• Yes I did use OpenBCI_32bit_16channel repository.  I honestly don't know what happened. One day it was working fine the next day it wasn't. So I'm afraid I can't be of any help in replicating the problem.  Thank you for all your help!

• Yes I did say that in my post from May 25th (http://openbci.com/forum/index.php?p=/discussion/comment/2387/#Comment_2387) I must admit I hadn't thought to try just the main board by itself last week since I only ever use 16 channels. So after test…

• Well now I'm not even getting anything when I send a "?". I've tried re-uploading the firmware again and nothing changed.  Is this fixable?

• Well I uploaded the new firmware. It took a couple of tries but I followed the instructions in another post (chipKIT uploading tips and restarting bootloader) and was successful. However now I keep getting the error "init timeout...retry initializat…

• Yes it is a strange problem. I did as you suggested and the following are the screenshots and output from processing. Even though the board and the daisy are healthy, I am still missing 8 channels of data.  1) 16 Channels nothing connected - sc…

• So I tried running it using the latest processing sketch on another windows computer and a Mac. It didn't fix the problem.

• No I haven't. I'll look around and see what computers I can borrow.

• The CS2 pin seems pretty firmly in place. We tend to not take the daisy off so there shouldn't have been too much wear on it.  Do you know if there are any loaners available? Unfortunately I was in the middle of an EEG study when this happened so …

• Thanks for the suggestions.  After experimenting the problem seems to be resolved once we updated the driver, updated our Labview drivers, and re-soldered the daisy onto the board.  The past two weeks we have been using it every day and the pr…
