E XAMPLE 6
The following refines example 1 and provides a more comprehensive example
of opening automatic enrollment for a simple assembly with one network
variable:
// MyCsmoData defines the enrollment details for the automatic ISI
// network variable connection offered by this device.
static const IsiCsmoData MyCsmoData = {
ISI_DEFAULT_GROUP, // Group
isiDirectionOutput, // NV direction
1, // Width
2, // Profile number (2 =
// SFPTopenLoopSensor)
76u, // Network variable type index
// (76 = SNVT_freq_hz)
0 // Variant (0 = standard)
};
// Call InitiateAutoEnrollment in response to isiWarm
void IsiUpdateUserInterface(IsiEvent Event, unsigned Parameter) {
if (Event == isiWarm && !IsiIsConnected(myAssemblyNumber)) {
// We waited long enough and we are not connected already,
// so let's open an automatic connection:
IsiInitiateAutoEnrollment(&MyCsmoData, myAssemblyNumber);
}
}
E XAMPLE 7
The following example opens automatic enrollment for a compound assembly
with four selectors, offering enrollment for member network variables 1 to 4
of an implementation of the SFPTsceneController profile (the nviScene,
nvoSwitch, nviSetting, and nviSwitch members):
// MyCsmoData defines the enrollment details for the automatic ISI
// network variable connection offered by this device
static const IsiCsmoData MyCsmoData = {
