The next step is to enable the Transmitter and Receiver to use UCSR0B register and load the UBR0 register with the data to transmit. The USART accepts all 30 combinations of the following as valid frame formats: The next step is to set the Frame Format using UCSR0C register. At 16Mhz the highest communication speed we can reach is 1Mbps. So from the above table, it is easy to choose the available baud rates with their respective UBBR0. The initialization process normally consists of setting the baud rate, setting frame format, and enabling the Transmitter or the Receiver. The three major hardware components that need to be initialized before any communication are Clock Generator, Transmitter, and Receiver.

One via USBasp to flash and another one for serial communication. In this condition, you need two USB connections to your Arduino. In case you are not using the Arduino’s serial programming to flash the microcontroller, you will also need an additional USBasp to connect your computer and Arduino board. You just have to connect the Arduino board with your computer via USB. If you are using Arduino UNO and Atmel Studio 7 / Arduino IDE.

The USART supports four modes of operation: Normal asynchronous, Double Speed asynchronous, Master synchronous, and Slave synchronous mode. The Receiver supports the same frame formats as the Transmitter and can detect Frame Error, Data OverRun, and Parity Errors.Įach of the hardware units needs to be configured by writing bits in their respective control registers. In addition to the recovery units, the Receiver includes a Parity Checker, Control logic, a Shift Register, and a two-level receive buffer (UDRn).

The recovery units are used for asynchronous data reception. The Receiver is the most complex part of the USART module due to its clock and data recovery units. The write buffer allows a continuous transfer of data without any delay between frames. The Transmitter consists of a single write buffer, a serial Shift Register, Parity Generator, and Control logic for handling different serial frame formats. The Clock Generation logic consists of synchronization logic for external clock input used by synchronous slave operation, and the baud rate generator. The major hardware components in USART are Clock Generator, Transmitter, and Receiver.

These support endless possible applications for this small and affordable package. A wide range of flexible I/O options includes I2C, SPI, and uniquely Programmable I/O (PIO).
