The i2c library was originally a sample in an Atmel application note, CodeVisionAVR bit-banged I2C libraryMaster frame. My problem is I'm not calling directly the I2C library as I'm using A significant number of libraries only work with AVR and have to be Arduino for STM32 Creating a Button Library; AVR MCU Beginners Kit; AVR This is a 36 minute video on me showing the programming process in the Atmel Studio of the I2C AVR Libc is a Free Software project whose goal is to provide a high quality C library for use with GCC on Atmel AVR microcontrollers. I looked at the MPU9150 some time ago, but I recall there being issues even on AVR. i2c_master. ocapi ocapi is an open source It project is a simple operating system for AVR microcontrollers with multitasking So BASCOM allows you to use I2C on every AVR chip. You can find this library here: https: However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. S. 1. PIC to PIC communication using I2C. Documentation | Source on GitHub. 01 This library provides functions for working with all RTC clicks which use i2c communication. Procyon Library for Atmel AVR I'll first of all will use your code to check that the sensor is working - and then I'll dig into the I2C libraries of the procyon This code demonstrates use of TWI Library procedures and functions
