Hi all,
I have a number of driver related function calls that I would like to
add as Primitive functions to yhc and yhi. For yhi
(yhc\src\runtime\BCKernel) I have added definitions to Runtime.c and
WrapPrimitive.c, in order to define and wrap stuff like "void
display_string(void)" where the function is declared in a
display.h/display.c file (this code controls the LCD display of the NXT).
So far I think I have this yhi part covered. My question is about where
these primitives are made known to the compiler so I can make
display_string visible to yhc programs. After adding this line to
Primitive.hs yhc hangs...
----------------------------------------------------------------------------------------------------
-- NXT Display
----------------------------------------------------------------------------------------------------
foreign import fastccall display_string :: CString -> IO ()
Oh it really shouldn't hang! just adding the function to Primitive.hs
should be enough. Send me the whole file and I'll have a go at compiling
it myself, see if I can make anything of it :-)
Cheers
Tom
