ECG, Wavelets and Cortex-M4

Hello
First of all a successful 2017 for all of us.

I'm looking for examples of C algorithms for applying the concept of wavelets to identify ECG patterns in data collected with a Cortex-M4, preprocessed and later sent to a Cortex-A for graphical re-ordering.

Well the focus is the wavelets for detection of standards for diagnosis and filtering of the signal, at the moment I am reading the book Bioeletrical Signal Processing in Cardiac and Neurological Application, but it does not bring very practical examples in C, it presents very well the mathematical formulas, But I'm still having trouble starting to convert such formulas to encoded algorithms.

Thanks
