Enum ControllerType

java.lang.Object

java.lang.Enum<ControllerType>

org.lsst.ccs.drivers.parker.ControllerType

All Implemented Interfaces:

Serializable, Comparable<ControllerType>

public enum ControllerType
extends Enum<ControllerType>

Contains all supported Parker ACR-like controller types. All ACR controllers use the same AcroBasic language for motion programs. They differ in where you look for the address of the global variable area and whether memory is addressed per 32-bit word or per byte.

Method Detail

values

public static ControllerType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ControllerType c : ControllerType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ControllerType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getSystemPointerAddress

public int getSystemPointerAddress()

Gets the address at which the pointer to global variables is found. This address varies from one model of controller to the next. At this address is a 32-bit pointer to the global data area. The first 32-bit word in this area, if it exists, is an unsigned integer count of the the number of words of global variables. The variables come immediately after and each takes up two words.

Returns:

Either zero (no global variables) or the address of the global area.

getWordBump

public int getWordBump()

Gets the number of addresses occupied by word in controller memory. For a byte-addressed memory this will be four while for a word-addressed memory it will be one. If the global data area starts at address glob then the address if the i'th global variable, counting from zero, will be at glob + wordBump*(1 + i).

Returns:

The word size.
