Cyton GUI output freezes with Daisy, but works fine without (8 channels)
Hello,
In 2015 around I sponsored OPENBCI with kickstarter and bought the Cyton BCI with daisy.
Daisy came with soldering work.
So first I did somme eeg sampling with Cyton without daisy.
Years later (now) I started the soldering and afterwards I thought daisy was perfect for hooking on the Cyton.
Although 8 channels are fine with Cyton with daisy on board the channel display freezes an no data were sampled. (s. attachments)
could some one please explain what is wrong ?
I would be very glad to get your hints...
kind regards
merlin
(no magic at all :-)

Hi Merlin,
Since your Cyton from 2015 came with the old V1 firmware, have you upgraded the Cyton firmware to latest levels? Without upgrading, there are known compatibility issues with the current GUI and old firmware.
Regards, William
thank you for your comment. I keep you informed as soon I am done.
kind regards
merlin

Happy new year...
I tried upgrading resp. sketching as described for upgrading for daisy:
every trial ends with with "bad type cpu".
where is the mistake ?
thank you

Merlin, thanks for your efforts. Take look at this thread, which I found using the Google Advanced Search button in the upper right column (on "bad CPU type"):

Apparently the issue you are seeing from the PIC32 gcc compiler, is that it is built for 32 bit MacOS. As of Catalina, 32 bit apps are no longer supported. As the fastest workaround, I recommend you try to locate a Windows machine and build there. All versions of Windows can run both 32 and 64 bit apps.
Mentioning Richard @retiutut, and Shirley @Shirley; should we place a warning / workaround in the docs, mentioning the macOS 32/64 bit compiler issue? Would also be great if there WAS a 64 bit gcc someplace. Seems possible since Microchip still supports PIC32.

Regards, William
if you really wanted a mac gcc build, you could try to build a 64-bit gcc for PIC32 from the source code (I have not tried this):

Bill and Merlin, thanks.
If @merlin wanted one other avenue for his present Mac, one could install the free VirtualBox software (virtual machine emulator),
https://www.virtualbox.org/
Then install a free image of Windows 10,
https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
Then build using the Windows instructions from OpenBCI.
I was successfull compiling sketching and flashing with my 1 year old macbook.
I flashed with chipkit 1.3.1 and openbci including daisy.

what can I do...
is it a soldering problem?
thank you for your assistance.
Your 2015 Cyton almost certainly had the V1 firmware. Both in the PIC32 Cyton mainboard and the RFduinos (dongle and mainboard) that handle the radio communications. Did you update ALL THREE of this chips firmware?

Beyond the old firmware issue, you may also have issues with the connection pins between Cyton and Daisy. Especially since you soldered them yourself.
