APPENDIX A: SNAP ETHERNET-BASED BRAIN MEMORY MAP
Starting Address Length Type Description
FFFF F0C0 0044 4 UI Point 1: Point Type (unsigned integer).
Use 0x0000 0100 for digital inputs.
Use 0x0000 0180 for digital outputs.
For analog types, see table on page 19.
FFFF F0C0 0048 4 UI Point 1: Point Feature (unsigned integer)
Digital feature values:
0x0000 0001 for counter input (configures and starts the
counter)
0x0000 0004 for simple quadrature counter input
0x0000 0041 quadrature counter input with index. For
quadrature counter information, see page 21.
Analog feature values: none at present
To disable point features, use 0x0000 0000
FFFF F0C0 004C 4 F Point 1: Point offsets (float)
FFFF F0C0 0050 4 F Point 1: Point gains (float)
FFFF F0C0 0054 4 F Point 1: Point high scaling factors (float)
FFFF F0C0 0058 4 F Point 1: Point low scaling factors (float)
FFFF F0C0 005C 4 -- Point 1: Reserved
FFFF F0C0 0060 4 F Point 1: Average filter weight. (float)
