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.
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.
DELAY_IOCALLS is configured. DELAY_IOCALLS is never selected automatically
but has to be configured by the user anyway. Did not use writes to 0x80 as
readings make me think this tries to delay by 1ms where we want 1us.
- Remove instructions that have been transfered to the User's Guide.
- Remove the unused line drawing function.
- Pass through indent.
- Add more comments to the initialization code.
- In the user guide remove table with wiring scheme by LCD pin but add a new
one for bitshaker wiring.
* Add Doxygen comments (also for internal functions, shortened for API).
* Document initialization.
* Remove some unused variables and defines.
* Pass through indent.
* Remove references to LCD pins from documentation and add some warning.
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'.
* Add more documentation about the inner working of this driver.
* Consolidate constant definitions.
* Stop the 'include-mania': Only include necessary header files within the .c
files.
* Use lpt-port.h to define LPT port register values.
* Modify some comments to conform the the style guide.
