| - | <code> | ||
| - | The Inter-integrated Circuit (I2C) Protocol is a protocol intended to allow multiple | ||
| - | “slave”digital integrated circuits (“chips”) to communicate with one or more “master” | ||
| - | chips. | ||
| - | |||
| - | Like the Serial Peripheral Interface (SPI), it is only intended for short distance | ||
| - | communications within a single device. Like Asynchronous Serial Interfaces (such as | ||
| - | RS-232 or UARTs), it only requires two signal wires to exchange information. | ||
| - | </code> | ||
| - | |||
| - | Many of the sensors used in the lab will use the I2C protocol. Therefore it is important that you understand what I2C at a fundamental level before you can use it. The sparkfun I2C page provides an excellent introduction so start with that first. Afterwards, the i2c-bus.org website will give a great primer as well as additional resource | ||
