Hi All, I am using Motorola SDK 3.0 version and CodeWarrior 5.1 version . In my project(for DSP56F803) if I include spi.h file (SpI libraries), during compilation it is giving error as follows: cannot convert 'unsigned int(*) (int, unsigned short * ,unsigned int) to 'unsigned int(*) (int ,const void *,unsigned int)' File name const.c line 2535 spiWrite_ This is the error we are getting only for DSP56F803, spiWrite function.And rest works fine. In this case we guess there is mismatch in library fuctions parameters. And also we have tried for DSP56F807 and DSP56F805 using uCos , it is working fine . Can anyone please suggest on this issue quickly. Thanks, With Regards, Rajarama __________________________________ |

Hi, A while ago, I had this error using the SPI port in slave mode on a 56F803. By setting "Relaxed Pointer Type Rules" in "C/C++ Language" of "Language Setting", I got rid of this error. Hope that will help. Regards, Bruno --- In , Rajarama Puranika <rpuranika@y...> wrote: > Hi All, > I am using Motorola SDK 3.0 version and CodeWarrior > 5.1 version .

Rajarama, To get rid of this error you need to enable 'Relaxed Pointer Type Rules' that is a setting under C/C++ Language Settings of your Targeting Settings inside of CodeWarrior. When you select this option, the compiler treats char* and unsigned char* as the same type. While prototypes are checked for compatiable pointer types, direct pointer assignments are allowed.
