Bare Metal Programming on STM32WB55 or STM32F10

[KGupt.1]

I want To do Bare Metal Programming on STM32 using STM32CubeIDE.

have (STM32WB55 and STM32F103).

what all header files and source files are required to use peripheral registers and make own Device driver. For E.g: in AVR 8 bit MCU for doing bare metal we simply have to add iom328.h or iom2560.h header file that will include all the peripheral registers of the MCU and we can easily make LL.

Same way out what are the Header files required for doing it with STM32

CMSIS: is like Initialize our processor and includes its registers.

So what all header files to be included for programming STM32F103 and STM32WB55

The appropriate one from https://github.com/STMicroelectronics/STM32CubeF1/tree/master/Drivers/CMSIS/Device/ST/STM32F1xx/Include, and those from https://github.com/STMicroelectronics/STM32CubeF1/tree/master/Drivers/CMSIS/Include which are included from the above, directly or indirectly.

You don't really need system_stm32f1xx.h, I usually replace it with an empty file.

You'll need also a startup file and a linker script, if the IDE won't supply those (I don't use Cube).

So Just. h file of the MCU which I am using

and the .h file of the Processor which is in My MCU.

These two are required to use internal registers?

One more thing .... .h file of the MCU contains the memory mapping of the peripheral registers.

but I can't get what does .h file of the CMSIS does? like does it initialize my processor?

CMSIS is for core support, h file from cube are for peripherals.

CMSIS package include tamplates for startup and linker script.

This will be all .h files. You don't need any *.c file.

> These two are required to use internal registers?

The "processor" .h in fact consists of two or three .h mutually calling each other - just try and you'll find out quickly.

You can look inside the files to find out what do they contain.

For "processor initializing" you'll need a startup file - usually a .s (assembler) file which does the usual registers clear required by C, and contains the vector table. Look at the examples which come with Cube.

This has a lot of I want a manual transmission, how does the clutch work, feel to it....

[KGupt.1]

So Directly I just need to include all the Header files which are over their in CMSIS folder as it contains all the .h files for my core(cmsis_armcc.h,cmsis_gcc.h, etc ) and also STM32f103.h file and system_startup
