hi,

I'm looking at getting some vernier sensors but I'm not shure If LeJOS will work with them do they?
Thanks!

I don't think anyone has tried them. I assume the NXT Sensor adapter that is needed, is driven by I2C. A Java class would need to be written for the adapter, and possibly for each sensor. The current I2C restrictions mike cause us problems.

hi

thats great do you think you coulddo that beacuse that would make a ton of new sensors avabile.
Thanks!

Hi Nat,

Just to expand on what Lawrie said, if these are I2C sensors you are talking about you would need to extend the I2C class and add some code to get the readings you are after. It's very simple to do, and you can see some examples in our UltrasonicSensor and ColorSensor code.

Right now we don't have a facility in leJOS NXJ to write to I2C sensors (we can just read data). Soon we should have read ability too, then it will open up the functionality of some more sensors.
