16 | * Many thanks to Oliver Kuechemann for his support. | |
17 | * | |
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. | |
05f091ab | 34 | * v1.2 - Reworked jitter timer as a kernel thread. |
1da177e4 LT |
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 | |
05f091ab DT |
52 | * "Tablet Manager". |
53 | * These three products are highly interactive with one another, | |
1da177e4 | 54 | * so therefore it's easier to document them all as one subsystem. |

401 | * aiptek_irq can receive one of six potential reports. | |
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 | |
093cf723 | 419 | * Proximity event occurred while the tablet was in absolute or relative |
1da177e4 | 420 | * mode. |
da9fda43 RP |
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. | |
1da177e4 LT |
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.) | |
