USCI - UART
Serial communication is perhaps the most widely used communication method for interfacing a PC or
other machines with a micro and over long distances. With just two cross-connecting wires, we can
achieve a full-duplex point-to-point communication. Owing to its simplicity, range and wide usage, it
is the communication interface backbone that is used for GSM modems, RF modules, Zigbee devices
like CC2530, BLE devices like CC2540, Wi-Fi devices like CC3200, etc. Other forms of advance serial
communications have their lineages tracing back to it, for example, RS-485, LIN, IrDA, etc.
Shown below is a demo of HMC1022-based LED compass. To communicate with this chip to get
compass heading, we need to send-receive data via UART.
