Other Parts Discussed in Thread: ADS1298R

Hi Sir,

I am using ADS1298R ECG front end analog board. I have interfaced it with LPC2378 microcontroller using SPI communication. All the things works fine (Registers write and read), i have also read out the data of channel 2 and channel 3. But problem is with the chest leads V1 through V6 where i do not get any data afterall i have turned ON the WCT terminal. I dont know what to do. I can also share the register settings i have made if you ask. Please suggest some solution that how i can get the accurate data of leads V1 through V6.

    Hi Anup,

    Welcome to the E2E forum !! Thanks for the post.

    The WCT signal for the chest lead (V1-V6) is derived from the LA, RA, and LL electrodes through CH1 to CH4. Please see section 9.3.1.7.3 in the datasheet for the WCT implementation and usage.  The WCT signal will be connected to the negative input of the chest lead (V1-V6) channels externally. 

    Thanks
