} SYS_STATUS;
Defines system status structure. System status is obtained with the help of
S817_GetStatusInfo function for a group of channels (1 .. 4, 5 .. 9, etc.).
chanData[4]
An array of 4 structures of CHAN_STATUS type (see above), one for each of 4
channels belonging to a group.
extErrAddr
Internal use, do not modify.
dspAddr
Internal use, do not modify.
fwVer
Firmware version (major in bits [31:16], minor in bits [15:0] ) .
inPciRead
The board is attempting to read data from host. Normally is 0.
inPciWrite
The board is attempting to write data to host. Normally is 0.
reserved[8]
Internal use, do not modify.
EXTERR
typedef struct {
unsigned int tick;
unsigned int ecode;
unsigned int reserved[2];
} EXTERR;
Defines the extended error structure. The extended error information for each capture
channel is kept in an array of
EXTERR elements of the size SYS_EXTERR_BUF_SIZE
(defined in s817.h , currently 64) . This array is copied from the board to the buffer in
the host’s memory by a call to S817_GetExtErrInfo (see below). The first element of the
array is used to keep track of the total number of errors registered for a given capture
channel (in
.tick member), the rest are used as a ring buffer. Each valid entry of the
ring buffer keeps the information on the type of the error ( .ecode ) and the time of
occurrence in units of the 1 ms timer ( .tick ). Let’s assume, for example, that the buffer
