Moving Average Plus is a C++ library that implements a moving average on the Arduino platform. Performance and usability are the two focuses I thought of when creating this library, so every improvement tip is welcome. It is useful for filtering noisy data from sensors, for example.

Measure PWM signal frequency using the Raspberry Pi Pico's PIO (Programmable Input/Output) in MicroPython without cpu involvement.
