ADS1299EEGFE-PDK: Test Signals

RMoin

Hi,
I recently bought an ADS1299EEGFE-PDK, I can't get correct test signals when I connect my board to the computer. In scope, I just see lots of noise.

Hello Rasta, thank you for reaching out to us. Could you tell me more about your setup, what you have tried? Have you gone to page 27 where it talks about the analysis tools and used different tools there?

Can you send me your register configurations?

Matt Thank you for your kind attention, my previous problem about test signal is solved.
Now I have another question, is there any way to reach the output directly from the board. You know, I want to use the raw EEG signal and process it without a computer. How can I do that?

Hi Rasta,
Unfortunately you cannot, the internal test signals are exclusively inside the chip, when you select the "test signal" is disconnects the inputs from the MUX and connects to the test signal inside the chip. Thus you can't probe the inputs and see the test signal. Hope this clarifies it for you.
