Hello all -
I want to start some experiments, to use the SX in RC modell avionics.

One of the possible sensors, I'm planing to use, is the HM55 compass module. Unfortunatly the resolution of 128 inrements is not fine enough for my project.

Is there a way to increase it to minimum 1 deg. or less????

Or has anybody any information about other compass chips, which could do that??? (I remember playing around with a chip from Phillips, I beleve, which was analog but cant find it anywhwere anymore)

I would not need an absolute value about north/south, just about the change of direction. (an accellerometer would NOT do the job, since the changes may happen very, very slow or very fast...)

 

Thanks, for any opinion,

EWo
