Porting function HIWARE to Cosmic: help!

Hi,

I have old project in Hiware C.

I want traslate it in Cosmic C.

I have same problem with this function defined in Hiware:

void Rampa (volatile unsigned int *PWM);

and used in main:

Rampa(&DCR0);

The problem is that in Hiware DCR0 is:

#define DCR0 (*(volatile unsigned int *)(0x17))

and in Cosmic is:

volatile int DCR0 @0x17;

Cosmic show this error in Rampa(&DCR0):

#error cpst7 interrupt_vector.c:227(12+4) incompatible argument type

Thanks for your help!

change

void Rampa (volatile unsigned int *PWM);

to

void Rampa (volatile int *PWM);

and it should work fine.

Of course you can also do it the other way around (add unsigned into DCR0 definition)

Regards,

Luca (Cosmic)

Thanks for your help!

Now the compiler show:

#error clnk Debug\new3.lkf:1 symbol c_xlcmp not defined (Debug\interrupt_vector.o )

I can post my interrupt code if it's necessary!

Thanks

my guess here would be you are not linking the right libraries: check in the manual what libraries correspond to the memory model you are using.

Thanks for your help! :)

I use small memory model, my micro is ST7LITE19

In Project-->Setting-->Linker-->

I have try to insert:

\COSMIC\CXST7_16K\Lib\libm.st7

and default crtsx.st7

but I have alwais the same error:

Running ST7 linker

clnk -lD:\Programmi\COSMIC\CXST7_16K\Lib -o Debug\new3.st7 -mDebug\new3.map Debug\new3.lkf

#error clnk Debug\new3.lkf:1 symbol c_xlcmp not defined (Debug\interrupt_vector.o )

#error clnk Debug\new3.lkf:1 symbol c_lreg not defined (Debug\interrupt_vector.o )

#error clnk Debug\new3.lkf:1 symbol c_uitol not defined (Debug\interrupt_vector.o )

The command: ''clnk -lD:\Programmi\COSMIC\CXST7_16K\Lib -o Debug\new3.st7 -mDebug\new3.map Debug\new3.lkf '' has failed, the returned value is: 1

exit code=1. :o :|

Thanks
