Dear Sanworks,
I would like to connect an external digital signal to a behavioural port and in particular to the photo-gate in. I have look and couldn't find any information about it for Bpod R2. Could you please let me know what the voltage levels are, is the signal floating or pulled and what are the timing characteristics of the expected signals? My signal is 3.3V.
Also I couldn't find any schematics/board layouts of R2. Are you planning to release those?
If i'm not mistaken the digital Input is pin 1 on the rj45 socket counting from the left looking at the side of the bpod.
Thank you for your help!
