libwxfreq is a generic high performance frequency limitation library

[FPGA 2021, Best Paper Award] An automated floorplanning and pipelining tool for Vivado HLS.

A simple MEMS I2S microphone and audio processing library for ESP32.

Estimate ocean wave height (or vessel heave), waves direction, and period from accelerations using IMU on esp32 using advanced Kalman filters

APDOB - Adaptive Periodic-Disturbance Observer

Smart library with comprehensive functions for counting (multiple) frequencies and period-times. For Arduino Uno and Zero.

C++ component for esp-idf which allow playing sound via DAC with mixing

my own audio visualizer (library), because after effects sucks

An example code for modulating the resonant frequencies of LRAs on DRV2605.

Inductance and Resistance meter, Arduino based. Push button input. 3 tests, 4 resistor test ranges. One Inductance test, Analog input display , outputs to serial monitor and OLED. Resistor range is from 0 ohms to 2 Mohms , Inductor range is 80uH to 30,000uH.

AVR PWM generator with user interface

Advanced Arduino Frequency Scanner This project upgrades the basic pulse‐counting scanner into a high‐resolution, wide‐range instrument using Arduino’s Timer1 Input Capture. You’ll get instant period readings, automatic smoothing, dynamic range up to several MHz, and a clean I²C LCD interface.

Arduino project to measure mains/grid frequency and publish it as SSE and MQTT streams

Calibrate the output frequency of the Adafruit PCA9685 I2C 16 channel servo driver

Clock generator with quadrature phase signal and OLED display.

This project implements a versatile waveform generator using an ESP32 microcontroller. It generates various types of waveforms with adjustable parameters such as frequency, amplitude, and phase. Additionally, it features sweep and burst modes for more complex signal generation.

A fork of the well-known "PWM frequency library" initially created by Sam Knight

This is an example app for the CustomMatPlot Library.

Very minimalistic 20meter transceiver Digital Frequency Synthesizer with 0.96 or 1.3 inch 128x64 OLED Display for Ham-radio use
