Hi George

I agree with gain... Reading the datasheet seems to be way to go ... If it over saturates you get the -4096 figure.

I also am assuming that X is north... Certainly shows like that at in most of places I have looked.

Y seems to be either West (left) or East (right).... depending on what you look at... I did find a useful Honeywell document yesterday, will post a little later on.

There is certainly a shortage of info around as to how to use these devices with PicBasic
