Hello Folks,
Need Small favor in ECG-Lead-OFF Detection, below are the configuration and the test result. We are using ADS1296R as AFE.
We are able to find/status update Lead-OFF for LA and LL , But NOT RA,V1 and RL as with the CONFIG_Register -3 BIT1 and BIT0. Please kindly help us in this issue.
Lead Off Detection – Register Configuration:
Config 3: 0xFC
Lead OFF Reg: 0xE0
We also configured- 70-95% of the threshold current of 6-24nA range which are available in the Datasheet of ADS1296.
Lead_SENSP: 0x0E
Lead_SENSN: 0x0E
CONFIG 4: 0x22 (0x02 is the BIT1 for Lead off Comparator Enable)
Result : is the value in Status register. First 3(24bits) bytes is the Status register in every read(Continuous read mode) cycle.
