No signals EEG, DIY-Cyton 8ch
Yarik

Hello dear!
I am new to neural interfaces
I collected the Cyton board from github, programmed it via pickit3, updated OpenBCI v3.1.2
I tried different versions of OpenBCI_GUI, OpenVIBE, but there are no signals from ADS1299.
I could not find RF22301-2, I used a UART master-slave from HC-05 (115200). Tried and wired UART, the firmware is loaded.
But there are no signals, sometimes a short signal skips.
I checked the chips on the TI ads1299 evaluation board and HackEEG Shield, they are working.
