Class EDemoBoard

  com.sun.spot.sensorboard.EDemoBoard

All Implemented Interfaces:

IDemoBoard

public class EDemoBoard
extends Object
implements IDemoBoard

This class reflects all of the functionality of the EDemoBoard to a SPOT application. The old methods bindServo() & bindToneGenerator() have been removed. Please now use "new Servo()" & "new ToneGenerator()" passing in the IOutputPin or IOPin that they should use. This is a facade class. All the real work is done in the EDemoController class.

setPWM

public void setPWM(IOutputPin pin,
                   int duty)

Request the controller maintain a pwm signal on a gpio pin. Set the duty to 0, to turn off an existing pwm signal. The control of this pulse generation is coarser then that available using the startPulse method. Note: that the pwm signal will stop during deep sleep and resume when deep sleep is over.

Parameters:

pin - output pin to send PWM signal to

duty - duty cycle out of 255 slices

startPulse

public void startPulse(IOutputPin pin,
                       boolean dir,
                       int usec)

Ask the controller to issue a pulse on the indicated pin. The pulse is accurate in terms of microseconds but the start time of the pulse may be affected by a bit of latency. Only one pulse may be active at a time. Minimum pulse length is about 25usec.

Parameters:

pin - output pin to issue pulse on

dir - direction of desired pulse: true = high, false = low

usec - length of pulse in microseconds [1:65535]

getPulse

public int getPulse(IInputPin pin,
                    boolean dir,
                    int timeout)

Ask the controller for a measurement of an incoming pulse on some input pin. The pulse width can range from 25usec to 65536usec. Pulses longer than 65536usec will be recorded as 65536usec. Timing will begin at the edge of the pulse in the indicated direction and timing will stop when the opposing edge is seen. If timing is not started in time for first edge, the next pulse will be the one measured. Only one pulse measurement may be active at one time. Calling getPulse() again while a previous call was still pending will terminate the old call and may introduce additional latency before checking for the initial edge begins.

Parameters:

pin - input pin to measure pulse on

dir - direction of desired pulse: true = high, false = low

timeout - how many milliseconds to wait for start of pulse (set to 0 for no timeout)

Returns:

length of measured pulse in microseconds or zero if no pulse seen before timeout

Note that this is a dangerous thing to do, you can in fact change something that is unrecoverable. You should only use these functions if you know what you are doing, and you should not use register values that are not defined in Atmega.java

Parameters:

reg - register to set value of

val - value to use in operation

andRegister

public void andRegister(int reg,
                        int val)

Perform an AND assignment to one of the registers in the Atmega88 controller. This method will result in a '&=' of the value passed in with the current value in the register. Note that this is a dangerous thing to do, you can in fact change something that is unrecoverable. You should only use these functions if you know what you are doing, and you should not use register values that are not defined in Atmega.java

Parameters:

reg - register to set value of

val - value to use in operation

getRegister

Peek method for the atmega firmware. This method allows for reading values straight out of the low level control registers on the microcontroller. Use only the register values as defined statically in the Atmega.java and Atmega88.java files.

Parameters:

reg - Register to read value from

Returns:

current register value
