Chapter 17. I2C
I2C is a tremendously popular protocol for interfacing microcontrollers with small sensors and these days even with devices that require more speed. Its main advantage is that you can talk to a large number of devices with just a couple of wires, which makes it much more like a network than the SPI bus. When you find yourself wanting to talk with I2C devices, this chapter will get you a head start!
We’ll be continuing on from Chapter 16 toward building a logging I2C thermometer. If you use the SPI EEPROM chip from last chapter, the logger will be capable of recording the temperature at a variable frequency for at least a few days on AA batteries. Then, when you want to read the data back out, the AVR code ...
