I'm trying to extract nav data from a hex dump. I've captured it according to this manual: http://blog.perquin.com/blog/ar-drone-navboard/.
To extract data I follow steps: convert hex -> byte.
Results are a bit confusing. What I'm doing wrong?
This is an example of captured data package:
ax = 2a ay = 00 az = 3c
After conversion both hex digits at once:
ax = 42 ay = 0 az = 60
After conversion hex digits separate.
ax = 5097 ay = 4848 az = 5199
ax = (ax - ax_offset) / ax_gain.
