution, rather then just calling directly into the C library. Right now, Matlab support is more of a 'proof of concept' with some examples, then a fully supported language (with examples for every Phidget).

Thank you for your quick response...
i have installed VS2008 professional edition that supports both 32-bit and 64-bit sytems...so what do i have to do now, to install also windows SDK????

And as far it concerns matlab's support, when we should be expecting it???

[Patrick]

Have you explicitly selected the 64-bit C compiler in the Visual Studio installer?

No date on full Matlab support. It's a big project, and not yet started.

i did reinstall the VS2008 with x64 compilers/libraries components, but now i get another error:

[Patrick]

That's odd, what version of Matlab are you using?

You can just delete the offending lines and try to continue. (lines 700-701 from phidget21matlab.h).

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.

Hello again...Itried the function above but i am a little bit confused...Somewhere i must declare the CPhidgetInterfaceKitHandle phid of the function so as for the program to know where it should be searching...I'm sending the code:

// - TemperatureSensor simple -
// This simple example simple opens a temperature sensor phidget and waits for one to be attached.  The program will then wait for
// user input to terminate.  While waiting it will display the data generated by the events, such as the temperature change event
// which will display the currently measured temperature without sensitivity modifications.

// - InterfaceKit simple -
// This simple example simply creates an InterfaceKit handle, hooks the event handlers and opens it.  It then waits
// for an InterfaceKit to be attached and waits for events to be fired. We progress through three steps, 1. Normal settings, 
// 2. Setting analog sensor sensitivity to 100, 3. Toggling Ratiometric, waiting for user input to proceed to next step to allow 
// data to be read.

can you tell me what should i do to make it work??what should i declare as CPhidgetInterfaceKitHandle phid because i put ifkit and correctly it says that is not defined, such it is below in the next function int interfacekit_simple()...

[erik]

In interfacekit_simple() on the line where you have

Code: Select all

tempsensor_simple(&tempsensorValue);

replace with

Code: Select all

CPhidgetInterfaceKit_getSensorValue ((CPhidgetInterfaceKitHandle)ifkit, 0, tempsensorValue);

If you are using the 1125 Temperature/Humidity Sensor (http://www.phidgets.com/products.php?ca ... ct_id=1125), then you cannot use any of the code from TemperatureSensor-Simple.
TemperatureSensor-Simple is only used for 1051 PhidgetTemperatureSensor 1-Input (http://www.phidgets.com/products.php?ca ... ct_id=1051).

a is that so??ok then.
and for my 1125 sensor what must i do???is any project to see how the program must be built???

[AdamS]

You would need to use a code sample for the PhidgetInterfaceKit. There should be a InterfaceKit-simple program in there, and to get the data for the temperature sensor you would need to poll the sensor value of the index in which the temperature sensor is plugged in, or use the sensor changed events.
