| How to introduce a new version of stm32cube: |
| ============================================ |
| |
| Original STM32Cube tree structure has been modified to a minimum |
| structure for a better fit into Zephyr. |
| STM32Cube is divided into drivers and soc section, with: |
| |
| drivers/ |
| include/ contains Cube HAL/LL files from: |
| STM32Cube_FW_F1_VX.X.X/Drivers/STM32YYxx_HAL_Driver/Inc/* |
| src/ contains: |
| STM32Cube_FW_F1_VX.X.X/Drivers/STM32YYxx_HAL_Driver/Src/* |
| soc/ contains STM32 CMSIS files from |
| *STM32Cube_FW_F1_VX.X.X/Drivers/CMSIS/Device/ST/STM32F1xx/Include/* |
| *STM32Cube_FW_F1_VX.X.X/Drivers/CMSIS/Device/ST/STM32F1xx/Source/Templates/system_stm32f1xx.c |
| |
| One file needs to be renamed: |
| driver/include/stm32f1xx_hal_conf_template.h |
| into: |
| driver/include/stm32f1xx_hal_conf.h |
| |
| |
| In order to enjoy ST CMSIS definitions: |
| *CONFIG_HAS_STM32CUBE should be defined |
| *stm32yyxx.h should be included in soc.h |
| **E.g.: #include <stm32f1xx.h> |
| |
| In order to use STM32Cube HAL, these files should be compiled: |
| In /ext/hal/st/stm32cube/Kbuild : |
| obj-y += stm32yyxx/drivers/src/stm32yyxx_hal.o |
| obj-y += stm32yyxx/drivers/src/stm32yyxx_hal_rcc.o |
| obj-y += stm32yyxx/soc/system_stm32yyxx.o |
| Plus add HAL driver file (when needed): |
| obj-$(CONFIG_SERIAL_HAS_DRIVER) += stm32yyxx/drivers/src/stm32yyxx_hal_uart.o |
| |
| |
| Additionally, in order to use STM32Cube LL (when needed): |
| *include stm32yyxx_ll_usart.h in soc.h |
| **E.g.: #include <stm32f1xx_ll_usart.h> |
| |
