At present, we have found a problem when debugging ADS1299. The DRDY pin waveform sometimes appears as follows, resulting in the failure of reading data:
1.DRDY lag time is too long, about 2ms;
2. DRDY has the backward situation, the normal is a lower after about 10 us up, this time with new data, abnormal, DRDY has kept a low level (2 ms) up (about 10 us), pull down again.Please see the screenshot below
DRDY is too long.
DRDY wave is reversed.
So, I want to know, what are the conditions for DRDY to be affected?
Thanks.
