How to use STM32F405

I want to use the “STM32F405” chip.
What should I do?


It seems that the chip is not on any Mbed OS Enabled board.
I would start to compare which supported board is closest to STM32F405. Maybe NUCLEO-F401RE.
Then you can modify the code so that it is similar as your board:

I would also try Mbed OS first with any supported board before starting custom porting.
