Interesting. Perhaps something like foreign import "volatile &periphBase" :: Ptr Word32 which will declare extern volatile uint32_t periphBase in the file, then you would just have a linker symbol periphBase at 0x4000000. (or just import a value with zero and do pointer arithmetic like you do) John On Wed, Mar 6, 2013 at 6:05 AM, Kiwamu Okabe <kiwamu@gmail.com> wrote:

What do you mean by raw memory? I don't think the volatile should be needed in general for C allocated variables, but perhaps you are writing to hardware registers?
Yes. I would like to write to hardware registers.

We can do real programming with pure Haskell code, if poke function is used.
