Hi wjcroft. I tried Cassani's toolkit and it didn't have a problem. The core acquisition section was very similar to my own. I tried dropping it into my main code but acquisition became really erratic, not sure why.However, now I know what the pr…

I've done this many times before for work and personal projects. I've got multiple circular buffers between the low level hardware buffer and the processing loop. I WAS using the hard-coded queuing built into Labview to control the interplay betwe…

It works fine detecting alpha waves using the closed-eye test but all my spike troubleshooting has been with no connections the board.My RMS noise is sub uvolt so that looks good. Yes, I seem to be getting the packets and I've even examined the dat…

Hi, I'm back after some lengthy troubleshooting. I've dropped the latency timer to 1 ms and I am using the V3 software (everything was downloaded late last fall).I'm doing all my testing with the PCB unattached to anything. Here are some interestin…

thanks for the detailed info, I will let you know if I trace something down.I'm not wearing the helmet; the board by itself is sitting next to the laptop but it doesn't seem to make a difference whether it's 2 in or 2 ft away. It also comes and goe…

Thanks, I never would have considered Misumi for a USB cable!I think I have to return to this problem because the median filter that worked was also messing with my signal data. Can you please describe what exactly the dongle red led indicates? Is…

I have thought about moving to a wireless-signal-free location to test it out. I will consider the channel change though if I keep having a problem. It seems erratic; last night it ran without any streaming problems. My environment is too saturat…

Actually I do mention that the red light blinks at the same time I get big spikes in my data that throw off running averages and such (in my application I consider that major havoc). My local wireless pollution is high though and I figured that I'm …

I recently had a problem like this and it went away when I ran it as administrator. (not sure but might try that with the hub as well)

addendum to my last post:according to an old post about blank GUI windows: 'This page suggests checking your graphics driver(s). They need to be compatible with the latest OpenGL, https://github.com/processing/processing/wiki/OpenGL-Issues' Bu…

I checked and have the latest drivers for my wimpy obsolete on-board graphics chips and it is only 2.1. The latest is 4.5. This is a very old laptop.I get a blank GUI window so not sure what else to troubleshoot.

How do I erase or comment 'solved' when I am replying to my own post?Anyway, this question is moot. I got the accel IC footprint mirrored, blegh! I'm surprised I was able to get any data from anything! I just removed the IC and I'm getting non-ze…

The question about the blinky LED is true; about twice a second and always blinky if no code has been loaded. It must be true because it is working.As for the other questions, they became unnecessary once I tried reprogramming everything. I believ…

SOLVED: The answer is yes, a new chip will behave as described. I've successfully loaded the cyton code and it runs.

Great! Thanks, sorry to act forum-ignorant, thought I had did my searching but distracted by not feeling well.

I recently finished building my own Mark III and it was a bitch until I got my printer dialed in. It helps a lot to really know your printer and how to tune it for a particular job. When I saw a picture of the helmet my first thought was "wow, tha…

I can't seem to edit my original post so I will put it here. I worked out I need AVRdude from Github but I can't tell which hex file I need. thanks
