I'm trying different appraoches for a software trigger but I also built the photoresistor to measure latency and jitter. If I understood it correctly, I only need to send /2 to the board and I should read the trigger. Then, what would be the easi…

The application will be distributed to users that can buy OpenBCI but can't solder the photoresistor. I am currently using LSL but for simplicity for the users I'd rather have a standalone app. I can log the time when start is sent to OpenBCI and …

I can't use hardware markers, it's one of the limitations I have. I was looking for a solution that synchronizes EEG and stimulus via software triggers or timestamps. I am using high precision timers to control and log the stimulus.

I tried to send the following command: 'x 1 0 6 0 1 0 0 X' to collect EMG data using Ch1N and Ch1P instead of using the reference SRB2. However, after changing it, my signal is zero (for channel 1 and all the channels). I tried changing it back to '…

Thanks so much for the responses. I finally figured out the problem. The signals were correctly collected but the filter I was using in Matlab was not filtering correctly. After correcting it, I got a similar signal.

Thanks so much. I'll try with 250Hz sampling rate using a bandpass of 10-125Hz. Hopefully that works.

I'm still in the design phase. I have experience in EEG but I've just started with EMG. All the papers I found, use 1kHz widn bandpass 20-500Hz, that's why I assumed those were the reqs. Do you know any good reference (paper/blog/site)? I was th…
