Decide between:

• Call when total affinity drops below minimum.
• Call when affinity/frames in template drops below the minimum.

Requirements:

• Write tests.
• accel_find_most_likely_gesture can be called at almost any time.
• Typedef the function as having the name accel_callback_found.
• accel_generate_state should take an additional nullable parameter of accel_callback_found.
• A NULL accel_callback_found implies the user will call the accel_find_most_likely_gesture method themselves.
• Setup ACCEL_MIN_RESERVED.

The callback's signature is as follows:

int accel_callback(accel_state* state, const int gesture_id, int affinity, bool *reset_gesture);

We guarantee that:

• Neither pointer passed to accel_callback will be null.
• The gesture_id is the gesture that has been triggered.
• Setting the reset_gesture to be true will result in the gesture being reset after the callback is triggered, and setting it to false will allow the gesture to not be reset. (No default value is promised.)
• The value returned, if not ACCEL_SUCCESS will cause the calling method to abort and return the same value. It is cautioned that ACCEL_* values are reserved to be in the range of [0, ACCEL_MIN_RESERVED]. Custom error messages should be outside this scope to be differentiable from accel errors.

It should be simple implementation:

• Extract lines 295-300 from accel_end_record_gesture in accel.c to a method
• Write tests.

The method signature should be as follows:

int accel_reset_affinities_for_gesture(accel_state *state, int gesture_id);

• Returns standard success/failure values in the accel.c stuff.
• First argument must not be NULL.
• Second argument must be a valid index of a recorded gesture.

QUESTION:
I zipped the files located at https://github.com/shalecraig/accel/tree/master/sample/simple-accelerometer and imported the zip on CloudPebble.
Upon building I get an error though...
It seems the file accel_consts.c is missing from your project.
Is it possible to add it please?

In file included from ../src/accel.c:25:0:
../src/accel.h:6:26: fatal error: accel_consts.c: No such file or directory
compilation terminated.

RESPONSE / SOLUTION (I can confirm that this fixes the issue!):
If you look at the commit where I deleted them[0], we I deleted
accel_headers.c, since it wasn't used anymore, and forgot to update
the example.

Try overwriting the source files in[1] with the ones in the root of
the project[2].

• accel should be able to handle data for 1 second segments.
• accel should still be able to handle individual ticks
• the callback defined in #28 should be called as affinities are rolled-over, and respect for the callback's response for clearing data.
