Interface BlinkOnPiMBean

All Superinterfaces:

AppMBean

All Known Implementing Classes:

BlinkOnPi

public interface BlinkOnPiMBean
extends AppMBean

Test and demo program BlinkOnPi as MBean.

Contrary to RdGnPiGpioDBlink the test and demo program BlinkOnPi makes full use of Frame4J by inheriting App.
Hence, additionally to own operations and properties here we can have also AppMBean.
Optionally, also UIInfo (implemented by App could be extended to make those also available as MBen operations (not recommended).

Method Detail

getLEDye

Boolean getLEDye()

The state of the yellow LED(s).

The yellow LED(s) are inverted only once in a cycle.

Returns:

true when ON

getLEDrd

Boolean getLEDrd()

The state of the red LED(s).

The red LED(s) are inverted twice in a cycle.

Returns:

true when ON

getLEDgn

Boolean getLEDgn()

The state of the green LED(s).

The yellow LED(s) are inverted twice in a cycle.

Returns:

true when ON

getLeBut

Boolean getLeBut()

The state of the button.

The button is low active. Hence, false means pressed.

Returns:

true when open, released

getLeBuz

Boolean getLeBuz()

The state of the buzzer.

The buzzer is an extra output. Default is pin 12. On the trafficPi shield pin 12 is a buzzer switched on by Hi (via a npn transistor).
This method returns the binary on/off state of the pin in question. When actuated via PWM 0..21 is considered as OFF (low, false) and 22..255 as ON (hi, true).

Returns:

true when active (Hi)

setLeBuz(Boolean), setLeBuzPWM(Integer), getLeBuzPWM()

getLeBuzPWM

Integer getLeBuzPWM()

The PWM state of the buzzer.

The buzzer is an extra output. Default is pin 12.

Returns:

0..255 which is 0..100% PWM

See Also:

getLeBuz()

setLeBuz

void setLeBuz(Boolean on)

The state of the buzzer.

setLeBuzPWM

void setLeBuzPWM(Integer pwm)

Set buzzer output by PMM.

Parameters:

pwm - 0..255 is 0..100% PWM

See Also:

getLeBuzPWM(), getLeBuz()

getCycCount

Integer getCycCount()

See the number of cycles.

As the duration of one cycle is 600ms (for BlinkOnPi it would take more than 40 years to overflow to negative.
Note: Java has no unsigned number type. In the C counterpart the type would be uint32_t.

Returns:

the loop count

See Also:

setCycCount(Integer)

setCycCount

void setCycCount(Integer cycCount)

Set the number of cycles.

See Also:

getCycCount()

getPiType

Integer getPiType()

Get the Pi type.
