The following driver files only contain initialization and configuration fuctions and were erroneously set up for speed-optimization. Moving them to size-optimization saves significant space. They all share common runtime functions contained in `drivers/accgyro/accgyro_mpu.c` which is correctly speed-optimized.
```
drivers/accgyro/accgyro_mpu6050.c
drivers/accgyro/accgyro_mpu6500.c
drivers/accgyro/accgyro_spi_mpu6000.c
drivers/accgyro/accgyro_spi_mpu6500.c
drivers/accgyro/accgyro_spi_mpu9250.c
drivers/accgyro/accgyro_spi_icm20689.c
```
Also added explicit `#ifdef USE_` around the code of some of the drivers missing it. Doesn't result in any space savings as the compiler optimizes out the unused functions. But better in the long-term as it will flag any cases where the code might be called without proper bounding.
Saves 10704 bytes on STM32F7X2.
- Add displayWriteFontCharacter() for font writing, removing all max7456
specific code.
- Add displayIsReady() for asynchronous display initialization
- Add displayBeginTransaction()/displayCommitTransaction() for display
transactions, which allow performing complex drawing operations without
flickering
- Add displayGetCanvas(), which retrieves the canvas associated with a
display (if it has it)
- Add canvas implementation for pixel based access for a display
- Add FrSkyOSD driver and displayPort driver
- Enable FrSkyOSD driver for targets with flash > 256
- Rename max7456_symbols.h to osd_symbols.h
Instead of having individual menus for RTC6705, SmartAudio, and Tramp, Now there is a single VTX menu that detects the type of active device and redirects to the appropriate protocol menu.
Reduces confusion and chances of erroneously using the wrong VTX menu.
Fixes a problem where the Tramp menu could be used to change band/channel/power even though the VTX was a SmartAudio device.
If the VTX is not configured or not communicating, a more informative message will be presented rather than a partially populated protocol menu. For example:
```
VTX NOT RESPONDING
OR NOT CONFIGURED
> BACK
```
Extends the CMS menu capabilities by adding an optional `redirectCheck` function that can conditionally return a menu that should be redirected to instead of the current menu. This redirect happens before any processing happens for the original menu. Adds flexibility to make the CMS menus have a more dynamic aspect.
all pins are initialized to pullup inputs per default. With resource PULLDOWN 1 PIN it is
possible to reconfigure the pin so it is a PULLDOWN input.
With this it's possible to prevent certain errors on some boards that have multiple pins connected
with an inverter and the pullup flows back via the inverter and pulls other pins low (see #7849)
Moved vtxtable frequency mode implementation into `vtx_common.c`.
This makes the implementation available for all vtx types and allows
for some code deduplication (see point below)
Removed band and channel tracking from tramp and rtc6705.
The hardware underlying both only support frequency mode and
the tracking is now done in `vtx_common.c` using the new factory flag.
Deleted vtxStringXXX. to continue supporting builds without
`USE_VTX_TABLE`, new infrastructure was created in
`drivers/vtx_table.c`, which loads fixed tables into vtxTableXXX
when built witout `USE_VTX_TABLE`. Individual vtx implementations no
longer need to load any band/channel tables. They only need to load
their individual power tables when built without `USE_VTX_TABLE`.
Additionally this allows for the next point:
Fully integrated vtxTableXXX and removed the old and no longer needed
indirection of frequency and power tables in `vtxDevice_t`.
Removed VTX_SETTINGS_* constants from `vtx_common.h` and replaced them
with the vtxtable equivalent.
rtc6705 implementation now uses power values from vtxtable instead of
using indices directly. It also stops using index 0. This makes it
consistent with other vtx implementations and is more user configurable.
It also cleans up `telemetry\srxl.c` which had to have a special case for rtc6705.
Finally, frequency entries in the vtxtable can now be marked as empty
by setting their frequency to 0. Betaflight will never allow a blocked
channel to be selected. This is useful for vtxtable index mode
(FACTORY flag set) where manufacturer-defined bands can be truncated
to ensure compliance with local laws and regulations.
- Initial
- Adjust load address of EXST firmware.
- Add helper script to pad an EXST binary to the expected size.
Padded firmware currently required due to a bug in the flash/dfu code
which causes anything less than a flash page size to be truncated when
uploading new firmware via the bootloader DFU.
- Minor linker script cleanups.
- STM32H7.mk change hardcoded TARGET_FLASH (384) to FIRMWARE_SIZE
- Delete unused configuration section entries from linker
scripts.
