Tilt problem

tfiegenb

The tilt function http://learn.parallax.com/propeller-c-simple-devices/tilt-and-acceleration-mx2125isn’t working. When running the program as described at the above link I get “ tilt x -90, tilt y = -90,” It doesn’t make any difference if I tilt theboard, I get a constant and unchanging readout.
I am wondering if the module is defective or if it is the correct module. It looks like the one from the Parallax web site http://www.parallax.com/product/28017 however, the part numbers do not match.
The curriculum calls for a MX2125. The device I have which looks the same isST-00008.

Upon further research it appears the ST-00008 is wrong part though it looks the same. There is a Memsic 2-axis- accelerometer and a 4 Directional Tilt sensor. I have the 4 directional Tilt Sensor.

I don't think there is any C code for the tilt sensor, but the product page:

http://www.parallax.com/product/28036

has SPIN and BS2 code that should be easy to translate.

There's a big difference in the output from the sensors. The tilt sensor is just on or off for a particular direction of tilt. It doesn't give you any sort of angle information. I think it's kind of like having four buttons. Which "button" or direction is "on" depends on which way it's tilted.

tfiegenb, there is a C project with the 4-Directional Tilt Sensor. It uses the simpletools.h get_states function.
