Qt/C++ state machine to drive fear conditioning with sound stimuli and video acquisition
Experimental configuration is done by an INI file.
User interface is implemented in C++/Qt. The application provides a minimal user control to:
- choose a configuration file
- start / stop
- pause / resume
Provides low level timing of executing digital pulses. Communication is done via serial commands.
Classes:
- DriverSerial :: provides non-blocking serial message buffer
- DigitalPulse :: provides non-blocking digital pulse
- EventHandler :: provides interrupt safe event que
- HardwareLayout :: specific configuration based on FearGame setup, inherits from EventHandler
The experimental layout include specific signals encoding experimental stimuli.
