Types ¶
type ActiveBuzzer ¶
type ActiveBuzzer struct {
// contains filtered or unexported fields
}
ActiveBuzzer represent an active buzzer
func NewActiveBuzzer ¶
func NewActiveBuzzer(pinID int) *ActiveBuzzer
NewActiveBuzzer creates a new ActiveBuzzer instance
Example ¶
err := rpio.Open()
if err != nil {
fmt.Println("impossible to init gpio")
os.Exit(1)
}
defer rpio.Close()
// buzzer connected to GPIO pin 17
buzzer := activebuzzer.NewActiveBuzzer(17)
buzzer.Tone()
Output:
func (*ActiveBuzzer) StopTone ¶
func (buzzer *ActiveBuzzer) StopTone()
StopTone stops the buzzer tone
Example ¶
err := rpio.Open()
if err != nil {
fmt.Println("impossible to init gpio")
os.Exit(1)
}
defer rpio.Close()
// buzzer connected to GPIO pin 17
buzzer := activebuzzer.NewActiveBuzzer(17)
buzzer.Tone()
buzzer.StopTone()
Output:
func (*ActiveBuzzer) ToggleTone ¶
func (buzzer *ActiveBuzzer) ToggleTone()
ToggleTone toggle the buzzer tone Tone if stopped and stopped is toned
Example ¶
err := rpio.Open()
if err != nil {
fmt.Println("impossible to init gpio")
os.Exit(1)
}
defer rpio.Close()
// buzzer connected to GPIO pin 17
buzzer := activebuzzer.NewActiveBuzzer(17)
for i := 0; i < 10; i++ {
buzzer.ToggleTone()
}
Output:
func (*ActiveBuzzer) Tone ¶
func (buzzer *ActiveBuzzer) Tone()
Tone activate the buzzer tone
Example ¶
err := rpio.Open()
if err != nil {
fmt.Println("impossible to init gpio")
os.Exit(1)
}
defer rpio.Close()
// buzzer connected to GPIO pin 17
buzzer := activebuzzer.NewActiveBuzzer(17)
buzzer.Tone()
