ワ Wa

Wacom strokes through evdev over userland realtime tablet controller device for programs or systems

Install

(LOAD "wa.lisp") (WA::SET-DEVICE "/dev/input/by-id/usb-WACOM_CTE-440-U_V4.0-3-mouse") (WA::WA) (WA::COMPILE-WA-IMAGE)

• keyboardless environment concept
• accessibility driver for keyboard-impaired
• Lisp access over a Wacom or touch tablet

ワコムタブレット evdevシステム

To calibrate a new device bytestream, connect the device, check for the new device in /dev/input/, and use the evdev tool evemu-record while using the physical device to review hardware event information and register the appropriate event functionality in wa.lisp.

• working with evdev tools
• kernel doc on hardware input event codes
• kernel input source (input event structs)

currently supported devices:

• build tested on Wacom CTE-440
• most touch or graphic tablets

thanks to jtgans for cl-evdev, the fork with wacom support added is here

To Do

• fullscreen
• scaling compensation
• stroke smoothing / better signal processing
• lisp repl entry bootstrap
• -> save to image
• -> isolate "minimalist" sexps
• -> (signal processing parametric structs?)
• -> strokes to edit function entry macros
• -> view / navigate lisp image
• userspace binds
• gl primitive compression / optm
• large scale + sector update
• fluid computation
• CA material reaction, water/dye deposition
