Constructor Detail

ProxyAT91_PIO

public ProxyAT91_PIO(int pioSelector)

For use by the SPOT library only - to get a handle to an AT91_PIO use Spot.getInstance() and Spot.getAT91_PIO(int).

Method Detail

checkOwned

protected void checkOwned(int mask)

Specified by:

checkOwned in class AbstractAT91_PIO

available

public int available()

Description copied from interface: IAT91_PIO

Return the mask of available pins. An available pin can be claimed.

Specified by:

available in interface IAT91_PIO

Specified by:

available in class AbstractAT91_PIO

Returns:

mask

claim

public void claim(int mask,
                  int drive,
                  boolean claimForPeriphA)

Description copied from interface: IAT91_PIO

Lay claim to certain PIO pins.

Specified by:

claim in interface IAT91_PIO

Specified by:

claim in class AbstractAT91_PIO

Parameters:

mask - claimed pins

drive - bits set to 1 for pins to be controlled by PIO

claimForPeriphA - if true assign undriven pins to peripheral A; if false to peripheral B

release

public void release(int mask)

Description copied from interface: IAT91_PIO

Release claim to certain PIO pins

Specified by:

release in interface IAT91_PIO

Specified by:

release in class AbstractAT91_PIO

Parameters:

mask - released pins

disableIrq

public void disableIrq(int irq)

Description copied from interface: IAT91_PIO

Disable PIO interrupts for the specified pin

Specified by:

disableIrq in interface IAT91_PIO

Specified by:

disableIrq in class AbstractAT91_PIO

Parameters:

irq - A mask with a single bit set indicating the interrupt

enableIrq

public void enableIrq(int mask)

Description copied from interface: IAT91_PIO

Enable PIO interrupts for the specified pin

Specified by:

enableIrq in interface IAT91_PIO

Specified by:

enableIrq in class AbstractAT91_PIO

Parameters:

mask - the pio pin mask

waitForIrq

public void waitForIrq(int irq)
                throws InterruptedException

Description copied from interface: IAT91_PIO

Wait for the specified PIO pin to generate an interrupt. On exit, the pin is masked so that it will not generate another interrupt.

Specified by:

waitForIrq in interface IAT91_PIO

Specified by:

waitForIrq in class AbstractAT91_PIO

Parameters:

irq - A mask with a single bit set indicating the interrupt awaited

Throws:

InterruptedException
