refactor: Move files

2010-06-16T00:27:32+00:00

Move all headers into include, separate source files into modules match, mtdev, src and driver, move some common definitions to common.h, and include define support for the MT slot protocol. This patch does not introduce any logical changes. Signed-off-by: Henrik Rydberg

Disable motion with resting thumbs

2010-05-13T23:41:39+00:00

Disable motion gestures whenever one of the pointing fingers is a thumb. Movement is skipped rather than held, minimizing unpredictable movement after thumb release. Signed-off-by: Henrik Rydberg

Refactor parsor memory usage

2010-05-13T23:41:39+00:00

Add the bitmasks "fingers" and "added" to parsor memory, and extend time handling to use a hold time and a forget time. Signed-off-by: Henrik Rydberg

janitor: Split gesture code into memory refresh and parse

2010-05-13T23:41:39+00:00

Split the gesture code into a lexical part, which updates the filtered motion state, and a parsing part, which translates the motion state to gestures. Signed-off-by: Henrik Rydberg

Simplify bit bookkeeping

2010-05-13T23:41:39+00:00

In preparation of adding several additional finger bit registers, remove the redundant bit-counting variables and introduce fast bit-traversal functions instead. Signed-off-by: Henrik Rydberg

Add memory debug convenience routines

2010-04-15T04:10:08+00:00

Output parsing memory values, switched off by default. Signed-off-by: Henrik Rydberg

Extract moving fingers

2010-04-15T04:10:08+00:00

The current code determines the moving, scrolling and swiping gestures based on the number of fingers on the trackpad, including the resting fingers at the bottom of the pad. With information about all fingers at hand, it is possible to determine which fingers on the trackpad are participating in a moving gesture. This patch computes the movement based on the pointing fingers only, and uses that number to determine the type of moving gesture. Signed-off-by: Henrik Rydberg

Extract pointing fingers

2010-04-15T04:10:08+00:00

Multi-finger clicks and taps are goverened by the number of pointing fingers on the trackpad. This number can be different from the actual number of fingers on the trackpad. For instance, a finger resting at the bottom of an integrated button, or a finger that accidentally touches the pad during a press, are not pointing fingers. This patch introduces extract_pointers(), which computes the number of pointing fingers on the trackpad, and uses that number to determine the logical button state.

Delay movement after a finger configuration change

2010-04-15T04:10:07+00:00

The current code responds to finger movement immediately after a finger has been placed on the trackpad, even if the touch is accidental. This patch delays the effect of the finger by 70 ms, resulting in fewer accidental movements. Signed-off-by: Arturo Castro Signed-off-by: Henrik Rydberg

Keep logical buttons separate from the hardware ones

2010-04-15T04:10:07+00:00

The button extraction currently modifies the MTState buttons, upsetting the semantics in a bad way. This patch adds the logical button state to the Memory structure, and uses it to compute the logical button change. Signed-off-by: Henrik Rydberg
