Synchronization
This section describes how synchronization is achieved
Synchronization during recording
Note that pins are only switched either to send trial information or after a state change (AND after the flip happened!) The idea is that both trial information and state information can be sent via the same channel. Details are described below.
Resulting 8 pin state signal
Values of 252 to 255 are preserved for indicating start of trial/state information and in-between trial information stoppers:
- 252: indicates start of trial information
- 254: in between trial information to define trialinfo packages
- 253: end of trial information
- 255: start of state information
Note that due to preserved values, a trial information package maximum value is limited. For example, to encode the date first package would be first 2 digits of the year, second package the last 2 digits of the year, third package the month and fourth package the day. That way none of the packages reaches a value of over 100. Trial information is sent during INI (state 1), during the other states the stat value reflects the current state.
