/v2_0/ChangeLog
0,0 → 1,55
2001-08-29 Kenichi Nakamura <nakamura@redhat.com> |
|
* cdl/touch_ipaq.cdl: Modified dependency on file I/O package. |
|
2001-04-24 Gary Thomas <gthomas@redhat.com> |
|
* cdl/touch_ipaq.cdl: Add dependency on file I/O package. |
|
2001-03-06 Gary Thomas <gthomas@redhat.com> |
|
* src/ipaq_ts.c: Fully interrupt driven mode, including select() |
support. Note: scaling for the touch screen is self calibrating. |
|
* cdl/touch_ipaq.cdl: Remove unused option for repeat interval. |
Repeat is automatic from the Atmel micro-controller. |
|
2001-03-05 Gary Thomas <gthomas@redhat.com> |
|
* src/ipaq_ts.c: |
* cdl/touch_ipaq.cdl: New file(s). iPAQ touch screen driver. |
