Hi.

How can I read device ID with software?

Is there any register that stores this value?

I would like to detect device on which program is running.

Or at least size of flash.

I'm using stm32f4 devices.

There are not any ST peripheral registers that say which device it is.

However, I have found in the reference manual - in the debug support, there is

register : ''DBGMCU_IDCODE

Address: 0xE004 2000''

(for a STM32F405 at least).
