| 18 | * ChangeLog: |
| 19 | * v0.1 - Initial release |
| 20 | * v0.2 - Hack to get around fake event 28's. (Bryan W. Headley) |
| 21 | * v0.3 - Make URB dynamic (Bryan W. Headley, Jun-8-2002) |
| 22 | * Released to Linux 2.4.19 and 2.5.x |
| 23 | * v0.4 - Rewrote substantial portions of the code to deal with |
| 24 | * corrected control sequences, timing, dynamic configuration, |
| 25 | * support of 6000U - 12000U, procfs, and macro key support |
| 26 | * (Jan-1-2003 - Feb-5-2003, Bryan W. Headley) |
| 27 | * v1.0 - Added support for diagnostic messages, count of messages |
| 28 | * received from URB - Mar-8-2003, Bryan W. Headley |
| 29 | * v1.1 - added support for tablet resolution, changed DV and proximity |
| 30 | * some corrections - Jun-22-2003, martin schneebacher |
| 31 | * - Added support for the sysfs interface, deprecating the |
| 32 | * procfs interface for 2.5.x kernel. Also added support for |
| 33 | * Wheel command. Bryan W. Headley July-15-2003. |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 34 | * v1.2 - Reworked jitter timer as a kernel thread. |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 35 | * Bryan W. Headley November-28-2003/Jan-10-2004. |
| 36 | * v1.3 - Repaired issue of kernel thread going nuts on single-processor |
| 37 | * machines, introduced programmableDelay as a command line |
| 38 | * parameter. Feb 7 2004, Bryan W. Headley. |
| 39 | * v1.4 - Re-wire jitter so it does not require a thread. Courtesy of |
| 40 | * Rene van Paassen. Added reporting of physical pointer device |
| 41 | * (e.g., stylus, mouse in reports 2, 3, 4, 5. We don't know |
| 42 | * for reports 1, 6.) |
| 43 | * what physical device reports for reports 1, 6.) Also enabled |
| 44 | * MOUSE and LENS tool button modes. Renamed "rubber" to "eraser". |
| 45 | * Feb 20, 2004, Bryan W. Headley. |
| 46 | * v1.5 - Added previousJitterable, so we don't do jitter delay when the |
| 47 | * user is holding a button down for periods of time. |
| 48 | * |
| 49 | * NOTE: |
| 50 | * This kernel driver is augmented by the "Aiptek" XFree86 input |
| 51 | * driver for your X server, as well as the Gaiptek GUI Front-end |
Dmitry Torokhov | 05f091ab | 2005-05-29 02:29:01 -0500 | [diff] [blame] | 52 | * "Tablet Manager". |
| 53 | * These three products are highly interactive with one another, |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 54 | * so therefore it's easier to document them all as one subsystem. |

| 402 | * The documentation for each is in the body of the function. |
| 403 | * |
| 404 | * The tablet reports on several attributes per invocation of |
| 405 | * aiptek_irq. Because the Linux Input Event system allows the |
| 406 | * transmission of ONE attribute per input_report_xxx() call, |
| 407 | * collation has to be done on the other end to reconstitute |
| 408 | * a complete tablet report. Further, the number of Input Event reports |
| 409 | * submitted varies, depending on what USB report type, and circumstance. |
| 410 | * To deal with this, EV_MSC is used to indicate an 'end-of-report' |
| 411 | * message. This has been an undocumented convention understood by the kernel |
| 412 | * tablet driver and clients such as gpm and XFree86's tablet drivers. |
| 413 | * |
| 414 | * Of the information received from the tablet, the one piece I |
| 415 | * cannot transmit is the proximity bit (without resorting to an EV_MSC |
| 416 | * convention above.) I therefore have taken over REL_MISC and ABS_MISC |
| 417 | * (for relative and absolute reports, respectively) for communicating |
| 418 | * Proximity. Why two events? I thought it interesting to know if the |
Steven Cole | 093cf72 | 2005-05-03 19:07:24 -0600 | [diff] [blame] | 419 | * Proximity event occurred while the tablet was in absolute or relative |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 420 | * mode. |
Rene van Paassen | da9fda4 | 2007-05-21 00:32:03 -0400 | [diff] [blame] | 421 | * Update: REL_MISC proved not to be such a good idea. With REL_MISC you |
| 422 | * get an event transmitted each time. ABS_MISC works better, since it |
| 423 | * can be set and re-set. Thus, only using ABS_MISC from now on. |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 424 | * |
| 425 | * Other tablets use the notion of a certain minimum stylus pressure |
| 426 | * to infer proximity. While that could have been done, that is yet |
| 427 | * another 'by convention' behavior, the documentation for which |
| 428 | * would be spread between two (or more) pieces of software. |
| 429 | * |
| 430 | * EV_MSC usage was terminated for this purpose in Linux 2.5.x, and |
| 431 | * replaced with the input_sync() method (which emits EV_SYN.) |