- Increase EXST firmware size to 448K.
It turns out 384K wasn't enough for a feature-complete firmware.
- Update pad-exst.sh to use 448K by default.
- Move the EXST file generation to the makefile.
[EXST] Embed firmware hash in ELF
- Add debug marker at end of CODE_RAM section.
It was found when transferring firmware to the H7 RAM via a BMP probe
using the 'gdb load' command, that the last few bytes were not
transferred, this debug marker is present to ensure all needed parts of
the firmware are present.
Example memory view of corrupted bytes at end of transfer:
0x2407DFAE DEB90000 DEB9DEB9 DEB9DEB9 DEB9DEB9 ..¹Þ¹Þ¹Þ¹Þ¹Þ¹Þ¹Þ
0x2407DFBE 000000B9 00000000 00000000 00000000 ¹...............
should be:
0x2407DFAE DEB9DEB9 DEB9DEB9 DEB9DEB9 DEB9DEB9 ¹Þ¹Þ¹Þ¹Þ¹Þ¹Þ¹Þ¹Þ
0x2407DFBE 00000000 00000000 00000000 00000000 ................
- Remove debug marker in EXST firmware.
STM32H750_EXST - Provide space for empty hash.
* Bootloader will run firmware if hash is empty, without re-verifying
RAM content against hash.
* CODE_RAM always shows as 100% usage.
STM32H750_EXST - Use a specific ELF section for a hash.
Two benefits:
1) CODE_RAM no-longer shows 100% full, since it is no-longer
padded/filled.
2) Prepares the code so that objcopy can be used to inject the hash
into the ELF.
STM32H750_EXST - Patch MD5 into ELF.
Process is now as follows.
* Binary generated (via make target dependency) so there is something to
hash.
* Binary copied (and padded).
* MD5 Hash computed.
* xxd patch file generated from hash.
* xxd hash patch applied to copy of binary at correct address.
* elf .exst_hash section dumped.
* hash injected into into dumped section.
* elf .exst_hash section updated with updated dumped section.
Replace EXST with USE_EXST.
Add documentation for the EXST firmware format.
Add table formatting to EXST documentation.
Update bootloader block.
Update H750 EXST linker script to use block format 0x00.
Use .exst.elf and .exst.bin on the exst files.
Add 'no checksum' to list of checksum hash methods.
Update EXST build system so it generates the following sets of files
obj/main/betaflight_TARGET.elf
obj/main/betaflight_TARGET.map
obj/main/betaflight_TARGET_EXST.elf
obj/betaflight_VERSION_TARGET.bin
obj/betaflight_VERSION_TARGET.bin.md5
obj/betaflight_VERSION_TARGET_EXST.bin
Update EXST build system to be more user-friendly.
* user-flashable files are generated in the normal place.
* Intermediate files are generated in `obj/main/...`
* Removes the `exst` goal.
* Adds .hex generation for EXST builds based on the patched .elf.
To build EXST targets, simply use `make TARGET=x` as normal and flash
the resulting `.hex/.bin` files rather than the .exst.bin file.
Developers can use either the `.elf` or patched `_EXST.elf` file as is
appropriate for their needs.
EXST documentation updated to match changes to build system.

* default is 5 seconds, which is too long when HSE gets stuck.
- Add PID-Audio support
Temporary override LINKER_DIR
Remove the giant `select` block that contained all the code to generate the elements and transition them to individual functions called only when the element is active. Simplifies the code and results in a performance improvement as it's not necessary to fall through the large `select` statement for every element that will be drawn. The individual functions and the element to function mapping are moved to a new `osd_elements.c` file.
Moved the OSD related code files to a new `osd/` directory.
Also pre-analyze the active elements and only process those that are active. This also saves processing as it's not necessary to loop through all 50 or so elements when only a couple are active.
Various other cleanup and removal of stale or unnecessary code.
In the default configuration the element drawing phase of the OSD task is reduced from ~51us to ~35us - resulting in about a 30% decrease in processing time.
Adds a new exit/save menu that can be displayed at any time using the yaw-right stick command. Yaw-left still functions as "back".
Allows the user to save their settings even while nested deep in multiple menus. Previously the user was required to back up all the way to the top level menu to save or exit.
Located under the Features top-level menu. Allows configuring the failsafe procedure (like selecting GPS-RESCUE if applicable).
Bounded with `#ifdef USE_CMS_FAILSAFE_MENU` so it can be disabled for space critical targets.
