 PPC/PMC-8260/DS1

 

Code Examples

This section contains C code examples which can be implemented into your driver 
software to enable communication between the host and the  PPC/PMC-8260/DS1 
firmware via the PCI bus. 

It assumes that the PowerSpan II PCI bridge has been fully initialized by the host’s 
PCI enumerator and is accessible. The code printed in bold at the beginning of the 
data definitions may require some modification to your host environment.

Data Definitions

/* some compatibility macros (e.g. for vxWorks) */

#define UINT32          unsigned int

#define sleep(s)        taskDelay(s*sysAuxClkRateGet())

/* Set this if host is big endian */

#define BIG_ENDIAN_HOST

#define LLSB(x)  ((x) & 0xff)          

#define LNLSB(x) (((x) >> 8) & 0xff)

#define LNMSB(x) (((x) >> 16) & 0xff)

#define LMSB(x)  (((x) >> 24) & 0xff)

#ifdef BIG_ENDIAN_HOST

#define LONGSWAP(x) ((LLSB(x) << 24) | \

                     (LNLSB(x) << 16)| \

                     (LNMSB(x) << 8) | \

                     (LMSB(x)))

#define NOLONGSWAP(x)   (x)

#else

#define LONGSWAP(x)     (x)

#define NOLONGSWAP(x) ((LLSB(x) << 24) | \

                     (LNLSB(x) << 16)| \
