GUI control for all µLEDs
- Grouped control
- Independent control
Pattern generation, with constants and ramps
For use with our 12 channel µLED NeuroLight stimulating headstage
Digital inputs for automatic control
Programmable Digital outputs for time-locking with neural recordings
External control of stimulating start/stop

Digital Inputs

The NeuroLight Stimulator channels can be started and stopped through the digital input pins on the stimulator hardware.
Each channel has a corresponding digital input pin. A high (+3.3V) level on a pin will start the channel assigned to that pin, and a low (0V) level will stop the channel.
The channel will only start if it’s armed.

Digital Outputs

The NeuroLight Stimulator channels can be monitored through the digital output pins on the stimulator hardware.
By default, the DO pin for each channel goes high (+3.3V) when that channel is playing, and low (0V) when it is stopped. This behavior can be altered in the settings.

The NeuroLight Stimulator in combination with optoelectrodes such as the NeuroLight Optoelectrode allows for simultaneous recording and optogenetic stimulation.

The firmware allows current waveforms to be stored in the Stimulator and played back through the headstages on demand to illuminate the micro LEDs on the probe for Optogenetic stimulation. Some possible waveform examples are shown below:

Digital Inputs

The NeuroLight Stimulator channels can be started and stopped through the digital input pins on the stimulator hardware. There are 32 digital inputs on the NeuroLight Stimulator. There are two modes of operation: single-bit mode and strobed word mode.

Digital Outputs

The NeuroLight Stimulator channels can be monitored through the digital output pins on the stimulator hardware. There are 32 digital outputs in the NeuroLight Stimulator. Each digital output can be mapped to one particular output channel and can be configured to report one of three things: whether the channel is actively playing a pattern, actively playing a waveform, or whether the output is non-zero. By default, the DO pin for each channel goes high (+3.3V) when that channel is playing, and low (0V) when it is stopped. This behavior can be altered in the settings.

The NeuroLight Stimulator in combination with optoelectrodes such as the NeuroLight Optoelectrode allows for simultaneous recording and optogenetic stimulation.
