ECG C5505 interface with Matlab/Simulink

Started by Talha Saleem May 31, 2011
hi,
I am doing ECG on C5505 EVM. i have successfully achieved the ECG. Now i want to interface the DSP with Matlab/Simulink(2010). I have connected the kit through serial port. right now i am using Simulink. i have tried Instrument Tool Box. There were two things,

1) When i use query instrument, the output to Scope is a straight line.
2)When i use Serial Recieve and a Demux, there is a output but its all noise. and furthermore i cant figure out how to differentiate all the leads' data coming in.

I am stuck here. So can anyone advice me on this.

Regards,
Talha.
