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
