[Paparazzi-devel] Using Thermopiles for AHRS on Lisa/M instead of IMU

For reasons outside of my power (trying to dampen vibrations in tiny,
tiny aircraft leads to massive hair loss and frustration) I've got to
resort to using IR for the AHRS on our aircraft instead of Aspirin
v1.0. We're using Lisa/M and I was wondering: are there any default
assignments for which ports to use for thermopiles like with Tiny? The
wiki says there should be, but I have a feeling Lisa was designed
without thermopiles in mind since an IMU would work much better.

Also, why do analog gyros (more specifically Futaba Mini Piezo gyros)
work great for stabilizing the same plane with the same vibrations
that cripple the use of Aspirin v1.0 for AHRS?
