Other Parts Discussed in Thread: ADS1299

Hello,

I have questions about ads1299EEG-FE.

Q1. i got the esults when setting like below picture.

CH1+ & CH2+ set my forehead

pin33 of J6 connected earlobe

i want to get EOG signal when blinking.

i think that single ended input set. Am i wrong?

and why voltage of CH1 and CH2 is different in the graph?

Is it because distance of CH1 and CH2 is different to earlobe electrode?

Q2. I want to get EOG analog signal.

so, through the Userguide p.16 '4.4 Accessing ADS1299 Analog Signals'

I can get the analog signal through J5.

but, i don't know which pin is out pin.

My plan is that connect with ADS1299EEG FE analog out pin and DSP board.

Thank you:))

    Hey Minsu,

    I am required to repeat to you some disclaimers located on page 4 of the user's guide for the EVM.

    The ADS1299EEG-FE is to be used only under these conditions:

    • The ADS1299EEG-FE is intended of electrical evaluation of the features of the ADS1299 device in a laboratory, simulation, or development environment.
    • The ADS1299EEG-FE is not intended for direct interface with a patient, patient diagnostics, or with a defibrillator.
    • The ADS1299EEG-FE is intended for development purposes ONLY. It is not intended to be used as all or part of an end-equipment application.

    Unfortunately for liability reasons I cannot advise you on any setup in which you or anyone else is directly connected to the hardware.

    Regards,
