Revisions of RA8875.cpp

Revision Date Message Actions
93:6fbc516de05e 2015-02-01 Corrected a PrintScreen problem where it was extracting the image memory "off by one" and then a color conversion error that nearly corrected for it. File  Diff  Annotate
92:ce1ab76e8614 2015-02-01 Focus on some performance optimization. Cache the width/height so it does not contact the chip for every need. File  Diff  Annotate
91:ca5f829e6d27 2015-01-28 Beginning to hook some additional performance metrics on the individual commands - see what is used most, evaluate optimization. File  Diff  Annotate
90:d113d71ae4f0 2015-01-28 persist screen width/height in the private data so that it does not have the burn the cycles to query the hardware on every need. File  Diff  Annotate
89:04575562c961 2015-01-25 Minor change to the text for return code lookup. File  Diff  Annotate
87:ee2240581aa7 2015-01-19 Added pixel api that uses point_t type. File  Diff  Annotate

85:022bba13c5c4 2015-01-13 Improved error checking on several methods. In general, if the relevant coordinates of an object are offscreen, it will return bad_parameter, rather than to draw it badly. File  Diff  Annotate

80:cc4fab58179c 2014-12-28 Forcing an update to get the documentation updated and published also. [Lately, the build process fails about 50% of the time, so too with creating documentation.] File  Diff  Annotate
79:544eb4964795 2014-12-28 cleaned up touch screen support, which included renaming the APIs to better reflect their purpose.; remove dead code, added documentation for methods that were missing it.; major refactor to the constructor, to move needed code to init(). File  Diff  Annotate
78:faf49c381591 2014-12-28 Continue work on touch screen, and some file refactoring for easier maintenance. File  Diff  Annotate
77:9206c13aa527 2014-12-26 Functioning touch panel updates - added method for calibration and a new API to get the touch in the "display" coordinate system. File  Diff  Annotate

63:ed787f5fcdc4 2014-03-23 Adding PNG support - which works for tiny png files but memory requirements may exclude it for larger images. File  Diff  Annotate
62:ba5d33438fda 2014-08-17 Fixed a bug in the pixel API which was visible when line( ) with same x,y coordinates for both points was used. File  Diff  Annotate

60:2dfd574f63bd 2014-08-16 Correct an issue - trap line(...) where the xy pairs actually represent a point, and call pixel(...) instead. It appeared that the RA8875 would hang in for this line api call. File  Diff  Annotate
59:fb40aad4efd4 2014-07-24 Nearly insignificant changes to the test code. File  Diff  Annotate
58:26658a56112a 2014-07-05 Change constructor init order to reduce compiler warnings.; Revise performance monitor #if wrappers so DEBUG is separate from performance monitoring. File  Diff  Annotate
56:7a85d226ad0d 2014-03-31 Updated documentation and an API parameter change in the layer handling - instead of "OnlyLayer1", "OnlyLayer2", it is now "ShowLayer0", "ShowLayer1", which is more consistent with other API parameters. File  Diff  Annotate
55:dfbabef7003e 2014-03-30 Cursor locate method corrected to use 8 pixels as the font width, not 16.; Renamed putp to _putp to suggest it is special.; Migrated _StartGraphicsStream, _putp, _EndGraphicsStream from private to public for faster pixel based screen updates. File  Diff  Annotate
