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.

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:

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.
