* The full block icon now has index 0 and the heart has index 7. This makes
the full block work if vBar custom chars are loaded (which use index 1-7).
* Prevent (hbar, vbar, bignum) modes from overwriting custom chars (except
full block).
* Prevent the heartbeat from overwriting custom chars in vbar and bignum mode.
* Make the driver point to 0x1A and 0x1B characters for right/left arrow
characters (those are the codes from HD44780 A02) and make all charmaps
pointing to the correct characters.
* It is now possible to map the tilde character.
* Update other drivers that use hd44780-charmap.h (IOWarrior and ula200).
* Replace characters using charmaps on input instead of output!
* Remove some unnecessary comments.
image writer is for debugging only. The Freetype font renderer still misses
some features (e.g. big numbers, character encoding, non-standard cell size).
backlight handling:
Previously if keypad=yes was configured in LCDd.conf a value for the
backlight was sent, regardless of the configuration in hd44780-serial.c.
Now it decides upon the backlight flag from that file (enabling it in
LCDd.conf is still required). If the backlight flag indicates the device
supports backlight, the backlight_on / backlight_off values are sent (even
if they are 0x00)!
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.
* Do not include system headers in shared files (stdlib.h).
* Don't include lcd.h only once in each driver.
* Remove some unnecessary headers from driver (e.g. syslog.h)
* Include <poll.h> instead of <sys/poll.h>
* Spelling fixes.
checking more than one header. It makes the driver appear several times in
the list of drivers to build. The driver will be built but fails to install
then (reported by D. Dumont). Use a nested way to check for headers instead.
but plays more nicely with the full block character used for ICON_BLOCK_FILLED.
Other changes:
- Use a full block with the last line cleared on 631/635.
- Remove unused icon definitions.
- Correct report level on some debug calls.
- Don't clear last line for big numbers.
- Remove the driver history - we have a SCM for this!
