Field Details

ZERO_ZERO

public static final ChipLocation ZERO_ZERO

The location (0,0), which is in the bottom/left corner and typically the Ethernet-enabled chip for the lead board of an allocation. It is also typically the boot board of an allocation.

ONE_ZERO

public static final ChipLocation ONE_ZERO

The location (1,0), which is the one to the east/right of the bottom/left corner.

This location has special meaning on a 4 chip board.
