RE: [motoroladsp] SDK SPI compile error
If you turn on the "Relaxed Pointer Type Rules" box
in the Metrowerks Target Settings panel for
C/C++language settings, the error
disappears!!!

Subject: [motoroladsp] SDK SPI compile error
Hi
I'm trying to use the SDK to configure a 56F803 SPI
peripheral. I start
with #define INCLUDE_SPI in appconfig.h. (I already
have #define
INCLUDE_IO.)
As soon as I #define INCLUDE_SPI, I get the following
compile error: (I'm
using 5.0.4).
I haven't written any SPI code yet, just #defined
INCLUDE_SPI.
Can anyone suggest where I should look to untangle this?
It seems to be a prototype mismatch between spiRead and
spiRead (?)
spidrv.c defines the middle param as a pointer to
UWord16. io.h and
spidrv.h seem to think it should be a void pointer.
Could this some mis-match between 5.0.2 and 5.0.4? I
updated, but would
have assumed that I imported all the relevant files.
Maybe I need to recompile some lib, again?
Thanks in advance. I'm afraid to charge in and
start changing SDK code.
All I did was #define INCLUDE_SPI!
