Determine CPU Type at Run-time

Hi,

I am developing an application that will be targetted at a number of STM32F/STM32L hardware platforms and wondered if it was possible to determine the CPU type at run-time. CPUID is useful to determine ARM core details etc. and thought there would be an equivalent register for the STM stuff.

Regards

    Thank you Andrew for that. I even searched the TRM for 'device ID' and must have missed it somehow.

    Anyway this is just what I am looking for.

    Like DEV_ID in DBGMCU_IDCODE?

    Use that to auto-speed F4 parts, ie optimum PLL setting and AHB/APB dividers.

    Should be good - but doesn't always work:

    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
