The C program ///// // // Program to demonstrate how an assembly language function can be called from C. If you're interested more in just getting something done specifically on the AVR, I recommend looking at that. One of the main XMEGA features the sensor uses is the I2C (Inter-Integrated Circut) or TWI (Two-Wire-Interface) serial data bus. Today it is available for almost any system and very widely used. As we know, there's no I²C on ATtiny85, not even the TWI (Two Wire Interface, which is basically I2C with a different name) that some other Atmel chips have, so I had to write my own that takes advantage on the built-in USI unit. C compatible two-wire interface. Starting from either a new project or an example project, Atmel START allows you to select and configure software components (from ASF4 and AVR Code), such as drivers and middleware to tailor your embedded application in a usable and optimized manner. Tuxgraphics AVR C-programming tutorial. There are several TWI examples in the SDK, and the most relevant is often the TWI Sensor Example, which uses the TWI master driver. 4) THE I2C INTERFACE Atmel calls their version of I2C the “two-wire” interface, or TWI. Our approach is to provide readers with the fundamental skills to quickly set up and operate with this internationally popular microcontroller.
