Another active Raspberry Pi coder, Frank Buss, wrote some nice driver code but sadly didn't integrate it with Linux's own i2c driver framework. It worked, though not as I wanted it. He did the hard work. I then took his code (with his permission of course) and wrote a Linux i2c driver for it today The Raspberry Pi I2C Interface. Inter-Integrated Circuit (I2C) is a protocol for communicating with low-speed peripherals. You can connect multiple I2C devices, such ADCs, LCDs, and sensors, to the I2C pins on the Raspberry Pi hardware. Each I2C device on an I2C bus must have a unique address These two programs, one for Raspberry Pi, the other for Arduino respectively, demonstrate how both devices exchange information back in forth in single bytes over I2C. While the GPIO and I2C on Raspberry Pi are three volts, my Arduino Nano was operating at five volts

Those get wired directly to the same.. Besides controlling I2C modules, like display and sensors, I2C communication also can be implemented between 2 controllers. For example between Raspberry Pi and Arduino. The different compare to I2C module is, we need to create our own data protocol Last night I succeeded in getting my Raspberry Pi to do some basic I²C (also known as I2C, TWI, or SMBus) communication. I had to look around in a couple different places on the web to figure out how to do it, so I thought I would make this blog post to consolidate the knowledge
On all Raspberry Pi's except the earliest ones, the bus we're interested in is /dev/i2c-1. Very conveniently, the two signal pins as well as +3.3V and GND are all located near each other, on the RPi's pins 1/3/5/9. Here's a little board sitting on top with an LPC810 on i First things first, set up the Raspberry Pi to use I2C. Here's a good guide: Configuring Your Pi for I2C. (And another.) 1. Start by installing some extra packages (developer page here): sudo apt-get install python-smbus sudo apt-get install i2c-tools sudo apt-get install libi2c-dev As I just re-discovered after reinstalling Raspbian, by default only the superuser can access the I2C bus. (This may not be the case if you are using one of the official pre-installed SD card images).
