Adam M Rivera ca82350f17 AP_Declination_test: Updated test with better print messages.
13 years ago
Adam M Rivera 01b1e58f7d AP_Declination: Update LUT based on the changes that I made in the LUT generation code. This LUT is the final version that has no truncation.
13 years ago
Adam M Rivera 23f6093f05 AP_Declination: Updated comments to reflect new LUT size.
13 years ago
Adam M Rivera 50791a8b0f AP_Declination: Removed trailing zero deltas as they have no impact on the final value and only take up extra bytes.
13 years ago
Adam M Rivera f35e447927 AP_Declination: Updated compressed lookup value table. Located 9 more failure points due to truncation on the packed LUT.
13 years ago
Adam M Rivera 72b70c394c AP_Declination: Found 7 of the 22 failure points and fixed them. The issue with those 7 was the way I originally packed the value array. The last delta values on some rows were getting truncated. The new number of failures is down to 15 - WIP.
13 years ago
Adam M Rivera 076192db51 AP_Declination: Updated test to run in 5 degree increments. Changed to only print failures and also print total pass vs total fail.
13 years ago
Adam M Rivera 230ca1ddca AP_Declination: Moved check for y index of zero to after the y index is properly transformed.
13 years ago
Adam M Rivera e0fa053c79 AP_Declination: The exception signs unpacking logic was incorrect. I was shifting a 1 value left y%8 which would have needed a the signs to be packed right to left. My packed signs byte was packed left to right (left most being the 0 position) so I needed to reverse the shifting.

Adam M Rivera f66c6e16e4 AP_Declination: In order for the bitwise & operation to work, negative signs need to be represented by 1s instead of 0s. Changed so that negative signs are represented by a 1 in the packed signs array. Updated lookup logic to reflect this change.
13 years ago
Adam M Rivera d88b9e8ffc AP_Declination: Updated packed exception signs array. I had the signs packed incorrectly.
13 years ago
Adam M Rivera 036da88174 AP_Declination: Changed test to run in increments of 10 degrees. 1 was too granular.
13 years ago
Adam M Rivera 580b274bde AP_Declination: Added original array to test sketch. Added loop to validate new compressed array against original in 1 degree steps.
13 years ago
Adam M Rivera efefc3e4f4 AP_Declination: Moved rows with large spikes in delta to their own unsigned exception rows. The signs are in a separate packed array.
13 years ago
Adam M Rivera 0dcc4e8307 AP_Declination: Implemented Delta Encoding and Run-Length Encoding. Added method to traverse the compressed array and return the lookup value based on the same lat_index/lon_index that was used before.

Adam M Rivera 3a849771bc AP_Declination: Changed PROGMEM read function to pgm_read_word_far to support the int16_t datatype.
13 years ago
Adam M Rivera 370e56c00a AP_Declination: Changed datatype to int16_t to support the -90 <-> 90 latitude range.
13 years ago
Adam M Rivera ae257ad42b AP_Declination: Reduced the size of the lookup table to support -75 <-> 70 latitude range. This allows the datatype to remain int8_t.

Adam M Rivera d2a07b1603 Added AP_Declination library. It contains the lookup table (lat/lng -> declination) as well as a method that performs the lookup.
