Function Documentation

int wge100Configure ( IpCamList camInfo,
const char *  ipAddress,
unsigned  wait_us 
)

Configures the IP address of one specific camera.

Parameters:
camInfoStructure describing the camera to configure
ipAddressAn ASCII string containing the new IP address to assign (e.g., "192.168.0.5"). If it is NULL or empty, the address in camInfo is used, and the configure packet is not broadcast.
wait_usThe number of microseconds to wait for a reply from the camera
Returns:
Returns -1 with errno set for system call failures. Returns 0 for success Returns ERR_TIMEOUT if no reply is received before the timeout expires

Definition at line 532 of file wge100lib.c.

int wge100ConfigureBoard ( const IpCamList camInfo,
uint32_t  serial,
MACAddress mac 
)

Sets the permanent serial number and MAC configuration for one camera

Warning:
: This command can only be sent once per camera. The changes are permanent.
Parameters:
camInfoDescribes the camera to connect to
serialIs the 32-bit unique serial number to assign (the product ID portion is already fixed)
macIs the 48-bit unique MAC address to assign to the board
Returns:
Returns 0 for success Returns -1 for system error Returns 1 for protocol error

Definition at line 1194 of file wge100lib.c.

int wge100Discover ( const char *  ifName,
IpCamList ipCamList,
const char *  ipAddress,
unsigned  wait_us 
)

Discovers all WGE100 cameras that are connected to the 'ifName' ethernet interface and adds new ones to the 'ipCamList' list.

Parameters:
ifNameThe ethernet interface name to use. Null terminated string (e.g., "eth0"). Empty means to query all interfaces.
ipCamListThe list to which the new cameras should be added
wait_usThe number of microseconds to wait for replies
Returns:
Returns -1 with errno set for system call errors. Otherwise returns number of new cameras found.

Definition at line 372 of file wge100lib.c.

static int wge100DiscoverSend ( const char *  ifName,
const char *  ipAddress 
) [static]
Todo:
We guess an IP by flipping the host bits of the local IP. Horrible, but won't usually be a problem even if we hit an IP that is already in use.

Definition at line 314 of file wge100lib.c.

int wge100FindByUrl ( const char *  url,
IpCamList camera,
unsigned  wait_us,
const char **  errmsg 
)

Finds a camera matching the given name

Names are of the form:

name://camera_name[@camera_ip][#local_interface]
serial://serial_number[@camera_ip][#local_interface]
any://[@camera_ip][#local_interface] 

A name URL indicates the name of the camera to be found. A serial URL indicates the serial number of the camera to be found. An any URL will match any camera, but if more than one camera is found, it will fail.

Optionally, the ip address that the camera should be set to can be specified by prefixing it with a @ sign, and the interface through which to access the camera can be specified by prefixing it with a # sign.

When an ip address is specified, it will be copied into the camera struct.

Parameters:
urlThe url of the camera to find
cameraThe structure to fill the camera information into
wait_usThe number of microseconds to wait before timing out
errmsgString containing a descriptive parse error message
Returns:
Returns 0 if a camera was found, -1 and sets errmsg if an error occurred.
