Samuel Rodríguez Pérez 3c60f80ae5 ps/2 elantech: v4 - Implement buttons, position, preliminary presure, fingers bitmap
v4 - Implement buttons

v4 - STATUS. Hardcode position to special (0,0) coordinates

This fixes mouse disapearing on first iteration and fixes scrolling a bit.
Provide tracing for coordinates provided on the cookie as STATUS packet
does not contain them.
Commented is assinged cookie position to (0,0) as this is used to restrict
MOTION positions in a visible way as workaround for its correct
implementation. This will be cleaned up later.

v4 - Add presure handling for HEAD and MOTION packets

Initial change to enable tapping on v4 devices.

v4 - Use fingers bitmap from STATUS on all packets

Provide fingers event with finger bitmap value from last STATUS packet
as neither HEAD nor MOTION packet provide that detailed information.

This change is essential to implement clickfinger behaviour, better
tapping conditions, two-finger scrolling, etc.

Haiku

Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs

Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

Goals

  • Sensible defaults with minimal configuration required.
  • Clean, clear, concise code.
  • Unified desktop environment.

Trying Haiku

Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.

Compiling Haiku

See ReadMe.Compiling.

Contributing

Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
