KISS FFT converts a time-domain signal (a series of samples from a microphone, ADC, accelerometer, etc.) into the frequency domain, revealing which frequencies are present and how strong each one is.

Abstract: This brief presents a novel 4096-point radix-4 memory-based fast Fourier transform (FFT). The proposed architecture follows a conflict-free strategy that only requires a total memory of size ...

Mixed-precision computing [1]–[4] requires multiple levels of numerical precision and combines double-precision (FP64), single-precision (FP32), and even half-precision (FP16); it provides significant ...

Stepper motors use a cogged wheel and electromagnets to rotate the wheel one ‘step’ at a time. Each HIGH pulse sent to the A4988 stepper driver energises the coil, attracting the teeth closest to the ...

This library provides a simple device independent interface for interacting with Adafruit IO using Arduino. It allows you to switch between WiFi (ESP8266, ESP32, ESP32-S2, ESP32-S3, ESP32-C3, RP2040, ...
