* Outdated apps: add api-light-usage * Gpio: update SD card CS pin settings * API-power: added fns to disable/enable external 3v3 dc-dc * API-gpio: separated SD card detect routines * Resources: removed sd cs pin * SD card: low level init now resets card power supply * App SD-filesystem: use new card detect fns * SD card: fix low level init headers * SD card: more realilable low level init, power reset, exit from command read cycle conditionally * App SD-filesystem: led notifiers, init cycling * SD card: backport to F4 * SD card: handle eject in init sequence * SD card: api to set level on detect gpio * SPI: api to set state on bus pins * SD card: set low state on bus pins while power reset Co-authored-by: coreglitch <mail@s3f.ru> |

Bootloader
Bootloader must be flashed first.
Detailed instruction on how to compile and flash it you can find in bootloader
folder.
OS
CMSIS-RTOS2 over FreeRTOS
Platform code
CMSIS, Freertos and HAL files are generated by CubeMX.
You can find platform code for STM32WB55 version in f4
folder:
├── Inc # CubeMX generated headers
├── Src # CubeMX generated code
├── api-hal # Our HAL wrappers and platform specifics
├── ble-glue # BLE specific code(Glue for STMWPAN)
├── f4.ioc # CubeMX project file
├── startup_stm32wb55xx_cm4.s # Board startup/initialization assembler code
├── stm32wb55xx_flash_cm4*.ld # Linker scripts
├── target.mk # Makefile include
Working with CubeMX:
- Download CubeMX from st.com
- Open
*.ioc
file - Do whatever you want to
- Click
generate code
- After regenerating, look at git status, regeneration may brake some files.
- Check one more time that things that you've changes are not covered in platform api-hal. Because you know...
Flipper Universal Registry Implementation (FURI)
FURI is used to:
- application control (start, exit, switch between active)
- data exchange between application (create/open channel, subscribe and push messages or read/write values)
- non-volatile data storage for application (create/open value and read/write)
Read more at FURI page
FS (not implemented)
File system is used to volaile storage some files (config, application data, etc.). There are some folders mounted to different volumes:
/usr
for store static data like assets, menu items. Build system add files to usr while building. It can be useful for exchange some static data between application. For example, your app can add link to itself to Plugins menu items file, user will see your app and can call it from this menu.- Specially
/usr/etc-default
folder contains default configs for apps. Bootloader hasfactory default
options to reset applications config. Also when new app is bootstapping, system copy files from default config folder to/etc
. /etc
for store configs of application. This volume not overwrite during flashing./var
for store some application data (saved keys, application database, logs). This volume also not overwrite during flashing./media/*
mounted if SD card is inserted.
Flipper applications
Each flipper functionality except OS/HAL/FURI doing by Flipper application. Some application are called at startup, the rest are called by the user (for example, from menu).
(you can see some examples)
For exchange data between application each app expose own record in FURI. You can subscribe on/read record to get data from application and write to record to send data to application.
