Pins of the NXJ

Postby Machiel » Fri Nov 28, 2008 9:11 am

From the NXJ output singnals, the connactor. Which pin is what?

I am building a sensor but I need to know what is what.

I thought the blue one was the SDA, the Yellow one the clock, the green and the black the GND and the red the VDD

Apparently this is uncorrect?

Could someone help me?
WHAAAAAAAA!

The Lego hardware doc gives the pin outs, but not the colours. But it should be easy to identify the two ground pins and the 4.3V line and work the rest out from that... I did this some time ago when modifying the code of the i2c driver so that I could hook up a scope to the pins... I'm not at home at the moment, but if you are still having problems let me know and I'll take a look when I get home....
