WavePlayer to trigger multiple waves

Claudina

Hello,

I would need to send 3 different sine waves (to operate a laser's AOM and scanning XY mirrors) to 3 different channels of the Bpod analog out module. I would ultimately need to trigger them simultaneously, in a specific state. Is it possible using WavePlayer?

Thanks!
Claudia

Hi Claudina,

You'd need to set a trigger profile:

W = BpodWavePlayer('COM3');
...
Load 3 waveforms with W.loadWaveform()
...
W.TriggerProfiles(1,: ) = [1 2 3]; % Set trigger profile 1 = waverforms 1, 2 and 3 simultaneously
W.TriggerProfileEnable = 'On';

Now in MATLAB, you can trigger all 3 with:
W.Play(1);

You can also load a serial message and then trigger all 3 from the state machine output actions:
LoadSerialMessages(1, ['P' 0]); % Note: this previously said ['P' 1], see comment on thread below
...
(in AddState's output actions)
{'WavePlayer1', 1}

Also see trigger profiles here.

I hope this helps!

Thanks Josh, I figured it out as you said. Only difference, the profile 1 gets triggered by the message LoadSerialMessages(1, ['P' [b]0]).
Thanks again!
