Actually, a ECG platform, a research project from college.
There's that "ECG platform" again. What is it? What is it going to do? Who is going to use it and how would they use it?
I want to do a real-time signal collector, filter and monitor for ECG signals.
But, I really want to know how.
You really need to get a handle on what exactly it is that you are supposed to be doing and why.
What do you already know about:
- real-time signal collection
- digital signal filtering
- C/C++ programming for an Arduino
You seem to be starting from zero knowledge about what is involved and, as I've mentioned before, this is not a teaching forum.
Do your college courses cover any of the subjects I've mentioned above? Your college is where you should be learning this stuff. If they don't teach it, then I don't see why you have a "research project" which involves subjects they don't cover.
I think you've bitten off far more than you can chew. You need to start with something much smaller and simpler and build your way up.
