This repository aims to provide handlers for the go-gpiocdev Library's gpiocdev.WithEventHandler line option.

It's still under development with two sensor added to the library without tests are performed.

• Each handler is a stuct that implements IEventHandlers generic interface.
• Measure() method is used as the main handler that does the logic/calculation/measurement for the sensor data. This should be passed to WithEeventHandler() method.
• Subscribe() is for listening measurement if immediate responses are needed when a measurement is done. It's a channel type.
• CloseChannels() is the method that closes the above channel. Best to be called when usage is no more required.
• GetMeasurement() is the method that return the latest measurement.

A simple example might look like the following:

lfs :=factory.InitializeEventHandlerFor(sensors.FLOW_SENSOR, "gpiochip0", "GPIO4", 0.002222222)
defer lfs.CloseChannels()

gpiocdev.RequestLine("gpiochip0", pin, gpiocdev.WithPullUp, gpiocdev.WithBothEdges, gpiocdev.WithEventHandler(lfs.Measure))

for {
    fmt.Printf("%f Liters Flowed",<-lfs.Subscribe())
}

Please refer to the Examples section to see more details examples for each sensor.
