Method Details

writeCV

public void writeCV(String CV,
 int val,
 ProgListener p)
             throws ProgrammerException

Perform a CV write in the system-specific manner, and using the specified programming mode.

Handles a general address space through a String address. Each programmer defines the acceptable formats.

Note that this returns before the write is complete; you have to provide a ProgListener to hear about completion. For simplicity, expect the return to be on the GUI thread.

Exceptions will only be thrown at the start, not during the actual programming sequence. A typical exception would be due to an invalid mode (though that should be prevented earlier)

Specified by:

writeCV in interface Programmer

Parameters:

CV - the CV to write

val - the value to write

p - the listener that will be notified of the write

Throws:

ProgrammerException - if unable to communicate

readCV

public void readCV(String CV,
 ProgListener p)
            throws ProgrammerException

Perform a CV read in the system-specific manner, and using the specified programming mode.

Handles a general address space through a String address. Each programmer defines the acceptable formats.

Note that this returns before the write is complete; you have to provide a ProgListener to hear about completion. For simplicity, expect the return to be on the GUI thread.

Exceptions will only be thrown at the start, not during the actual programming sequence. A typical exception would be due to an invalid mode (though that should be prevented earlier)

Specified by:

readCV in interface Programmer

Parameters:

CV - the CV to read

p - the listener that will be notified of the read

Throws:

ProgrammerException - if unable to communicate

readCV

public void readCV(String CV,
 ProgListener p,
 int startVal)
            throws ProgrammerException

Perform a CV read in the system-specific manner, and using the specified programming mode, possibly using a hint of the current value to speed up programming.

Handles a general address space through a String address. Each programmer defines the acceptable formats.

On systems that support it, the startVal is a hint as to what the current value of the CV might be (e.g. the value from the roster). This could be verified immediately in direct byte mode to speed up the read process.

Note that this returns before the write is complete; you have to provide a ProgListener to hear about completion. For simplicity, expect the return to be on the GUI thread.

Defaults to the normal read method if not overridden in a specific implementation.

Exceptions will only be thrown at the start, not during the actual programming sequence. A typical exception would be due to an invalid mode (though that should be prevented earlier)

Specified by:

readCV in interface Programmer

Parameters:

CV - the CV to read

p - the listener that will be notified of the read

startVal - a hint of what the current value might be, or 0

Throws:

ProgrammerException - if unable to communicate

confirmCV

public void confirmCV(String CV,
 int val,
 ProgListener p)
               throws ProgrammerException

Confirm the value of a CV using the specified programming mode. On some systems, this is faster than a read.

Handles a general address space through a String address. Each programmer defines the acceptable formats.

Note that this returns before the write is complete; you have to provide a ProgListener to hear about completion. For simplicity, expect the return to be on the GUI thread.

Exceptions will only be thrown at the start, not during the actual programming sequence. A typical exception would be due to an invalid mode (though that should be prevented earlier)

Specified by:

confirmCV in interface Programmer

Parameters:

CV - the CV to confirm

val - the value to confirm

p - the listener that will be notified of the confirmation

Throws:

ProgrammerException - if unable to communicate

getSupportedModes

@Nonnull
public List<ProgrammingMode> getSupportedModes()

Description copied from interface: Programmer

Get the list of ProgrammingMode supported by this Programmer. If the order is significant, earlier modes are better.

Specified by:

getSupportedModes in interface Programmer

Returns:

the list of supported modes or an empty list

setMode

public void setMode(ProgrammingMode p)

Description copied from interface: Programmer

Set the programmer to a particular mode.

Mode is a bound parameter; mode changes fire listeners.

Only modes returned by Programmer.getSupportedModes() are supported. If an invalid mode is requested, the active mode is unchanged.

Specified by:

setMode in interface Programmer

Parameters:

p - a valid node returned by Programmer.getSupportedModes() or null; null is ignored if Programmer.getSupportedModes() is not empty

getMode

getCanRead in interface Programmer

Parameters:

addr - the address to read

Returns:

true if the address can be written to; false otherwise

getWriteConfirmMode

@Nonnull
public Programmer.WriteConfirmMode getWriteConfirmMode(String addr)
