kalman-estimator - a Kalman estimator in C++

C++11/17/20 library for manipulating I/O port pins and I/O registers of AVR8

Turn on PC, server, computer automatically using arduino without the need of pressing the power switch (such as in ATX power supply). Once the power source is connected, arduino will immediately press the switch.

1V0 (Pronounced "Ivo".) Presented is a new programming language/virtual machine for low resource microcontrollers, retro homecomputers, Java MIDP 1.0/2.0 (CLDC 1.1) enabled phones, of assembler-like nature and operating on floating point (or fixed point) numbers as its exclusive data type, with implementations in C and Java for the command line.

A simple and effective open-source flight controller for quadcopters. Written in C++ and optimized for AVR processors like the ATmega2560, this project provides a lean and reliable core for any drone. It uses the BNO085 IMU for precise orientation and supports both standard PWM receivers and 4G modems for versatile, long-range control.

MyIDE replaces WINAVR. Users who want to move from Arduino-IDE to pure C++ are welcome.
