- 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.
- Add 68-familiy style interface support and make it configurable.
- Make delay configurable.
- Correct swapped display halves.
- Resurrect vBar / hBar functions.
- Fix icon definitions and modify set_char for common data format.
- Cache status of LEDs and only send on update, reduces communication
- Add prototypes for all and Doxygen comments to internal functions
- remove unused read_ACK()
strings err1 and err2 off-screen to (30,5). In LCDd, render_string
moved the string to (width,5). On displays with less than 5 line the dot
was not drawn, but on those with 5 or more lines. Moving the start of string
to (0,0) makes render_string ignoring it completely.
- 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.
hBar width). Use block charcter (31d) on displays which have it instead of
the custom icon. On seamless displays do not fill the last line to avoid the
character banging together.
compiled and used with recent Windows systems (Windows Vista/7). Except for
serial drivers (and those using USB->serial adapters) drivers are not expected
to work with those systems.
- 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.
a sequence of characters or commands have to be terminated (common_init,
position, flush). Modify the lcd2usb subdriver to implement a small command
buffer and implement flush().
in the 4bit and 8bit wiring. This fixes problems with flickering backlight if
a slow parallel port is used. IMPORTANT: This may require a hardware change!
* In code comments use the same line names as in the user's guide (Y1/X1
instead of Y0/X0).
* Add documentation about hd44780-ftdi's 4bit mode.
working getopt implementation (we don't use getopt_long at all).
Include {topdir}/shared for the clients so they pull in our included
getopt.h. This fixes bulding on systems which have getopt(), but no getopt.h.
