Wishbone controlled I2C controllers

I2Cwrapper is a firmware framework which helps you implement Arduino based I2C target (slave) devices for control of non-I2C hardware. Supports plain Arduinos, ESP8266, ESP32, SAMD, STM32, and ATtiny platforms.

Verilog module for I2C Master, up to 16 bit sub addr, 7bit slave address, and multiple byte read/write capable

Example code showing different communications such as TTL, SPI and I2C.

ESP32 fast bit-bang I2C library for Arduino, drop in replacement for Wire.h

I2C Bare metal drivers for stm32 f4 family of microcontrollers written in C from scratch .The driver contain apis for the user to send and receive data i2c communication . The driver has two flavor of apis polling based (blocking ) and Interrupt based (non blocking ) check examples in the Src folder for more reference .

Software I2C Implementation

USB device to I²C master adapter with Linux kernel support

This library is useful for FAST communicating with i2C or SMBus or PMBus devices using FTDI adapters. Typical message to message transmission delay is less than 1 millisecond.

A device agnostic I2C bus master, intended for use with a bus master controller address/databus cpu interface

A universal controller to manage different I²C sensors.

Benchmark for esp-idf i2c driver

Cross-platform software TWI (I2C) driver for master device

I2C communication between two Arduino Uno

This repository provides examples that demonstrates how to develop PSoC 4 MCU based digital designs. These examples help you to use peripherals like TCPWM, SCBs ( UART, SPI, I2C), Encoders/Decoders and general digital components.

Custom i2c modules and ip cores

A C++ implementation of TWI communication for ATMega

openMSP430 project ported to Terasic DE0 and DE0CV. (I2C master core and basic UART included)
