Hi everyone,
recently I have struggled to take ecg, eeg, eog signals from my body via ADS1299 EVM board. I have tried/searched lots of setting and setup until now but there is no my chance. actually I measured the internal/external test signals(between 10mvpp ~ 100mvpp amplitute ) . there is a point I could figure out; that is, why I can't measure any ecg,eog,eeg signals while measuring the external test signal anyway with same setup and register settings. I also designed a board which includes ads1299 and stm32f4 mcu, as a result it was happend again same thing I said. I really wonder where I did mistake at signal measuring ? for instance, I added below images which include external test signal, register settings and measuring ECG signal from my body respectively(as a note, I m using gold cup electrodes). I use bipolar supply, SRB2 pin and CH8N channel. generally I gather heterotaxic sinusoid signal from my body same as below one. also there is no difference towards ecg,eog or eeg and all of them seems as similar. if you help me at solving problem I would be appreciated. Thanks.
