// Define the filter coefficients float filter_coeffs[3] = 0.1, 0.2, 0.3; This code defines a simple low-pass filter with

To implement this in C, you need a circular buffer . This prevents you from shifting the entire array of data every time a new sample comes in (which would kill your CPU cycles). : Reducing algorithm development time and managing memory
