In the documentation replace the list of the connection types for hd44780
driver with the table also used in the configuration options description
(use only a single place to list and link everyting). While there, remove the
assembly code for lcdserializer.
1. Remove connection type header files and put prototypes locally and in
glcd-drivers.h. Don't fall into the pitfall of too many header files again.
2. Create a separate frame buffer structure (this allows easier re-use of
the frame buffer functions).
3. Add a function to retrieve pixel values from framebuffer.
4. Add the 'serdisplib' connection type.
5. Support display width that are not a multiple of 8 (e.g. 122x32).
image writer is for debugging only. The Freetype font renderer still misses
some features (e.g. big numbers, character encoding, non-standard cell size).
the original font of the HD44780 with European character set, but includes
only characters from ISO 8859-1 and has been extended with bar graph and icons.
The t6963 driver now has its size to be configured in pixels! The size in
characters is automatically calculated based on the cell size. This makes
internal calculations more easy.
- Convert set_char to 8 byte bitmap.
- Reset ccmode on clear. Add a custom character cache to avoid unnecessary
updates of custom characters because of the reset.
- Add support for bignum.
- Remove the FB_modified flag, it did never work. Instead add a backing store
buffer to compare against. Remove the 40ms block of updates, this was a
no-op as well. However, pause 40ms after sending a complete screen update.
The display I have requires this to recognize the following cursor updates.
- Do not treat frame buffer as string. Always use memcpy, memcmp, and memset.
- Remove the changelog. This should be read from SCM.
- Remove contact info as T. Riewe has left Pyramid.
- Pass through indent, preserving 4 space indention.
CVS and was not to be compiled by 'make'. However, it may serve as a template
for new drivers. Therefore add it to Makefile.am to have it in the
distribution. Note that it will only get compiled if explicitly given to
configure or if '--enable-debug' is used with '--drivers=all'.
- Fixed vbar & hbar - Allowed for displays with 2 custom characters
- Fixed cursor off - 16H - Data sheet for CU20045SCPB has error -> Cursor Off 14,16,17H
- Tested with CU40026SCPB-T20A - 40x2 - Hardware Defaults to 19200 8E1
- Added new config parameter [Parity] to set serial data parity 0(none),1(odd),2(even)
- Added config parameter OffBrightness
- added support for big numbers
