sorry for my late response. I was really busy these days.

thanks for the info. I will do some changes and tests.

I do not know if it is suitable for this project, but I had good results with Darrels Taylor ADC oversampling routines (http://dt.picbasic.co.uk/CODEX/AnalogueOverSampling).

Also Kalman filters maybe of use. I find them difficult to implement though.

no amount of low pass filtering will remove the dc component, ultimately it just makes it worse.
the dc component needs to be removed to make detection of the beat peaks reliable.
there is plenty of raw data posted, you can always ask for more. feel free to have a go

I am not currently on this project. Was disappointed and set it aside. Removing DC component with firmware I think is too difficult.

The oversampling of DT routines were tested and applied on other projects with amazing results (costing in program speed of course, nothing is free).
