The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.
Nxt compass sensor tutorial.
The essentials are things every nxt programmer should know.
This tutorial for lego mindstorms nxt is divided in two sections.
But if you are using a port splitter or a remote nxt or rcx it may be of interest.
Using hitech compass sensor.
I think this is a limit of the nxt g interface not the sensor itself.
The current heading is calculated to the nearest 1 and refreshed 100 times per second.
Put a compass equiped ro bot on a turntable and spin the turntable.
If you are using a sensor connected directly to a nxt sensor port you can use the sensorport class and you can probably skip this section.
It implements the same methods but uses a compass sensor to ensure that the pilot does not deviate from the correct angle of robot heading.
The current heading is calculated to the nearest 1 and refreshed 100 times per second.
Using nxt components with a micro controller.
Program using labview lego.
However rather than just providing schematics and sample code for the bs2 i ll be providing some theory on how the sensors work as well.
The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.
The compass sensor is housed in a standard mindstorms sensor housing to match the other mindstorms elements.
The nxt compass sensor contains a digital magnetic compass that measures the earth s magnetic field and calculates a heading angle.

Some of these movies have exercises directly under them.
A brief introduction tutorial part 2 duration.
Since the us sensor block returns only a single byte the sensor returns the heading angle divided by two currently.
It needs a hitechnic or mindsensors compass sensor plugged in to one of the sensor ports.
At brickfest there was a wonderful demo of the compass sensors.
This is a guide to using the motors and sensors from the lego nxt set with a parallax basic stamp ii or bs2.
