No entrainment, hardware setup issue?
Hi everyone,
I've been playing around with ganglion chips and staring at various ssvep stimuli, however I've failed to achieve any entrainment or consistent peak at 10 hz with eyes closed. I've read previous posts about computer screens not being able to consistently create reliable stimuli, and tried the mindaffect interface to test my display. My display seems to be fine, and I wanted to see if I was messing up something on the hardware setup side. I've followed the ganglion setup page and the eeg setup page as well, and have included pictures of the front and back of my chips for your reference. If anyone has any tips it would be greatly appreciated, thanks!

Sorry here is the backside of the chips
Your switches are set correctly for common reference.
