Release 0.9.5 "Everlasting" - Power management, offline graphics
This release brings two major new features: vastly reduced power drain, and off-line persistent graphics. New features ============ * Off-line graphics are the ability to draw images in memory instead of directly on screen. Like on HP calculators, this works by storing a graphic object in `PICT`. Unlike HP calculators, `PICT` is an actual variable in the current directory, meaning that you can have multiple `PICT`, although bitmaps use a lot of memory. For example, running `500 300 BLANK 'PICT' STO` will create a 500x300 pixels off-line image in `PICT`, and all graphic commands after that will draw in that off-line image instead of on screen. Off-line graphics are not immediately shown on screen, but are displayed before returning to the command line in a way similar to the `Show` command (i.e. centererd if smaller than the screen, and with scrolling if larger). They are also persistent, meaning that you need to explicitly `ClLCD` to erase them. * Add `Blank`, `BlankGrob`, `BlankBitmap` and `BlankPixmap` commands to create a blank image with default format, in HP GROB format, in DB48x bitmap (Black and white) format and in DB50x pixmap format (color RPL only). * Add `→HPGrob`, `→Bitmap`, `→Pixmap` commands which can be used to generate an HP-compatible GROB format, a bitmap or a pixmap (color RPL only) from an object. If the object is already a graphic, perform conversion. Note that on color RPL, conversions between color and monochrome formats are supported. Colors are converted to monochrome using grayscale patterns. * Add `→LCD` and `LCD→` commands to send an object to the current graphics, or to create a graphic object from the current screen content. * The `Off` command can now be used in a program and will preserve what is on screen. You can resume execution of the program by using the `ON` key. Add `PowerOffWithImage` command to show off-images even from programs. Bug fixes ========= * Fix display of object `Info` in the interactive stack * Clear system timers before entering system menu, so that the self test menu entry does not run a fast-paced loop. * Fix off-by-one error in result of `LastBitSet` (number bits starting at 0) * Correctly render color pixmaps when on the stack (color RPL only) Improvements ============ * Reduce power usage dramatically by disabling timers when going to sleep. This manifests as a higher battery voltage being shown, which is closer to what the DM42 firmware or integrated self-test would show. This will most likely improve battery life for interactive uses of DB48x. * Reorganize the `MemoryMenu` to make both GC and runtime statistics available * Reorganize the `GraphicsMenu` by topics to accomodate the new commands * Add image checks in the test infrastructure for RPL code examples * Add tests for RGB colors * Repair `make compare` which was trying to build a binary from `compare.cc` * Make `Sub` a compatibility spelling for `Extract`, not the default one * Adjust low battery indications to avoid premature warnings * Make `debug_printf` use lower-level routines that can run earlier after boot * Add `make INSTALL_PGM_ONLY=y install` option for faster install * Generate DB48x bitmaps by default instead of HP-compatible GROBs. Bitmaps use less memory when the width is not a multiple of 8. * Make test of pixel functions more reliable by increasing their timeout * Add help for `ModesMenu`, `SymbolicResults` and `NumericalResults` Signed-off-by: Christophe de Dinechin <[email protected]>

6+
off-line persistent graphics.

### New features
9+
10+
* Off-line graphics are the ability to draw images in memory instead of directly
11+
on screen. Like on HP calculators, this works by storing a graphic object in
12+
`PICT`. Unlike HP calculators, `PICT` is an actual variable in the current
13+
directory, meaning that you can have multiple `PICT`, although bitmaps use a
14+
lot of memory. For example, running `500 300 BLANK 'PICT' STO` will create a
15+
500x300 pixels off-line image in `PICT`, and all graphic commands after that
16+
will draw in that off-line image instead of on screen. Off-line graphics are
17+
not immediately shown on screen, but are displayed before returning to the
18+
command line in a way similar to the `Show` command (i.e. centererd if smaller
19+
than the screen, and with scrolling if larger). They are also persistent,
20+
meaning that you need to explicitly `ClLCD` to erase them.
21+
* Add `Blank`, `BlankGrob`, `BlankBitmap` and `BlankPixmap` commands to create a
22+
blank image with default format, in HP GROB format, in DB48x bitmap (Black and
23+
white) format and in DB50x pixmap format (color RPL only).
24+
* Add `→HPGrob`, `→Bitmap`, `→Pixmap` commands which can be used to generate an
25+
HP-compatible GROB format, a bitmap or a pixmap (color RPL only) from an
26+
object. If the object is already a graphic, perform conversion. Note that
27+
on color RPL, conversions between color and monochrome formats are supported.
28+
Colors are converted to monochrome using grayscale patterns.
29+
* Add `→LCD` and `LCD→` commands to send an object to the current graphics, or
30+
to create a graphic object from the current screen content.
31+
* The `Off` command can now be used in a program and will preserve what is on
32+
screen. You can resume execution of the program by using the `ON` key.
33+
Add `PowerOffWithImage` command to show off-images even from programs.
34+
35+
### Bug fixes
36+
37+
* Fix display of object `Info` in the interactive stack
38+
* Clear system timers before entering system menu, so that the self test menu
39+
entry does not run a fast-paced loop.
40+
* Fix off-by-one error in result of `LastBitSet` (number bits starting at 0)
41+
* Correctly render color pixmaps when on the stack (color RPL only)
42+
43+
### Improvements
44+
45+
* Reduce power usage dramatically by disabling timers when going to sleep.
46+
This manifests as a higher battery voltage being shown, which is closer to
47+
what the DM42 firmware or integrated self-test would show. This will most
48+
likely improve battery life for interactive uses of DB48x.
49+
* Reorganize the `MemoryMenu` to make both GC and runtime statistics available
50+
* Reorganize the `GraphicsMenu` by topics to accomodate the new commands
51+
* Add image checks in the test infrastructure for RPL code examples
52+
* Add tests for RGB colors
53+
* Repair `make compare` which was trying to build a binary from `compare.cc`
54+
* Make `Sub` a compatibility spelling for `Extract`, not the default one
55+
* Adjust low battery indications to avoid premature warnings
56+
* Make `debug_printf` use lower-level routines that can run earlier after boot
57+
* Add `make INSTALL_PGM_ONLY=y install` option for faster install
58+
* Generate DB48x bitmaps by default instead of HP-compatible GROBs. Bitmaps use
59+
less memory when the width is not a multiple of 8.
60+
* Make test of pixel functions more reliable by increasing their timeout
61+
* Add help for `ModesMenu`, `SymbolicResults` and `NumericalResults`
