ZUNO_SWITŠ”H_BINARY()
This macro is used to setup binary switch channel for Z-Uno board using ZUNO_SETUP_CHANNELS.
Z-Uno understands two ways to define a channel: using getter function and using a variable.
-
With getter definition the getter function is called each time a value is requested. This allows to do some calculus before returning a value.
-
With variable definition Z-Uno will automatically return the variable status. This allows to minimize your code.
ZUNO_SWITCH_BINARY(getter, setter)
getter
pointer to a user defined function, which is supposed to return current value for this channel.
setter
pointer to a user defined function, which is called when new value is received for this channel.
Functions getter should return 0 for Off and any non-zero value for On
BYTE getter(void)
Functions setter accepts next values:
void setter(BYTE value)
Channel generated using this macro will have Z-Wave Device Class GENERIC_TYPE_SWITCH_BINARY / SPECIFIC_TYPE_POWER_SWITCH_BINARY with Switch Binary Command Class.
ZUNO_SETUP_CHANNELS(ZUNO_SWITCH_BINARY(getterFunction, setterFunction));
void setup() {
...
}
void loop() {
...
}
BYTE getterFunction() {
return currentValue;
}
void setterFunction(BYTE newValue) {
...
}
ZUNO_SWITCH_BINARY(variable, NULL)
variable
variable that stores the current value for this channel. 0 for Off and any non-zero value for On.
Variable change can be detected using function zunoIsChannelUpdated(channelNum).
ZUNO_SETUP_CHANNELS(ZUNO_SWITCH_BINARY(lightStatus, NULL));
byte lightStatus = 0;
void setup() {
...
}
void loop() {
...
if (zunoIsChannelUpdated(1)) {
// Do something on new value received via Z-Wave
}
...
lightStatus = ...;
