Re: NXC: how to calibrate the HT Compass sensor?

Glad that helped. Now I'm curious how much the error I was seeing was due to being inside my house too? I'll have to play a bit more with it this weekend. When inside, maybe you could use a "compass" like this! hOB_kH610oI (I thought you might like this after reading some of your posts abo...

Problem was, I needed to control 3 functions (left/right, up/down, and fire), but my Lego remote (8885) only has 2 functions per each of it's 4 channels....
