Some STM32s are family footprint compatible, so migration can be 
reasonably straightforward if need-be and you are lucky

ARM is (in my opinion) a wonderful architecture and instruction set - 
just plain love it. Started tinkering in asm, then moved on to C. 
Interesting context switch registers to get your head around. Quite a 
comprehensive method to manage exceptions.

At the end of the day, you are battling against the datasheet for 
hardware, and compiler for sw.

One of the downside of the STM32 is that due to the flexibility, it 
can take some effort (initially) to get peripherals configured.

I can get you some demo code if you want.

Do you know the full part no of the STM32 of interest ?
