Part Number:ADS1298

Hi ,

I am using ADS1298 in my project to acquire 12 lead ECG and i am interfacing it to MSP430F5659.

1. I got my schematic right.

2. I have completed initialization of ADS1298 and Getting device ID  -  as 92h.

  The problem is when i am trying to read data from ADS1298 using SPI clock of 2Mhz i am getting data from ADS1298. I tried plotting each channel data taking MSB and LSB from received data combined MSB and LSB converted it to equivalent Decimal data and plotted using MS OFFICE EXCEL  but all i am getting is a random waveform nothing looking such as ECG.

Am i  doing any mistake in the process, If so please help me out with how to read correct data from ADS1298 and how to plot it .

Also if possible please send the  flow of how to read data from ADS1298 after configuration.

Thanks in advance.

i am also attaching channel 1 output waveform
