Fix heartbeat and bignum by mapping character 0 to 8.
Fix backlight and contrast handling (by M. T. Jones).
Add more icons (by M. T. Jones).
Add OffBrightness for 20x4 (idea by S. Crane).
Add range checking for config settings.
- Limit the maximum size to 40x16 (240x128 pixel) and change the RAM locations
to make use of 8 KB only. (If one's display is larger and has more memory this
may have to be changed.)
- Drive control lines using defines from lpt-port.h without using a function.
- Use timing.h for delays (which are now optional).
- Remove any use of the graphic area and mode settings, except for optionally
clearing of graphic memory on start-up.
- Remove any cursor related stuff.
- Handle displays correctly which width (in pixels) is not a multiple of the
cellwidth (e.g. 128x64).
- Remove double buffering (display updates are already really fast).
- Update text and font memory using AUTO WRITE function.
- Remove the bignum stub. Now at least something is displayed.
- Fix character offset for bar graphs.
- Make local functions static and inline the most commonly used read / write
functions.
- Add a structure describing known models, their features and default settings.
- Use partial screen updates for newer CFA633 versions.
- For CFA533/633 use the same character mapping as for HD44780.
- Fixed a few typos.
- Use C-style comments only.
- Add a warning about the driver being deprecated to CFontz633. Users should
use CFontzPacket with Model=633 instead.
- 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)
