16-bit on bit changes
: 16-bit read when any bit changes from LOW to HIGH or
from HIGH to LOW.
16-bit on rising edge
: 16-bit read when any bit changes from LOW to HIGH.
Each bit indicates if a LOW to HIGH change occurred on each digital pin.
16-bit on falling edge
: 16-bit read when any bit changes from HIGH to LOW.
Each bit indicates if a HIGH to LOW change occurred on each digital pin.
8-bit strobe / 8-bit bit changes
: Reads bits 0-7 on the rising edge of the strobe
pin and reads bits 8-15 if bits 8-15 changed from LOW to HIGH or HIGH to LOW.
8-bit strobe / 8-bit bit rising edge:
Reads bits 0-7 on the rising edge of the
strobe pin, and bits 8-15 indicate if digital pins D8-D15 changed from LOW to
HIGH.
8-bit strobe / 8-bit bit falling edge
: Reads bits 0-7 on the rising edge of the
strobe pin, and bits 8-15 indicate if digital pins D8-D15 changed from HIGH to
LOW.
Digital Output
The Digital Output Window is accessed from the left side bar of the Hardware
Configuration Window and allows the user to set the properties of the digital
outputs. Digital outputs can function as spike detection monitors, timed function
generators, or triggered events.
Digital Output: Monitor Electrode
A digital output in monitor electrode mode will send a high pulse when a sorted
spike unit is detected on a defined channel.
Track Most Recently Selected
: When enabled, the channel selected in Spike
Panel, Single Neural Channel, or Raster Plot view is used as the monitor input.
Source
: Select which channel to monitor.
Monitored Units
: Select which spike unit classifications to trigger on.
