ADS1294R: data get collapsed in continuous mode while read Config 3 reg

Part Number: ADS1294R
Other Parts Discussed in Thread: ADS1298R

Dear Friends

in continuous mode, I got 27-byte data from ads1294R in that data every first 3 byte notifies the lead off status(RA, LA, LL), but when I remove the RL I can't get the status of RL.

actually, I can read RL STATUS in the CONFIG3 register but at the time 27-bytes are not giving the current values it always throws old values. I want to Know the procedure of RL Lead removal status in continuous mode without affecting the 27-byte data

Thanks and regards

Hello Vivek,

Thank you for your post.

Are you using ADS1294R or ADS1298R? You should only be reading 15 bytes from the ADS1294R (STATUS + 4 Channels @ 3 bytes each). I'm also a bit confused by the title of the post since you cannot read data and register values at the same time.

Unfortunately, the comparator used to monitor the RLD electrode is always driven by the RLD amplifier. Therefore, RLD lead-off detection is only possible when the RLD amplifier is disabled. Please see this related post:
