| + | Note of course that this assumes you are in fact connecting Lines 0 and 1 on Port 0 to the "LED" header on the simulator board. Also power and ground (+5V and GND) need to be connected. | ||
| + | |||
| + | To read the state of the photobeams and push buttons, do this: | ||
| + | |||
| + | <code matlab> | ||
| + | inputSession = daq.createSession('ni'); | ||
| + | inputSession.addDigitalChannel('Dev3', 'Port1/Line0:3', 'InputOnly'); | ||
| + | |||
| + | %% take a sample of the status of the photobeams and switches | ||
| + | inputSession.inputSingleScan() % note for photobeams, a return value of 0 means detect; for switches, 1 means detect | ||
| + | </code> | ||
| + | |||
| + | As above, this assumes that Port 1 lines 0-3 are hooked up to the photobeams and pushbutton switches. | ||
| + | |||
| + | These basic commands can then be combined with appropriate loops and conditional statements, in accordance with your desired experimental logic, to produce a full experimental simulator. The actual running rooms are equipped with either the same NI DIO module (RR2, RR3) or something very similar (RR1, through Neuralynx instead of through NI). | ||
