Detecting sensor type

[Forceflow]

As I've read in several other threads, there is no way of detecting which sensor is attached to which port with the standard API methods.

Would the following approach work ? (I am aware of the utter dumbness of it, but still)

new TouchSensor(SensorPort.S1)
new TouchSensor(SensorPort.S2)
new TouchSensor(SensorPort.S3)
new TouchSensor(SensorPort.S4)

And then do some kind of check or value read, and see where it works, and eliminate where it fails ?

The problem is: NXT brick = limited memory and no garbage collection. Oh joy

My apologies if this is a very stupid question, we've just started out experimenting with Lejos

I don't think there is a software solution to the problem of incorrect connection of sensors to ports. I color-code my wires at the ends to make the eye ball solution more reliable.
If you think the NXT memory is limited, try programming the RCX. You can program to minimize memory leaks by never letting the keyword new appear in a method, only in the constructor. And remember that
LCD.drawString("hello world",0,0) creates a new string.

Hi Forceflow,

If you are using I2C sensors you can use some methods in the I2CSensor class to query the sensor type:

getProductId()
getSensorType()
getVersion()

You are right about the lack of garbage collection - tread carefully when you are programming and it shouldn't be much of a factor.

I have no idea how you could troll for different analog sensors.
