Communication
Embedded electronics is all about interlinking circuits (processors or other integrated circuits) to create a symbiotic system. In order for those individual circuits to swap their information, they must share a common communication protocol. Hundreds of communication protocols have been defined to achieve this data exchange, and, in general, each can be separated into one of two categories: parallel or serial. Serial UARTs, SPI, and I2C are used with many products in the SparkFun catalog to pass data. They can be used with a serial terminal to help troubleshoot issues or display data. However, there are other methods of communication some of which include IR, RS-232, RS-485, CAN, MIDI, and DMX. Check out the tutorials below to start relaying data between your devices!
